[0044] The present application provides a FRP (Fiber Reinforced Plastics, fiber reinforced composite material) sculpture processing technology, including the following steps: obtaining a first mold base and a second mold base; performing FRP production on the first mold base and the second mold base respectively to form a first FRP shell and a second FRP shell; obtaining a skeleton and placing the skeleton at a preset position of the first FRP shell; performing FRP production on the skeleton to form a first FRP fixing layer to fix the skeleton on the first FRP shell. Performing a mold closing operation on the first mold base and the second mold base so that the skeleton is coated in the first FRP shell and the second FRP shell to obtain a semi-finished FRP composite sculpture body; performing a demolding operation on the semi-finished FRP composite sculpture body to obtain the FRP composite sculpture body.

[0045] The above-mentioned FRP composite sculpture body processing technology can form a first FRP shell and a second FRP shell respectively inside the first mold base and the second mold base by making FRP inside the first mold base and the second mold base respectively, thereby providing a support structure for the appearance of the FRP composite sculpture body, that is, providing a better support effect for the subsequent skeleton, and then placing the skeleton at a preset position of the first FRP shell, and making FRP on the skeleton, so that the first FRP fixing layer can fit on the surface of the skeleton and can be bonded to the first FRP shell, so that the connection strength between the skeleton and the first FRP shell can be enhanced, and then the first mold base and the second mold base are closed, so that the skeleton can be covered in the first FRP shell and the second FRP shell, effectively avoiding the phenomenon that the skeleton is easily caused to fall off by external force, and finally the demolding operation is performed to obtain the FRP composite sculpture body, thereby completing the processing of the FRP composite sculpture body. By adopting the above processing technology, during the production of FRP, the liquid FRP resin is convenient for the user to brush the formed first mold base, the second mold base and the skeleton to obtain the first FRP shell, the second FRP shell and the first FRP fixing layer. Since the FRP resin of the first FRP fixing layer can flow into the first FRP shell, when the liquid FRP resin is cooled and solidified, the first FRP shell and the first FRP fixing layer can be adhered together, so that the skeleton can be fixed on the first FRP shell, thereby avoiding the phenomenon that the skeleton of the FRP composite sculpture is easy to fall off when in use, and ensuring that the FRP composite sculpture with good structural strength is obtained.

[0046] In order to better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below in conjunction with specific embodiments:

[0047] like Figure 1 As shown, the FRP composite sculpture body processing process in one embodiment includes some or all of the following steps:

[0048] S110, obtaining a first mold base and a second mold base, so as to provide bearing support for FRP resin during subsequent FRP production, so that the FRP resin can be better attached to the first mold base and the second mold base.

[0049] S120, the first mold base and the second mold base are respectively made of FRP to form a first FRP shell and a second FRP shell, so that the FRP resin can adhere to the first mold base and the second mold base, and can form the first FRP shell and the second FRP shell with good structural strength, thereby providing a supporting structure for the shape of the FRP composite sculpture body, that is, providing a better supporting effect for the subsequent skeleton.

[0050] S130, obtaining a skeleton, and placing the skeleton at a preset position of the first FRP shell, so that during the subsequent mold closing operation, the skeleton can be located at a relatively balanced position between the first FRP shell and the second FRP shell, so that during subsequent installation, the FRP composite sculpture can be stably and reliably erected on the large cultural square.

[0051] S140, fabricating the frame with FRP to form a first FRP fixing layer so that the frame is fixed on the first FRP shell.

[0052] It can be understood that by making FRP on the skeleton, the FRP resin can be attached to the skeleton and the first FRP shell, and a first FRP fixing layer is formed on the surface of the skeleton and the first FRP shell. In this way, the first FRP fixing layer can fix the skeleton to the first FRP shell, and the connection strength between the skeleton and the first FRP shell can be strengthened, thereby avoiding the phenomenon that the skeleton of the FRP composite sculpture is easy to fall off when in use, and ensuring that a FRP composite sculpture with good structural strength is obtained.

[0053] S150, performing a mold closing operation on the first mold base and the second mold base so that the skeleton is covered in the first FRP shell and the second FRP shell to obtain a semi-finished FRP composite sculpture body.

[0054] It can be understood that when the first mold base and the second mold base are closed, the FRP resins in the first FRP shell and the second FRP shell can adhere to each other, and the skeleton can be wrapped in the first FRP shell and the second FRP shell, thereby effectively avoiding the phenomenon that the skeleton is easily caused to fall off by external force, so as to ensure that a FRP composite sculpture with good structural strength is obtained.

[0055] S160, performing a demolding operation on the semi-finished FRP composite sculpture body, and removing the first mold base and the second mold base to expose the FRP composite sculpture body, so as to obtain the FRP composite sculpture body.

[0056] The above-mentioned FRP composite sculpture body processing technology can form a first FRP shell and a second FRP shell respectively inside the first mold base and the second mold base by making FRP inside the first mold base and the second mold base respectively, thereby providing a support structure for the appearance of the FRP composite sculpture body, that is, providing a better support effect for the subsequent skeleton, and then placing the skeleton at a preset position of the first FRP shell, and making FRP on the skeleton, so that the first FRP fixing layer can fit on the surface of the skeleton and can be bonded to the first FRP shell, so that the connection strength between the skeleton and the first FRP shell can be enhanced, and then the first mold base and the second mold base are closed, so that the skeleton can be covered in the first FRP shell and the second FRP shell, effectively avoiding the phenomenon that the skeleton is easily caused to fall off by external force, and finally the demolding operation is performed to obtain the FRP composite sculpture body, thereby completing the processing of the FRP composite sculpture body. By adopting the above processing technology, during the production of FRP, the liquid FRP resin is convenient for the user to brush the formed first mold base, the second mold base and the skeleton to obtain the first FRP shell, the second FRP shell and the first FRP fixing layer. Since the FRP resin of the first FRP fixing layer can flow into the first FRP shell, when the liquid FRP resin is cooled and solidified, the first FRP shell and the first FRP fixing layer can be adhered together, so that the skeleton can be fixed on the first FRP shell, thereby avoiding the phenomenon that the skeleton of the FRP composite sculpture is easy to fall off when in use, and ensuring that the FRP composite sculpture with good structural strength is obtained.

[0057] In one embodiment, the production of the FRP includes the following specific steps: applying FRP resin to form an FRP resin layer; and applying fiber cloth to the FRP resin layer to form an FRP layer.

[0058] It can be understood that, due to the good designability and strength of FRP resin, various products with good structural strength can be flexibly designed according to actual production needs, that is, FRP resin becomes liquid FRP resin under heating conditions, and has good fluidity, which is convenient for users to brush the liquid FRP resin on the formed structure. For example, by brushing on the first mold base, the second mold base and the skeleton, an FRP layer with a certain structure, namely, the first FRP shell, the second FRP shell and the first FRP fixed layer, can be obtained. In this embodiment, the FRP resin is first brushed, and then the cloth is pasted, so that the liquid FRP resin can penetrate into the fiber cloth. When the FRP resin is cooled and solidified, it can be hardened on the formed structure to form the first FRP shell, the second FRP shell and the first FRP fixed layer.

[0059] Furthermore, since both the FRP resin and the fiber cloth have certain strength and the fiber cloth is light in weight, a first FRP shell, a second FRP shell and a first FRP fixing layer that are light and have good structural strength can be obtained, thereby providing a better supporting structure and fixing structure for the skeleton, so that the skeleton can be well fixed in the first FRP shell and the second FRP shell, and a light FRP composite sculpture body with good structural strength can be obtained for easy transportation.

[0060] In one embodiment, the step of using fiber cloth to apply cloth to the first FRP shell includes the following specific steps: obtaining the cut fiber cloth, attaching the fiber cloth to the first FRP shell, and the fiber cloth at least partially protrudes from the first mold base. Similarly, the step of using fiber cloth to apply cloth to the second FRP shell includes the following specific steps: obtaining the cut fiber cloth, attaching the fiber cloth to the second FRP shell, and the fiber cloth at least partially protrudes from the second mold base. In this way, the protruding fiber cloth facilitates better mold closing operation between the first FRP shell and the second FRP shell, and can form mold closing edges on the first FRP shell and the second FRP shell, so that the mold closing edges can be fixed later, thereby obtaining an FRP composite sculpture with good structural strength.

[0061] In one embodiment, the brushing operation controls the thickness of the resin to be 3 mm to 8 mm to ensure that the fiber cloth attached to the first FRP shell, the second FRP shell and the first FRP fixing layer can fully and comprehensively absorb the FRP resin, thereby obtaining the first FRP shell, the second FRP shell and the first FRP fixing layer with better structural strength.

[0062] In one embodiment, the fiber cloth includes at least one of glass fiber felt and glass fiber cloth. Since the glass fiber felt has a dense structure and small pores, the addition of glass fiber felt can increase the structural thickness and strength of the FRP layer. Since the glass fiber cloth is mainly glass fiber mesh cloth, it not only has good toughness, but also is not easy to deform and has good compressive resistance. The added glass fiber cloth is beneficial to the shaping of the FRP resin, so that the first FRP shell, the second FRP shell and the first FRP fixed layer with better molding effect and stronger structure can be obtained on the first mold base, the second mold base and the skeleton.

[0063] In one of the embodiments, the step of performing FRP on the skeleton to form a first FRP fixing layer so that the skeleton is fixed on the first FRP shell includes the following specific steps: repeating the FRP production on the skeleton at least once to form multiple layers of the first FRP fixing layer on the skeleton, which can further strengthen the connection strength between the skeleton and the first FRP shell.

[0064] In one of the embodiments, the step of performing FRP production on the first mold base and the second mold base to form a first FRP shell and a second FRP shell includes the following specific steps: repeating the FRP production at least once inside the first mold base to form a multi-layered first FRP shell to improve the connection strength of the first FRP shell.

[0065] In one embodiment, the FRP manufacturing is repeated at least once inside the second mold base to form the second FRP shell having at least multiple layers, so as to improve the connection strength of the second FRP shell.

[0066] like Figure 4 As shown, in one embodiment, the first FRP shell 110 includes a first FRP base layer 111 and a plurality of first FRP sub-layers 112 stacked with each other, the first FRP base layer 111 is attached to the first mold base, and each first FRP sub-layer 112 is sequentially attached to the first FRP base layer 111, the first FRP base layer 111 is applied with glass fiber felt, and each first FRP sub-layer 112 is applied with glass fiber cloth, so that the glass fiber felt of the first FRP base layer 111 can absorb the FRP resin well, on the one hand, the thickness of the first FRP shell 110 is improved, and on the other hand, when the glass fiber felt is attached to the FRP resin, since the pores of the glass fiber felt are small and there are more fluffs on the surface, most of the FRP resin can adhere to the fluffs on the surface of the glass fiber felt, so as to form a FRP film layer with good structural strength in the radial plane of the glass fiber felt, and a smaller portion of the FRP resin can penetrate into the interior of the glass fiber felt to achieve bonding with the FRP in the first FRP sub-layer 112. The connectivity of the resin, i.e. the glass fiber mat, can effectively reduce the flow of the resin in the first FRP sublayer 112 to the first FRP base layer 111, thereby effectively avoiding the phenomenon that the resin in the first FRP sublayer 112 diffuses in large quantities to the first FRP base layer 111, causing the first FRP sublayer 112 to have a slow shaping speed and poor shaping effect, thereby obtaining an FRP composite sculpture body 10 with a better structural shape and higher strength.

[0067] Similarly, in one embodiment, each second FRP shell 120 includes a stacked second FRP base layer 121 and a plurality of second FRP sub-layers 122, the second FRP base layer 121 is attached to the second mold base, and each second FRP sub-layer 122 is sequentially attached to the second FRP base layer 121, the second FRP base layer 121 is applied with glass fiber felt, and each second FRP sub-layer 122 is applied with glass fiber cloth, so that the glass fiber felt of the second FRP base layer 121 can absorb the FRP resin well, on the one hand, the thickness of the second FRP shell 120 is improved, and on the other hand, when the glass fiber felt is attached to the FRP resin, since the pores of the glass fiber felt are small and there are more fluffs on the surface, most of the FRP resin can adhere to the fluff on the surface of the glass fiber felt, so as to form a FRP film layer with good structural strength on the radial plane of the glass fiber felt, and a smaller portion of the FRP resin can penetrate into the interior of the glass fiber felt to achieve bonding with the FRP in the second FRP sub-layer 122. The connectivity of the resin, i.e., the glass fiber mat, can effectively reduce the flow of the resin in the second FRP sublayer 122 to the second FRP base layer 121, thereby effectively avoiding the phenomenon that the resin in the second FRP sublayer 122 diffuses in large quantities to the second FRP base layer 121, causing the second FRP sublayer 122 to have a slow shaping speed and poor shaping effect, thereby obtaining an FRP composite sculpture body 10 with a better structural shape and higher strength.

[0068] In one embodiment, the glass fiber mat is an alkali-free glass chopped strand mat, and the glass fiber cloth is an alkali-free glass fiber cloth. Since the alkali-free glass chopped strand mat has a faster penetration speed, the FRP resin can form an FRP film layer on the alkali-free glass chopped strand mat faster and better, that is, the first FRP base layer 111 and the second FRP base layer 121 can be quickly formed. Since the alkali-free glass fiber cloth has good tensile strength and is easy to combine with the FRP resin to form a FRP layer with good strength, a plurality of first FRP sub-layers 112 and a plurality of second FRP sub-layers 122 with good shaping effect and high structural strength can be obtained, so that the FRP composite sculpture body 10 has a three-dimensional spatial structure with good structural shape and high structural strength.

[0069] In this embodiment, the alkali-free glass chopped strands mat is EMCL300-1040 alkali-free glass chopped strands mat, and the alkali-free glass fiber cloth is EWR400-100 alkali-free glass fiber cloth. Since the alkali-free glass chopped strands mat of EMCL300-1040 and the alkali-free glass fiber cloth of EWR400-100 have higher strength and the content of alkali metal oxide is less than 0.8%, when the alkali-free glass chopped strands mat of EMCL300-1040 and the alkali-free glass fiber cloth of EWR400-100 are used in combination with the FRP resin layer, not only the structural strength of the FRP composite sculpture body 10 can be improved, but also a highly environmentally friendly FRP composite sculpture body 10 can be obtained, that is, it can play a better protective role on the ecological environment, reduce pollution to the environment, and also play a better protective role on the operator.

[0070] like Figure 3 As shown, in one embodiment, the skeleton 210 includes a main rod 211 and a secondary rod 212 welded together, so that a connected skeleton 210 can be obtained, so that the user can place the skeleton 210 at a preset position of the FRP fixed layer at one time, thereby improving the production efficiency of the FRP composite sculpture body 10.

[0071] In one embodiment, the skeleton 210 is a hollow metal structure, so that the connection structure of the FRP composite sculpture body 10 can be ensured while also ensuring that a lighter FRP composite sculpture body 10 can be produced.

[0072] In one embodiment, the skeleton 210 is hollow stainless steel, so that the hollow stainless steel can have good structural strength and be easy to transport by users, and can also prevent the skeleton 210 from rusting, thereby increasing the service life of the FRP composite sculpture body 10.

[0073] like Figure 3 As shown, in one embodiment, the skeleton 210 also includes reinforcing ribs 213, and the reinforcing ribs 213 are used to strengthen the connection strength between the main rod 211 and the secondary rod 212. By adding a plurality of reinforcing ribs 213, the connection area between the skeleton 210 and the first FRP shell 110 can be increased. When the FRP composite sculpture body 10 is erected and fixed on a large cultural square, the gravity of the FRP composite sculpture body 10 can be well dispersed from the main rod 211 and the secondary rod 212 to the reinforcing ribs 213, so that the FRP composite sculpture body 10 can be erected and fixed on the large cultural square more stably and reliably, avoiding the phenomenon that the FRP composite sculpture body 10 is easily lost balance under the action of external force.

[0074] In one embodiment, there are multiple reinforcing ribs 213, the axial plane of the main rod 211 is perpendicular to the axial plane of the FRP composite sculpture body 10, the radial plane of the secondary rod 212 is perpendicular to the axial plane of the FRP composite sculpture body 10, there are multiple main rods 211, there are multiple secondary rods 212, each of the secondary rods 212 is arranged on each of the main rods 211 at intervals, and a plurality of grids are formed at intervals, each of the reinforcing ribs 213 is arranged in a grid, so that each adjacent two reinforcing ribs 213 and a secondary rod 212 can form a plurality of triangles, so that when the FRP composite sculpture body 10 is erected and fixed on a large cultural square, the plurality of triangles can provide a relatively stable support for the FRP composite sculpture body 10, thereby improving the overall structural strength of the FRP composite sculpture body 10.

[0075] In order to prevent the corners of each triangle from being too sharp and easily damaging the first FRP shell 110, the second FRP shell 120 and the fiber cloth of the first FRP fixing layer, the connecting part of the corners of each triangle is specifically an arc angle, so that the sharp corners can effectively prevent the user from damaging the fiber cloth when placing the frame 210.

[0076] In one of the embodiments, FRP is made on each of the main rods 211, each of the secondary rods 212 and each of the reinforcing ribs 213, so that a plurality of first FRP fixing layers are formed on the main rods 211, each of the secondary rods 212 and each of the reinforcing ribs 213. In this way, each of the main rods 211, each of the secondary rods 212 and each of the reinforcing ribs 213 can be fixed, thereby further improving the connection strength of the FRP composite sculpture body 10.

[0077] In order to prevent the skeleton 210 from shaking and shifting, in one embodiment, the FRP composite sculpture body 10 also includes a limiter 214, the size of which is adapted to the first mold base so that the limiter 214 can achieve fixed positioning of the skeleton 210, thereby preventing the skeleton 210 from shaking and shifting under the application of external force.

[0078] In this embodiment, there are multiple limit members 214, so that multiple limit members 214 can simultaneously limit and fix the skeleton 210, thereby further increasing the limit fixation of the skeleton 210, thereby avoiding the phenomenon that the skeleton 210 is easily shaken and displaced under the use of external force.

[0079] In the present embodiment, each of the limiting members 214 is I-shaped, and the limiting members 214 include a first connecting member, a second connecting member, and a third connecting member connected to each other, the first connecting member and the third connecting member are respectively abutted against the first FRP shell 110, the first connecting member and the third connecting member are both provided with a second FRP fixing layer, and each of the second FRP fixing layers is connected to the first FRP shell 110. In this way, a plurality of I-shaped limiting members 214 can simultaneously limit and fix the skeleton 210, thereby greatly improving the connection strength between the skeleton 210 and the first FRP shell 110, thereby avoiding the phenomenon that the skeleton 210 is easy to fall off. Furthermore, since the first FRP fixing layer is also formed on the frame 210, the first FRP fixing layer and the multiple I-shaped limiting members 214 can simultaneously limit and fix the frame 210, achieving a double fixing effect, which can further improve the connection structure between the frame 210 and the first FRP shell 110, more effectively avoid the phenomenon that the frame 210 is easy to fall off, and obtain a FRP composite sculpture body 10 with good structural strength. In addition, since the first connecting member and the third connecting member have a large contact area with the first FRP shell 110 and have no sharp edges and corners, the phenomenon of damaging the fiber cloth in the first FRP shell 110 can be effectively avoided, thereby ensuring the self-strength of the fiber cloth in the first FRP shell 110, that is, ensuring the structural strength of the first FRP shell 110.

[0080] In one embodiment, the limiting members 214 are evenly distributed on the frame 210 to obtain a FRP composite sculpture body 10 with even force, thereby ensuring the balance of the FRP composite sculpture body 10.

[0081] In one of the embodiments, the skeleton 210 is placed at a preset position of the first FRP shell 110, and then the various limiting members 214 are evenly placed on the skeleton 210, and then the skeleton 210 and the various limiting members 214 are respectively made of FRP, so that a plurality of first FRP fixing layers can be formed on the skeleton 210, and a second FRP fixing layer can be formed on each limiting member 214. In this way, the skeleton 210 and the various limiting members 214 can be fixed at one time. Not only is the operation method simple and fast, but the production efficiency of the FRP composite sculpture body 10 is improved.

[0082] like Figure 5As shown, in one embodiment, the skeleton 210 also includes a plurality of first hollow metal sleeves 2151 and a plurality of second hollow metal sleeves 2161, each of the first hollow metal sleeves 2151 is protruded on the first side of the skeleton 210, and each of the first hollow metal sleeves 2151 is used to fix the skeleton 210 to the first FRP shell 110, each of the second hollow metal sleeves 2161 is protruded on the second side of the skeleton 210, and each of the second hollow metal sleeves 2161 is used to fix the first FRP fixing layer, and the first side is arranged opposite to the second side.

[0083] It can be understood that since each first hollow metal sleeve 2151 and each second hollow metal sleeve 2161 are protruded and arranged on the first side and the second side of the skeleton 210, the size of each first hollow metal sleeve 2151 and each second hollow metal sleeve 2161 is adapted to the pores of the fiber cloth, so that the user can use multiple first hollow metal sleeves 2151 to quickly and accurately engage the skeleton 210 in the preset position of the first FRP shell 110 without displacement, and the multiple second hollow metal sleeves 2161 can provide better positioning for the fiber cloth in the first FRP fixing layer, so that the fiber cloth of the first FRP fixing layer can be well engaged with the multiple second hollow metal sleeves 2161, thereby fixing the skeleton 210 well on the first FRP shell 110 and the first FRP fixing layer, further improving the connection strength between the skeleton 210 and the first FRP shell 110 and the first FRP fixing layer. Furthermore, since the first hollow metal sleeve 2151 and the second hollow metal sleeve 2161 are hollow in shape, when each first hollow metal sleeve 2151 and each second hollow metal sleeve 2161 are engaged on the first FRP shell 110 and the first FRP fixing layer, the FRP resin can flow into and fill the interior of each first hollow metal sleeve 2151 and each first hollow metal sleeve 2151. When the FRP resin is cooled and solidified, a plurality of first FRP inserts 2152 can be formed on the plurality of first hollow metal sleeves 2151 and the first FRP shell 110, and a plurality of second FRP inserts 2162 can be formed on the plurality of second hollow metal sleeves 2161 and the first FRP fixing layer, thereby further improving the connection strength between the skeleton 210 and the first FRP shell 110 and the first FRP fixing layer, thereby improving the connection strength of the FRP composite sculpture body 10.

[0084] like Figure 5As shown, in one embodiment, the first positioning member 215 includes the first hollow metal sleeve 2151 and the first FRP insert 2152 to achieve the connection strength between the skeleton 210 and the first FRP shell 110. Similarly, the second positioning member 216 includes the second hollow metal sleeve 2161 and the second FRP insert 2162 to achieve the connection strength between the skeleton 210 and the second FRP shell 120.

[0085] like Figure 5 As shown, in one embodiment, the first hollow metal sleeve 2151 and the second hollow metal sleeve 2161 are both funnel-shaped. Since the funnel shape has a wide end and a pointed end, the wide end is welded to the skeleton 210. In this way, it is convenient for the user to smoothly insert the first hollow metal sleeve 2151 and the second hollow metal sleeve 2161 into the first FRP shell 110 and the first FRP fixed layer respectively. Moreover, since the wide ends of the first hollow metal sleeve 2151 and the second hollow metal are welded to the skeleton 210, the connection strength between the first hollow metal sleeve 2151 and the second hollow metal sleeve 2161 and the skeleton 210 can be increased, so that the first FRP sublayer 112 connected to the skeleton 210 and the first FRP fixed layer are not easy to fall off, thereby improving the connection strength between the skeleton 210 and the first FRP shell 110 and the first FRP fixed layer.

[0086] like Figure 4As shown, in one embodiment, the first positioning member 215 further includes at least a first bending deformation portion 2153, each of which is disposed at one end of the first positioning member 215 away from the frame 210, which not only facilitates the user to insert the first positioning member 215 into the first FRP shell 110, but also when the external force disappears, each of the first bending deformation portions 2153 will deform, thereby realizing the limiting fixation of the first FRP shell 110, thereby preventing the frame 210 and the first FRP shell 110 from easily falling off. Similarly, in other embodiments, the second positioning member 216 further includes at least one second bending deformation portion 2163, each of which is disposed at one end of the second positioning member 216 away from the frame 210, thereby realizing the limiting fixation of the first FRP fixing layer 220, thereby preventing the frame 210 and the first FRP fixing layer 220 from easily falling off. In order to better improve the connection strength between the skeleton 210 and the first FRP shell 110 and the first FRP fixing layer 220, in some embodiments, the first positioning member 215 also includes at least one first bending deformation portion 2153 and the second positioning member 216 also includes at least one second bending deformation portion 2163. In this way, the connection strength between the skeleton 210 and the first FRP shell 110 and the first FRP fixing layer 220 can be further improved, and the structural strength of the FRP composite sculpture body 10 can be further improved.

[0087] like Figure 4 As shown, in one embodiment, the bending angles of the first bending deformation part 2153 and the second bending deformation part 2163 are both acute angles, so that the first bending deformation part 2153 and the second bending deformation part 2163 can be deformed better, so that the user can more smoothly insert the skeleton 210 into the first FRP shell 110 and the first FRP fixing layer during production and assembly. In one embodiment, the angle is 15° to 55 degrees, so that the user can more quickly and smoothly insert the positioning piece into the multi-layer first FRP shell 110 or the multi-layer first FRP fixing layer.

[0088] like Figure 6As shown, in order to prevent the first FRP shell 110 engaged with the first positioning member 215 from being easily displaced, and the first FRP fixing layer engaged with the second positioning member 216 from being easily displaced, in one embodiment, the first bending deformation portion 2153 is provided with a first sawtooth 2154 on a side facing the first hollow metal sleeve 2151, and the second bending deformation portion 2163 is provided with a second sawtooth on a side facing the second hollow metal sleeve 2161. In this way, on the one hand, it is beneficial for the first bending deformation portion 2153 to be easily displaced. The second bending deformation part 2163 is better deformed under the action of external force, so that the user can more smoothly insert the skeleton 210 into the first FRP shell 110 and the first FRP fixed layer. On the other hand, since the first bending deformation part 2153 is provided with a first serration 2154 on the side facing the first hollow metal sleeve 2151, when the external force disappears, the first serration 2154 can clamp the fiber cloth engaged in the first FRP shell 110 on the first hollow metal sleeve 2151, and the second serration can clamp the fiber cloth engaged in the first FRP fixed layer on the second hollow metal sleeve 2161, thereby further improving the connection strength between the first positioning member 215 and the first FRP shell 110, thereby improving the connection strength between the second positioning member 216 and the first FRP fixed layer, and further improving the connection strength between the skeleton 210, the first FRP shell 110 and the first FRP fixed layer.

[0089] In one of the embodiments, the length of the first hollow metal sleeve 2151 is less than the sum of the thicknesses of the multiple layers of the first FRP shell 110, so as to ensure that the first hollow metal sleeve 2151 is engaged with the first FRP sublayer 112. In this way, while ensuring that the first positioning member 215 and the first FRP shell 110 have a strong connection strength, it is also possible to ensure that the FRP composite sculpture body 10 has good flatness, thereby improving the product quality of the FRP composite sculpture body 10.

[0090] Similarly, in one embodiment, the length of the second positioning member 216 is less than the sum of the thicknesses of the multiple layers of the first FRP fixing layer, so as to ensure that the first hollow metal sleeve 2151 is engaged on the first FRP sub-layer 112. In this way, while ensuring that the second positioning member 216 and the first FRP fixing layer have a strong connection strength, it is also possible to ensure that the FRP composite sculpture body 10 has good flatness, thereby improving the product quality of the FRP composite sculpture body 10.

[0091] In one embodiment, the step of obtaining the first mold base and the second mold base includes the following specific steps: using a plastic material to cast a mold on the formed model; and segmenting the mold to obtain the first mold base and the second mold base.

[0092] It can be understood that a model is first made by foam or 3D printing, and then a mold is made on the molded model using a plastic material to obtain a mold with a certain structural shape, and then the mold is cut and the model in the mold is removed to obtain a first mold base and a second mold base with a cavity, so that the FRP fixing layer can be made in the cavity of the first mold base and the second mold base later, thereby providing basic support for the FRP fixing layer. In one embodiment, the plastic material is plaster or mud, so that the user can make a mold.

[0093] In one embodiment, after the step of demolding the semi-finished FRP composite sculpture body to obtain the FRP composite sculpture body, the FRP composite sculpture body processing technology further includes the following step: fixing the mold edge of the FRP composite sculpture body. Specifically, the multi-layer fiber cloth protruding from the first mold base and the multi-layer fiber cloth protruding from the second mold base are overlapped and stacked together layer by layer to form a stacked structure, and then the FRP resin is used for brushing operation, so that the mold edge can be attached to the first FRP shell and the first FRP fixed layer more evenly, thereby improving the connection strength of the FRP composite sculpture body.

[0094] In one of the embodiments, after the step of fixing the mold edge of the FRP composite sculpture body, the FRP composite sculpture body processing technology also includes the following steps: grinding the mold edge of the FRP composite sculpture body, so that the excess scraps on the mold edge can be effectively removed to obtain the FRP composite sculpture body with a smoother surface.

[0095] In one of the embodiments, the step of grinding the mold edges of the FRP composite sculpture body includes the following specific steps: grinding the mold edges of the FRP composite sculpture body using a grinder to quickly remove excess scraps.

[0096] In one of the embodiments, after the step of grinding the mold edges of the FRP composite sculpture body, the FRP composite sculpture body processing technology also includes the following steps: repairing the surface of the FRP composite sculpture body with putty to obtain a FRP composite sculpture body with higher flatness; coloring the FRP composite sculpture body to obtain a colorful FRP composite sculpture body.

[0097] like Figures 1 to 3As shown, the present application also provides an FRP composite sculpture body 10, which is prepared by the FRP composite sculpture body processing technology described in any of the above embodiments. It can be understood that the FRP composite sculpture body includes an FRP shell component 100 and a reinforcement component 200, and the FRP shell component 100 includes a first FRP shell 110 and a second FRP shell 120, and the first FRP shell 110 and the second FRP shell 120 are connected to form a cavity 130. The reinforcement component 200 includes a skeleton 210 and a first FRP fixing layer 220, and the skeleton 210 is arranged in the cavity 130, and the first FRP fixing layer 220 is formed on the skeleton 210 and connected to the side wall of the cavity 130.

[0098] The above-mentioned FRP composite sculpture body 10, since the first FRP shell 110 and the second FRP shell 120 both have the characteristics of good structural strength and lightness, can ensure that the FRP composite sculpture body 10 is obtained. The first FRP shell 110 and the second FRP shell 120 are connected to form a cavity 130, so that the reinforcement component 200 can be accommodated in the cavity 130, thereby avoiding the skeleton 210 and the first FRP fixing layer 220 being exposed on the FRP shell component 100, which makes the skeleton 210 easy to fall off, so that the shell component can play a better protective role for the skeleton 210. Furthermore, by adding the skeleton 210 in the cavity 130 and fixing the skeleton 210 on the side wall of the cavity 130 with the first FRP fixing layer 220, the skeleton 210 can be fixed in the cavity 130. In this way, the skeleton 210 inside the FRP composite sculpture body 10 can be improved. The structural strength of the side wall of the cavity 130 can avoid the phenomenon that the frame 210 is easy to fall off, that is, a FRP composite sculpture body 10 with good structural strength, lightness and high flatness can be obtained.

[0099] The present application also provides a display device, comprising the FRP composite sculpture body 10 described in any of the above embodiments, so that the FRP composite sculpture body 10 can provide different visual display effects for the display device.

[0100] Compared with the prior art, the present invention has at least the following advantages:

[0101] The above-mentioned FRP composite sculpture body processing technology can form a first FRP shell and a second FRP shell respectively inside the first mold base and the second mold base by making FRP inside the first mold base and the second mold base respectively, thereby providing a support structure for the appearance of the FRP composite sculpture body, that is, providing a better support effect for the subsequent skeleton, and then placing the skeleton at a preset position of the first FRP shell, and making FRP on the skeleton, so that the first FRP fixing layer can fit on the surface of the skeleton and can be bonded to the first FRP shell, so that the connection strength between the skeleton and the first FRP shell can be enhanced, and then the first mold base and the second mold base are closed, so that the skeleton can be covered in the first FRP shell and the second FRP shell, effectively avoiding the phenomenon that the skeleton is easily caused to fall off by external force, and finally the demolding operation is performed to obtain the FRP composite sculpture body, thereby completing the processing of the FRP composite sculpture body. By adopting the above processing technology, during the production of FRP, the liquid FRP resin is convenient for the user to brush the formed first mold base, the second mold base and the skeleton to obtain the first FRP shell, the second FRP shell and the first FRP fixing layer. Since the FRP resin of the first FRP fixing layer can flow into the first FRP shell, when the liquid FRP resin is cooled and solidified, the first FRP shell and the first FRP fixing layer can be adhered together, so that the skeleton can be fixed on the first FRP shell, thereby avoiding the phenomenon that the skeleton of the FRP composite sculpture is easy to fall off when in use, and ensuring that the FRP composite sculpture with good structural strength is obtained.

[0102] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
