Problems solved by technology

[0002] With the continuous improvement of weapon systems and aircraft requirements for solid rocket motors, the requirements for the comprehensive performance of the heat insulation layer have increased to unprecedented heights, and conventional rubber-type heat insulation materials cannot meet the requirements of design indicators. Therefore, materials with high impact resistance Came into being
There are mainly fiber-woven reinforced rubber-based composite materials, surface ceramic materials, etc. Although the material performance has been improved to a new level, the material cost has also increased by an order of magnitude.

Abstract

The invention discloses a carbon felt-enhanced phenolic aldehyde ethylene propylene diene monomer-based thermal insulation material and a preparation method thereof. The thermal insulation material is prepared from the following raw materials in parts by weight: 15-30 parts of an ethylene propylene diene monomer matrix material, 10-30 parts of phenolic resin and 45-60 parts of carbon felt, wherein the carbon felt is a protofilament carbon felt, carbon filament carbon felt or pre-oxidized fiber carbon felt. The thermal insulation material is prepared through matrix material preparation, resin dissolving, glue dipping and after-treatment; the raw materials are of a felt-structured carbon fiber enhanced system, so that the cost can be lowered while the performance is guaranteed; and by utilizing a three-section roll-in glue dipping process, the glue content uniformity of the product is obviously increased.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials in combustion chambers of solid rocket motors, and in particular relates to a carbon felt reinforced phenolic EPDM rubber-based thermal insulation material and a preparation method thereof. Background technique [0002] With the continuous improvement of weapon systems and aircraft requirements for solid rocket motors, the requirements for the comprehensive performance of the heat insulation layer have increased to unprecedented heights, and conventional rubber-type heat insulation materials cannot meet the requirements of design indicators. Therefore, materials with high impact resistance Came into being. There are mainly fiber-woven reinforced rubber-based composite materials, surface ceramic materials, etc. Although the material performance has been improved to a new level, the material cost has also increased by an order of magnitude. Therefore, further reducing the cost ...
