Abstract

The invention relates to an anti-stick composite fiber material, and belongs to the field of spinning. The anti-stick composite fiber material is composed of a fiber layer and an anti-stick layer, wherein the anti-stick layer is located on at least one surface of the fiber layer; and the fiber layer is prepared by the following steps: interweaving warp yarn fibers and weft yarn fibers to form fiber cloth, immersing the obtained fiber cloth into liquefied thermosetting resin, and solidifying, wherein the warp yarn fibers and the weft yarn fibers are selected from the following fibers: carbon fibers, mullite fibers, glass fibers and ceramic fibers, and the thermosetting resin is unsaturated polyester, epoxy resin or phenolic resin. According to the anti-stick composite fiber material, sticking between resin matrix materials can be prevented; and the anti-stick composite fiber material is convenient to store and use.

Description

technical field [0001] The invention relates to an anti-adhesive composite fiber material, which belongs to the field of spinning. Background technique [0002] Resin-based composites are fiber-reinforced materials based on organic polymers, usually using fiber reinforcements such as glass fibers, carbon fibers, or aramid fibers. Resin-based composites are widely used in aviation, automotive, and marine industries. However, when the resin-based material is stored, especially when it is rolled, long-term storage will cause adhesion between layers of materials, making it difficult to store. Contents of the invention [0003] The object of the present invention is to provide an anti-adhesive composite fiber material, which can prevent the adhesion between resin-based materials and is convenient for storage and use. [0004] An anti-adhesive composite fiber material, the material is composed of a fiber layer and an anti-adhesive layer positioned on at least one surface of th...
