Description

technical field [0001] The invention relates to a carbon fiber composite material and a preparation method thereof, in particular to a composite transmission shaft with functionalized graphene modified resin as a matrix and wound with different grades of carbon fibers and a preparation method thereof. Background technique [0002] Traditionally, the transmission shafts of automobiles are mostly made of metal materials. Metal transmission shafts have many advantages, such as good toughness and high yield strength, but they also have many disadvantages, such as heavy weight, poor corrosion resistance, and non-renewable. Automobile lightweight is an urgent requirement for the promotion and use of new energy vehicles. The use of new materials with high specific modulus and specific strength is an effective measure for automobile weight reduction. Carbon fiber composite materials have the advantages of light weight, large specific modulus, high specific strength, and small therma...
