[0013] Example 1

[0014] A kind of composite material rapid prototyping production device of this embodiment, such as figure 1 As shown, it includes a loom frame (not shown in the figure), and an ultraviolet light emitter 1 and a light-curing 3D printer 3 are sequentially installed on the loom frame from top to bottom; the light-curing 3D printer 3 The inner bottom surface is a liquid storage tank 10; the above left and right inner walls of the photo-curing 3D printer 3 are respectively provided with a row of horizontal pick-up holes 6 at the same height; the photo-curing 3D printer 3 is above the front and rear inner walls The same height is provided with a row of vertical pick-up holes 2 respectively; The passing weft inserter is located at the same height; the inner bottom surface of the liquid holding tank 10 below the horizontal direction picking hole 6 and the vertical direction picking hole 2 is equipped with a lifting device 5 made of an electric motor and a threaded rod. A printing platform 9 is installed on the lifting device 5 made of the electric motor and threaded rod, and the printing platform 9 is also located below the horizontal direction picking hole 8 and the vertical direction picking hole 2; the light A flat mirror 4 is respectively installed on the inner wall surface around the top of the curing 3D printer 3 . Moreover, the four plane mirrors 4 can make the light source project the same shape and coincident projections on the printing platform 9, so as to avoid shadows in the illumination range.

[0015] A preparation method for rapid prototyping of composite materials in this embodiment includes the following steps: first, put liquid UV photosensitive resin into the liquid tank 10 of the photocurable 3D printer 3, and use the electric motor and threaded rod to manufacture The completed lifting device 5 controls the height of the printing platform 9 so that the photosensitive resin liquid immerses the height of a layer on the upper surface of the printing platform 9; A device (not shown in the figure) passes the warp yarn 8 through a row of vertical picking holes 2 on the light-curing 3D printer 3, and then uses the glass fiber yarn on the weft yarn barrel (not shown in the figure) on the loom to pass through The weft insertion device (not shown in the figure) passes the weft yarn 7 through a row of horizontal picking holes 6 on the light-curing 3D printer 3, and the drawn weft yarn 7 passes through the warp yarn 8 according to the plain weave rule of one up and one down to form a mutual Interwoven woven plain weave structure; the photocuring 3D printer 3 uses the ultraviolet light emitter 1 to print the model layer by layer according to the model designed by the model software, wherein the shape of each slice is the ultraviolet light The shape projected by the emitter 1 onto the printing platform 9 of the 3D printer, and the intersecting movement between the printing work and the yarns are continuously repeated, and the superimposed liquid UV photosensitive resin and interwoven yarns will be continuously solidified on the printing platform 9 , so that the interwoven yarns are continuously distributed in the uncured liquid UV photosensitive resin; wherein each layer of slices is printed using the lifting device 5 made of the electric motor and threaded rod to descend to ensure that there is only one layer on the printing platform Slice-thick liquid UV photosensitive resin. The cyclic and repeating method of the printing work and the mutual intersecting movement between the yarns is as follows: the mutual intersecting movement of the warp and weft yarns is completed during the interval of the 3D printing work.

[0016] Because in this embodiment, when the ultraviolet light emitter 1 projects light and shadow to the printing platform 9, the glass fiber warp yarn 8 resistant to strong light will block a part of the projected light and shadow, which will cause a part of the liquid UV photosensitive resin to be difficult to be illuminated and cannot be cured. Therefore, four smooth plane mirrors 4 are used to reflect a part of the light on the printing platform 9, so as to ensure that the liquid UV photosensitive resin is completely irradiated and cured. At the same time, the intermittent period of light curing is used to complete the upper and lower interaction between warp and weft yarns. Cross movement, so that the yarn can be evenly distributed in the uncured photosensitive resin.

[0017] In this embodiment, a composite material rapid prototyping production device and preparation method combined with a woven plain weave structure uses a 3D printer in the form of light curing (SLA) to disperse high-strength yarns into the uncured in photosensitive resin. This method effectively solves the problem of insufficient strength of the photosensitive resin after molding, so that the mechanical properties of the molded parts are better enhanced; while not affecting the normal operation of the photocuring 3D printer, it also makes full use of the 3D printer from model design to product. The rapid prototyping method of production not only meets people's convenient design concept from product design to rapid prototyping, but also meets the individual needs of products; it also improves the mechanical properties of products, and shortens the production time compared with traditional composite material processing methods. cycle, reducing the production process of the product. Secondly, this embodiment makes full use of the excellent performance of high-strength yarn, so that the designed product has the characteristics of high strength while ensuring the appearance and appearance, which greatly enriches the scope of application of 3D printing technology and breaks through the application of 3D printing technology in The limitations that cannot be used in medical, aerospace and other fields have great practical significance.

Form an interwoven plain weave structure; the photocuring 3D printer 3 uses the ultraviolet light emitter 1 to print the model in a layer-by-layer printing manner according to the model designed by the model software, wherein the shape of each slice is the described The ultraviolet light emitter 1 is projected onto the shape on the printing platform 9 of the 3D printer, and the intersecting movement between the printing work and the yarn is repeated continuously, and the superimposed liquid UV photosensitive resin and the interwoven fabric will be continuously solidified on the printing platform 9 yarn, so that the interwoven yarn is continuously distributed in the uncured liquid UV photosensitive resin; where each layer of slice is printed using the lifting device 5 made of the electric motor and threaded rod to descend to ensure that only Liquid UV photosensitive resin with a slice thickness.
