▎ 摘　　要

NOVELTY - Fluorine-containing composite material comprises 30-90 pts. wt. polytetrafluoroethylene resin, 5-20 pts. wt. carbon fiber, 2-3 pts. wt. chromium sesquioxide, and 1-5 pts. wt. graphene fluoride. USE - The fluorine-containing composite material is useful in radiation environment, and preparing aviation composite material or peripheral equipment of nuclear power plants (claimed). ADVANTAGE - The fluorine-containing composite material: has good radiation-resistant performance, after radiation, and can keep good wear-resistant and anti-wear performance; enhances the mutual attraction of the metal ion and the metal friction pair; reduces polytetrafluoroethylene composite material wear rate; and improves the anti-wear performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the fluorine-containing composite material, comprising, (i) taking the above-mentioned components and premixing to obtain a premix, and (ii) drying, stirring, and cold-pressing the premix, and then molding at high-temperature to obtain the fluorine-containing composite material.
