Problems solved by technology

[0002] Solid rocket motors usually use traditional rubber-based insulation materials. In order to solve the problem that the material decomposes while peeling off and cannot form a carbonized layer of the material, a fixed-length carbon fiber (tile) reinforced phenolic modified nitrile rubber insulation material and braided carbon fiber have been developed. Reinforced phenolic modified nitrile rubber insulation material
This type of material has superior performance, but its matrix material is a polar system. Although transitional resins can be used to achieve bonding with carbon fibers, there is always an incompatible chemical interface, and the internal free substances are easy to migrate to the interface. , forming a phenomenon of enrichment and causing damage to the interface
Thus affecting the quality and service life of the product

Abstract

The invention discloses a carbon fiber reinforced ethylene-propylene-diene monomer rubber anti-ablation material and a preparation method. The anti-ablation material is prepared from: by weight, 15-30 parts of ethylene-propylene-diene monomer rubber matrix material, 45-50 parts of carbon fiber, and 20-32 parts of phenolic resin. The preparation method includes crushing the matrix material into small pieces, dissolving the material with a solvent to prepare a glue solution, adding the phenolic resin into the glue solution according to the ratio, stirring the mixture fully, distributing the obtained glue solution on the each part of the carbon fiber material uniformly, and air-drying the material. The carbon fiber reinforced ethylene-propylene-diene monomer rubber anti-ablation material can overcome the problems of compatibility and migration, can improve the quality, and can prolong the service life.
