Glass fiber-aramid fiber mixed fabric and production method thereof

Abstract

The invention relates to glass fiber-aramid fiber mixed fabric and a production method thereof. The glass fiber-aramid fiber mixed fabric comprises warp fiber bundles, weft fiber bundles and chopped strands, wherein the warp fiber bundles and the weft fiber bundles are uniformly distributed respectively; the warp fiber bundles and the weft fiber bundles are mutually staggered in a crossing way and are laminated; a layer of chopped strands is uniformly scatted between the warp fiber bundles and the weft fiber bundles; the warp fiber bundles are large-strand aramid fibers; the weft fiber bundles are large-strand glass fibers; the warp fiber bundles, the weft fiber bundles and the chopped strands are woven into fabric in a warp knitting and binding way. The conventional technology that single glass fibers are woven into fabric is changed, and by the production method, the warp fiber bundles, the weft fiber bundles and the chopped strands are woven into a low-cost and high-toughness complex structure in a warp knitting and binding way, so that the glass fiber-aramid fiber mixed fabric has both rigidness and flexibility and is impact-resistant; through arrangement of the chopped strands, the impregnating speed during impregnation of a finished product is greatly improved.

Description

technical field [0001] The invention relates to the field of composite fabrics, in particular to aramid fiber and glass fiber blended fabrics used in ships and protective materials, and in particular to a glass fiber and aramid blended fabric and a production method thereof. Background technique [0002] Glass fiber is made of glass balls or waste glass through high-temperature melting, drawing, winding, weaving and other processes. It is a very good metal substitute material. It is used in construction, ships, chemical pipelines, automobiles, aviation, wind Power generation and other fields have broad application prospects, and its application fields are still expanding, and the global market space is huge. The traditional glass fiber is a single FRP product, which is only rigid but not flexible, not impact resistant, and not tough enough. Although FRP is strong, its material is relatively brittle. Contents of the invention [0003] In view of the above technical problem...

AI Technical Summary

Problems solved by technology

[0003] In view of the above technical problems, the purpose of the present invention is to provide a glass fiber and aramid blended fabric, which changes the shortcomings of the previous single glass fiber products that are only rigid, relatively brittle, and easy to damage, and can obtain a low-cost and high-toughness composite structure
