Abstract

The invention is applicable to the technical field of materials, and provides a high-strength fiber composite material applicable to a marine bionic fishing environment and a preparation method and application of the high-strength fiber composite material. The composite material comprises a mixed fiber non-woven fabric layer and a coating layer coated on the surface of one side or the surfaces oftwo sides of the mixed fiber non-woven fabric layer, wherein the mixed fiber non-woven fabric layer is prepared by taking engineering fibers such as aramid fibers, ultra-high molecular weight polyethylene fibers, carbon fibers and polyphenyl ether as main raw materials and adding nano fluorocarbon, and the obtained composite material can be used for preparing marine fishing equipment and aquaculture equipment such as fishing nets and net cages. Compared with an existing wood structure net cage, the composite material has the obvious breaking strength advantage and has excellent wear resistance, weather resistance, corrosion resistance and stormy wave resistance, and the service cycle is long.

Description

technical field [0001] The invention belongs to the field of material technology, and in particular relates to a high-strength fiber composite material suitable for a marine imitation ecological fishing environment, a preparation method and application thereof. Background technique [0002] Deep-sea aquaculture cage refers to the aquaculture cage that can be used in relatively deep sea areas (usually the depth of the sea area is greater than 20m), and it is aquaculture equipment that has developed rapidly in the past ten years. In the past two decades, large-scale deep-sea cage culture represented by Norway has developed rapidly and continuously all over the world, and has achieved remarkable results. It is considered to be the most successful model of mariculture. In addition, Chile, Scotland, Canada, Greece, Turkey, Spain, Australia and other countries have also achieved greater success. [0003] However, the overall technical level of seawater cage culture in my country ...
