Title:
POLYTRICYCLOPENTADIENE (PTCPD) FIBER COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/170639
Kind Code:
A1
Abstract:
Disclosed in the present invention is a polytricyclopentadiene (PTCPD) fiber composite material and a preparation method therefor. The composite material comprises: a PTCPD resin system, and fibers and/or fiber fabrics, the fibers and/or fiber fabrics being compositely connected to the PTCPD resin system. By modifying the fiber surface, the content of active groups on the fiber surface is increased, and the bonding ability between the fibers and PTCPD interfaces is improved. The method of modifying the fiber surface comprises: coating the fiber surface with a sizing agent, treating the fiber surface with a coupling agent, etching the fiber surface, or a combination thereof. The PTCPD fiber composite material provided by the present invention solves the technical problem of insufficient rigidity of polydicyclopentadiene (PDCPD) composite materials in the prior art, and has the advantages such as high strength, low dielectric constant, light weight, low cost, and high corrosion resistance.
