▎ 摘　　要

NOVELTY - Epoxy resin composite material comprises component A and component B that are compounded with each other. The component A includes 40-45 pts. wt. epoxy resin, 3-5 pts. wt. preservatives, 1-5 pts. wt. ultra-fine light calcium carbonate powder, 4-10 pts. wt. graphene, 12-15 pts. wt. silica aerogel particles, 12-15 pts. wt. nano hollow ceramic beads, 5-8 pts. wt. expanded perlite, 6-10 pts. wt. dolomite, 10-12 pts. wt. glass fiber, 5-6 pts. wt. dispersant, 2-4 pts. wt. thickener, and 5-10 pts. wt. carbon fiber. The component B is a carbon fiber mixed cloth woven from carbon fiber threads, glass fiber threads, and insulating fibers. USE - Epoxy resin composite material used in a composite material field. ADVANTAGE - The epoxy resin composite material containing polyamide coating solves the problem of poor toughness in the background technology and complex processing technique, and improves the comprehensive mechanical property of the carbon fiber epoxy resins composite material at the same time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing epoxy resin composite material containing a polyamide coating, which involves firstly injecting ultrafine light calcium carbonate powder, dispersant, thickener, and an appropriate amount of water into the reactor, starting the mixer under stirring for 30-40 minutes, adding silica aerogel particles, nano hollow ceramic microbeads, dolomite, expanded perlite, graphene, glass fiber, and carbon fiber, adding epoxy resin and preservative under stirring for 20 minutes, putting the material into the pressed sheet material for standby, and mixing the carbon fiber thread and the glass fiber thread to form a warp thread.
