Abstract

The invention provides a silicone resin composition for prepregs, a carbon fiber prepreg and a carbon fiber-silicone resin composite material, relating to a silicone resin composition, a carbon fiber prepreg prepared from the silicone resin composition and a silicone resin composite material. The invention aims to solve the problems of poor high-temperature resistance and single function in the existing silicone resin-carbon fiber composite material. The composition comprises the silicone resin, a phenolic resin, a toughener, a functional filler, a coupling agent and a catalyst. The carbon fiber prepreg comprises a carbon fiber material and the composition for prepregs. The carbon fiber-silicone resin composite material is prepared by curing the carbon fiber prepreg. The curing method comprises winding molding, cast molding or compression molding. The carbon fiber prepreg is cured to obtain the carbon fiber composite material. The carbon fiber composite material has favorable mechanical properties and high-temperature resistance. The silicone resin composition is applicable to the field of silicone resin-carbon fiber composite materials.

Description

technical field [0001] The invention relates to a silicone resin composition, a carbon fiber prepreg and a silicone resin composite material using the silicone resin composition as raw materials. Background technique [0002] Because aerospace works at high altitude and high speed, the external materials of the machine are required to have better high temperature resistance, low temperature resistance, and ozone resistance. The development and needs of the aerospace industry have promoted the development of advanced composite materials, and the development and application of advanced composite materials have promoted the progress of aerospace. With the widespread use of advanced composite materials in the aerospace field, new requirements are put forward for the performance of composite materials. Composite materials are required to have high specific strength, high specific modulus, high temperature resistance, low temperature resistance, and ozone resistance. Aerospace p...
