Vertical core material woven fabric

Abstract

The invention discloses a vertical core material woven fabric which is formed by connecting a first fabric layer and a second fabric layer through stand supporting core column filaments, wherein the first fabric layer and the second fabric layer are woven through warps and wefts made of inorganic nonmetallic materials. The stand supporting core column filaments for connecting the first fabric layer and a second fabric layer are connected in continuous W shapes along the weft direction and are connected in a staggered and intersected mode and in double X shapes along the warp direction. The stand supporting core column filaments and warp-wise connection points and weft-wise connection points of the first fabric layer and the second fabric layer respectively form a plurality of connection nodes nearby, and the plurality of connection nodes are positioned on the planes of the first fabric layer and the second fabric layer in staggered queue type distribution vertically and correspondingly. The vertical core material woven fabric has the advantages of being reasonable and advanced in structure, capable of serving as the core material to manufacture hollow glass fiber reinforced plastic products, relatively simple in process, high in production efficiency, good in quality of manufactured goods and the like.

Description

technical field [0001] The invention relates to a woven fabric, in particular to a three-dimensional core material woven fabric used for multi-axial support and standing of the reinforced core material of glass fiber reinforced plastic parts. Background technique [0002] The three-dimensional core material woven fabric of the present invention is a kind of reinforced core material mainly used for hollow fiberglass products. [0003] FRP parts are composite parts made of resin and reinforced core glass fiber or glass fiber woven fabric. FRP parts are widely used in manufacturing fields such as tanks for storage or transportation of liquid substances, building components, nacelle covers, partitions and bottom floors of traffic vehicles and ships, and wind blades for wind power generation. Industrial products of "replacing steel with plastic". [0004] Most of the preparation methods of FRP products in the prior art still use manual implementation as the main method. After ...

AI Technical Summary

Problems solved by technology

[0007] And the lodging of this three-dimensional fabric core of said patent is a common problem of existing three-dimensional fabric cores

When adopting this three-dimensional fabric core that is easy to fall to prepare hollow FRP products, it is not necessary to artificially help this three-dimensional fabric core to stand up in the production process, and to coat resin on the surface of the three-dimensional fabric core, which undoubtedly increases It increases the complexity of the operation, and at the same time it is difficult to guarantee the shape, size and quality of FRP products
