Abstract: Mechanical, hydrothermal, flame retardant and fire protection performance of high heat resistant and flame retardant epoxy resin matrix CFRP is investigated in this article. The results show that the high heat resistant and flame retardant CFRP has great mechanical and flame retardant performance. The flame retardant epoxy resin matrix CFRP has achieved a flame retardant grade of V-0. Its maximum smoke density (Dm) within 240 seconds is 5.17, and its limiting oxygen index (LOI) is 39.5%. Therefore, this material can basically meet airworthiness standard. Above all, research on properties of structural and functional integrated CFRP lays a foundation for the final engineering application in advance aero-craft and aero-engine.

Key words: CFRP, epoxy resin, flame retardant, mechanical performance
