Description

Technical Field

[0001] The present invention relates to the technical field of wood-based materials, and specifically to a manufacturing method of a carbon fiber wood-based composite material. Background Art

[0002] First, in order to increase the strength of wood-based boards, the strength of wood-based boards can be increased to a certain extent by attaching carbon fibers. The most common method is to attach a woven carbon fiber mesh or carbon fiber cloth to the surface of the wood-based board. By surface-treating the carbon fibers and then through an adhesion method, one or more reinforcing layers are formed on the wood-based board. However, this method still has defects. First, the reinforcing layer is located on the surface of the wood-based board, and the interlayer strength of the wood-based board is not strengthened. Since the reinforcing layer is on the surface, the strength at the center of the wood-based board remains unchanged. Therefore, this kind of reinforcement method is not comprehensive. Summary of the Invention

[0003] The purpose of the present invention is to provide a manufacturing method of a carbon fiber wood-based composite material to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution:

[0005] A manufacturing method of a carbon fiber wood-based composite material, comprising: S1: Feeding broken wood and wood chips into a mill to crush the broken wood and wood chips, and feeding the crushed wood chips into a drying furnace to dry until the humidity drops to 1.5%. After screening and separation by a screening machine, glue and a chemical hardness agent are combined and mixed with the screened wood chips to obtain intermediate wood chips and surface wood chips;

[0006] S2: Interlacing horizontal carbon fiber strips and vertical carbon fiber strips to form an intermediate carbon fiber woven surface. Both the front and back sides of the horizontal carbon fiber strips are fixedly connected with vertically staggered carbon fiber reinforcing bundles, and both the front and back sides of the vertical carbon fiber strips are fixedly connected with horizontally staggered carbon fiber reinforcing bundles. Then, the vertical carbon fiber reinforcing bundles and the horizontal carbon fiber reinforcing bundles are passed through an intermediate pressing mold and fixedly connected to the surface of a traction plate. By pulling outward with two traction plates, a space is formed at the seam of the intermediate carbon fiber woven surface;

[0007] S3: Filling and tamping the intermediate wood chips between the two intermediate pressing molds, and filling the intermediate wood chips into the space at the seam of the intermediate carbon fiber woven surface. By applying pressure with the two intermediate pressing molds, the intermediate wood chips and the intermediate carbon fiber woven surface are successively cold-pressed and hot-pressed and activated to prepare a board intermediate;

[0008] S4: Separate the traction plate from the longitudinal carbon fiber reinforcement bundle and the horizontal carbon fiber reinforcement bundle, separate the intermediate pressing mold from the plate intermediate. The two adjacent longitudinal carbon fiber strips at the same Z-axis position are woven and connected in the X direction by the two horizontal carbon fiber reinforcement bundles, and the two adjacent horizontal carbon fiber strips at the same Z-axis position are woven and connected in the Y direction by the two longitudinal carbon fiber reinforcement bundles, so that the surface of the plate intermediate forms a surface body carbon fiber reinforcement surface through the weaving of the longitudinal carbon fiber reinforcement bundle and the horizontal carbon fiber reinforcement bundle;

[0009] S5: Fill equal amounts of the surface body wood chips on both sides of the plate intermediate. After sequentially performing cold pressing forming and hot pressing activation processes on both sides of the plate intermediate through the surface body pressing mold, a plate surface body surrounding the surface body carbon fiber reinforcement surface is formed on the outer layer of the plate intermediate, completing the preparation process of the carbon fiber wood-based composite material, and then transferring to the surface decoration process for appearance deep processing.

[0010] As a further scheme of the present invention: The intermediate pressing mold is provided with a profiling groove body only for passing through the longitudinal carbon fiber reinforcement bundle and the horizontal carbon fiber reinforcement bundle.

[0011] As a further scheme of the present invention: The horizontal carbon fiber strip and the longitudinal carbon fiber strip are strip structures formed by weaving multiple fiber filaments. The longitudinal carbon fiber reinforcement bundle and the horizontal carbon fiber reinforcement bundle are composed of multiple un-woven carbon fiber filaments linearly distributed. The length of the longitudinal carbon fiber reinforcement bundle is consistent with the distance between two adjacent horizontal carbon fiber strips at the same Z-axis position, and the length of the horizontal carbon fiber reinforcement bundle is consistent with the distance between two adjacent longitudinal carbon fiber strips at the same Z-axis position.

[0012] As a further scheme of the present invention: The longitudinal carbon fiber reinforcement bundle and the horizontal carbon fiber reinforcement bundle are divided into two bundles, and are respectively woven and connected with the corresponding longitudinal carbon fiber reinforcement bundle and horizontal carbon fiber reinforcement bundle.

[0013] As a further scheme of the present invention: On the X-Y plane, the long side of the horizontal carbon fiber reinforcement bundle has a ninety-degree angle with the long side of the longitudinal carbon fiber strip, and the long side of the longitudinal carbon fiber reinforcement bundle has a ninety-degree angle with the long side of the horizontal carbon fiber strip.

[0014] As a further scheme of the present invention: The longitudinal carbon fiber reinforcement bundle and the horizontal carbon fiber reinforcement bundle are detachably connected to the traction plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The combination of a three-dimensional structure formed by carbon fiber weaving and a compressed wood matrix material forms two surface reinforcements on the basis of central reinforcement, and there is also a reinforcement connection structure between the surface reinforcement and the central reinforcement, which is a three-dimensional reinforced carbon fiber network structure. This significantly improves the strength of the wood matrix material comprehensively, and the interlayer strength is also enhanced, solving the problem of insufficient interlayer structure strength in the connection between carbon fiber and the wood matrix.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Please refer to Figures 1-6 :

[0026] Including: S1: Feed shredded wood and wood chips into a mill to crush the shredded wood and wood chips, and feed the crushed wood chips into a drying furnace for drying until the humidity drops to 1.5%. Screen and separate them through a screening machine, combine glue and a chemical hardness agent, and mix them with the screened wood chips to obtain intermediate wood chips and surface wood chips;

[0027] First, the compressed wood board is mainly made of shredded wood and wood chips that are crushed and dried, and then mixed with glue and a chemical hardness agent and cold-pressed into shape, and the glue is activated through a hot-pressing process to form a board. Therefore, this method is mainly applied to the compressed wood board process, and by specially treating carbon fiber, the interlayer strength problem is solved. The volume of the intermediate wood chips is larger than that of the surface wood chips. This is mainly because after the volume of the surface wood chips shrinks, during subsequent compression, the surface graininess is lower than that of the intermediate wood chips, so the volume of the surface wood chips is smaller than that of the intermediate wood chips.

[0028] S2: Interweave the horizontal carbon fiber strips 1 and the longitudinal carbon fiber strips 2 to form an intermediate carbon fiber woven surface 100. Both the front and back sides of the horizontal carbon fiber strips 1 are fixedly connected with staggered longitudinal carbon fiber reinforcing bundles 11, and both the front and back sides of the longitudinal carbon fiber strips 2 are fixedly connected with staggered horizontal carbon fiber reinforcing bundles 21. Then, pass the longitudinal carbon fiber reinforcing bundles 11 and the horizontal carbon fiber reinforcing bundles 21 through an intermediate pressing die 3 and fixedly connect them to the surface of a traction plate 4. Pull outward through the two traction plates 4 to form a space at the seam of the intermediate carbon fiber woven surface 100. The intermediate pressing die 3 is provided with a profiling groove body only for passing through the longitudinal carbon fiber reinforcing bundles 11 and the horizontal carbon fiber reinforcing bundles 21;

[0029] First, the horizontal carbon fiber strips 1 and the longitudinal carbon fiber strips 2 are interwoven in the form of Figure 3 . The weaving density of the horizontal carbon fiber strips 1 and the longitudinal carbon fiber strips 2 is relatively low. At this time, the intermediate carbon fiber woven surface 100 is obtained by weaving in this way, and the intermediate carbon fiber woven surface 100 is located in the middle of the board intermediate 5. However, at this time, the intermediate carbon fiber woven surface 100 is still a planar structure. In order to prevent the intermediate carbon fiber woven surface 100 and the board intermediate 5 from having a delaminated structure, the longitudinal carbon fiber reinforcing bundles 11 and the horizontal carbon fiber reinforcing bundles 21 are provided.

[0030] First, the longitudinal carbon fiber reinforcement bundles 11 are distributed on the upper and lower surfaces of the horizontal carbon fiber strip 1, while the horizontal carbon fiber reinforcement bundles 21 are distributed on the upper and lower surfaces of the longitudinal carbon fiber strip 2. Since there is an overlapping area between the horizontal carbon fiber strip 1 and the longitudinal carbon fiber strip 2, the positions where the longitudinal carbon fiber reinforcement bundles 11 and the horizontal carbon fiber reinforcement bundles 21 are fixed on the horizontal carbon fiber strip 1 and the longitudinal carbon fiber strip 2 are staggered, thus avoiding the overlapping area. At this time, the longitudinal carbon fiber reinforcement bundles 11 and the horizontal carbon fiber reinforcement bundles 21 on both sides are fixed on the traction plate 4. Affected by the overlapping area, the traction plate 4 is pulled outward at this time, thus forming Figure 5 the shape shown. At this time, the area located between the overlapping areas is affected by the tensile force, and a large spacing change occurs in the Z-axis of the horizontal carbon fiber strip 1 and the longitudinal carbon fiber strip 2. And at this time, the space formed at the joint can accommodate the intermediate wood chips. At this time, the intermediate carbon fiber woven surface 100 inside the plate intermediate 5 is not a single-layer structure. At this time, the intermediate carbon fiber woven surface 100 and the plate intermediate 5 are cross-connected to increase the strength.

[0031] The longitudinal carbon fiber reinforcement bundles 11 and the horizontal carbon fiber reinforcement bundles 21 play an auxiliary role in the processing, but if the longitudinal carbon fiber reinforcement bundles 11 and the horizontal carbon fiber reinforcement bundles 21 are only set for auxiliary processing, the cost will increase. Therefore, in combination with the manufacturing processes of the compression plate intermediate and the surface body, the longitudinal carbon fiber reinforcement bundles 11 and the horizontal carbon fiber reinforcement bundles 21 are further utilized.

[0032] S3: Fill and compact the intermediate wood chips between the two intermediate pressing molds 3, and the intermediate wood chips are filled into the space at the joints of the intermediate carbon fiber woven surface 100. Apply pressure through the two intermediate pressing molds 3 to sequentially cold-press and hot-press and activate the intermediate wood chips and the intermediate carbon fiber woven surface 100 to prepare the plate intermediate 5;

[0033] First, the above describes the preparation process of the plate intermediate 5. Due to the existence of the longitudinal carbon fiber reinforcement bundles 11 and the horizontal carbon fiber reinforcement bundles 21, certain difficulties will occur when the plate intermediate 5 is pressed. Combining with the requirements of the intermediate wood chips, it is only necessary to open a groove at the intermediate pressing mold 3 that only allows the longitudinal carbon fiber reinforcement bundles 11 and the horizontal carbon fiber reinforcement bundles 21 to pass through. And at this time, the intermediate wood chips are relatively large, so when the groove presses the plate intermediate 5, the influence generated is very small, thus meeting the processing requirements.

[0034] S4: Separate the traction plate 4 from the longitudinal carbon fiber reinforcement bundle 11 and the horizontal carbon fiber reinforcement bundle 21, separate the intermediate body pressing die 3 from the plate intermediate body 5. Two adjacent longitudinal carbon fiber strips 2 at the same Z-axis position are woven and connected in the X direction by two horizontal carbon fiber reinforcement bundles 21, and two adjacent horizontal carbon fiber strips 1 at the same Z-axis position are woven and connected in the Y direction by two longitudinal carbon fiber reinforcement bundles 11, so that the surface of the plate intermediate body 5 forms a surface body carbon fiber reinforcement surface 200 through the weaving of the longitudinal carbon fiber reinforcement bundle 11 and the horizontal carbon fiber reinforcement bundle 21;

[0035] First, for the convenience of understanding, the directions are illustrated in the figure. Please refer to Figure 3 、 Figure 4 and Figure 5 . Since the horizontal carbon fiber strip 1 and the longitudinal carbon fiber strip 2 have an overlapping area, the Z-axis force-bearing strength of the intermediate body formed by the horizontal carbon fiber strip 1 and the longitudinal carbon fiber strip 2 is increased. The Z-axis force can be understood as two opposite forces perpendicular to the plate intermediate body 5 acting on both sides of the plate intermediate body 5. However, since the horizontal carbon fiber strip 1 and the longitudinal carbon fiber strip 2 have low force-bearing strength in the X and Y directions, the intermediate body carbon fiber woven surface 100 is further strengthened. First, please refer to Figure 3 . Due to the intersection of the horizontal carbon fiber strip 1 and the longitudinal carbon fiber strip 2, there is a Z-axis position difference between two adjacent longitudinal carbon fiber strips 2. However, two adjacent longitudinal carbon fiber strips 2 at the same Z-axis position can be woven and connected in the X direction by the horizontal carbon fiber reinforcement bundle 21. At this time, the strength between the two longitudinal carbon fiber strips 2 in the X direction is enhanced. Similarly, after the longitudinal carbon fiber reinforcement bundle 11 is woven and connected in the Y direction in an intersecting manner, the Y-direction strength is further increased. After the weaving is completed, please refer to Figure 4 . At this time, a surface body carbon fiber reinforcement surface 200 is formed on the surface of the plate intermediate body 5, and the surface body carbon fiber reinforcement surface 200 is also connected to the intermediate body carbon fiber woven surface 100 in the Z axis. At this time, two surface reinforcements are formed on the basis of the central reinforcement, and at the same time, a three-dimensional reinforced carbon fiber network structure with a reinforcement connection structure is also formed between the surface reinforcement and the central reinforcement. The strength of the wood matrix material is greatly improved comprehensively, and the interlayer strength is also enhanced.

[0036] S5: Fill equal amounts of surface body wood chips on both sides of the plate intermediate body 5. After sequentially performing cold pressing and hot pressing activation processes on both sides of the plate intermediate body 5 through the surface body pressing die 7, a plate surface body 6 surrounding the surface body carbon fiber reinforcement surface 200 is formed on the outer layer of the plate intermediate body 5, completing the preparation process of the carbon fiber wood matrix composite material, and then transferring to the surface decoration process for appearance deep processing;

[0037] At this time, in combination with the preparation of the compression plate, after the surface body carbon fiber reinforcement surface 200 is woven, it is closely attached to the surface of the plate intermediate body 5. At this time, the surface body wood chips are filled through the gap between the surface body pressing die 7 and the plate intermediate body 5, and then through the cold pressing and hot pressing processes. A plate surface body 6 is formed on the surface of the surface body carbon fiber reinforcement surface 200. In order to further increase the stability of the surface body carbon fiber reinforcement surface 200, when the surface body carbon fiber reinforcement surface 200 is woven, an adhesive can be coated on the contact surface between the surface body carbon fiber reinforcement surface 200 and the plate intermediate body 5 to increase the stability.

[0038] The horizontal carbon fiber strips 1 and the longitudinal carbon fiber strips 2 are strip-shaped structures formed by weaving multiple fiber filaments. The longitudinal carbon fiber reinforcement bundles 11 and the horizontal carbon fiber reinforcement bundles 21 are composed of multiple un-woven carbon fiber filaments distributed linearly. The length of the longitudinal carbon fiber reinforcement bundles 11 is the same as the Z-axis position and the spacing between two adjacent horizontal carbon fiber strips 1 is consistent. The length of the horizontal carbon fiber reinforcement bundles 21 is the same as the Z-axis position and the spacing between two adjacent longitudinal carbon fiber strips 2 is consistent. The longitudinal carbon fiber reinforcement bundles 11 and the horizontal carbon fiber reinforcement bundles 21 are divided into two bundles and are respectively woven and connected with the corresponding longitudinal carbon fiber reinforcement bundles 11 and horizontal carbon fiber reinforcement bundles 21;

[0039] First, the horizontal carbon fiber strips 1 and the longitudinal carbon fiber strips 2 can be woven into strips in advance. At this time, the longitudinal carbon fiber reinforcement bundles 11 and the horizontal carbon fiber reinforcement bundles 21 can be incorporated with fiber filaments on the basis of the weaving of the horizontal carbon fiber strips 1 and the longitudinal carbon fiber strips 2. At this time, the fiber filaments are perpendicular to the horizontal carbon fiber strips 1 and the longitudinal carbon fiber strips 2, and the longitudinal carbon fiber reinforcement bundles 11 and the horizontal carbon fiber reinforcement bundles 21 play a processing auxiliary role during the preparation of the plate intermediate body 5. After the plate intermediate body 5 is formed, at this time, the longitudinal carbon fiber reinforcement bundles 11 are woven with the longitudinal carbon fiber reinforcement bundles 11, and the horizontal carbon fiber reinforcement bundles 21 are woven with the horizontal carbon fiber reinforcement bundles 21. Since the longitudinal carbon fiber reinforcement bundles 11 and the longitudinal carbon fiber reinforcement bundles 11, and the horizontal carbon fiber reinforcement bundles 21 and the horizontal carbon fiber reinforcement bundles 21 are in parallel lines, in order to increase the weaving strength, auxiliary carbon fiber filaments in the transverse direction can also be added to weave the longitudinal carbon fiber reinforcement bundles 11 and the longitudinal carbon fiber reinforcement bundles 11, and the horizontal carbon fiber reinforcement bundles 21 and the horizontal carbon fiber reinforcement bundles 21 into strips.

[0040] On the X-Y plane, the long side of the horizontal carbon fiber reinforcement bundle 21 has a ninety-degree angle with the long side of the longitudinal carbon fiber strip 2, and the long side of the longitudinal carbon fiber reinforcement bundle 11 has a ninety-degree angle with the long side of the horizontal carbon fiber strip 1;

[0041] First, if the longitudinal carbon fiber reinforcement bundle 11 is parallel to the horizontal carbon fiber strip 1 and the horizontal carbon fiber reinforcement bundle 21 is parallel to the longitudinal carbon fiber strip 2, at this time, the connection of the longitudinal carbon fiber reinforcement bundle 11 and the longitudinal carbon fiber reinforcement bundle 11, and the horizontal carbon fiber reinforcement bundle 21 and the horizontal carbon fiber reinforcement bundle 21 on the surface body carbon fiber reinforcement surface 200 cannot supplement the strength in the X or Y direction. Therefore, when the long side of the horizontal carbon fiber reinforcement bundle 21 has a 90-degree angle with the long side of the longitudinal carbon fiber strip 2, and the long side of the longitudinal carbon fiber reinforcement bundle 11 has a 90-degree angle with the long side of the horizontal carbon fiber strip 1. After the surface body carbon fiber reinforcement surface 200 is woven, it has a certain ability to supplement the strength in the X and Y directions.

[0042] The longitudinal carbon fiber reinforcement bundle 11 and the horizontal carbon fiber reinforcement bundle 21 are detachably connected to the traction plate 4;

[0043] Since the longitudinal carbon fiber reinforcement bundle 11 and the horizontal carbon fiber reinforcement bundle 21 are only temporarily fixed to the traction plate 4, and the subsequent longitudinal carbon fiber reinforcement bundle 11 and horizontal carbon fiber reinforcement bundle 21 need to be continuously woven, the longitudinal carbon fiber reinforcement bundle 11 and the horizontal carbon fiber reinforcement bundle 21 can be fixed to the traction plate 4 by any detachable connection form such as a fixture or bonding.

[0044] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
