Carbon-fiber fabric composite material complete vehicle frame and preparation method thereof

Abstract

The invention discloses a carbon-fiber fabric composite material complete vehicle frame. The carbon-fiber fabric composite material complete vehicle frame is prepared from a three-dimensional frame, which is prepared by splicing carbon-fiber fabric composite material honeycomb tubes supported by carbon-fiber fabric composite materials in an annular shape; interior supports of the honeycomb tubes are star-like supports; annular supporting frames are in honeycomb holes of the star-like supports in the honeycomb tubes; and the annular supporting frames consist of winding tubes or weaving tubes. According to the carbon-fiber fabric composite material complete vehicle frame, tubular structural parts of the honeycomb-like supports prepared by using the carbon-fiber fabric composite materials arespliced with joints to form the complete vehicle frame; therefore, when the vehicle frame is stressed, the stress on the vehicle frame can be distributed to each branch of the honeycomb shape and canbe uniformly distributed on the structural part to enhance the integral stress level of the structural part; and as the support of the structural part is honeycomb-shaped, the material and weight ofthe structural part are reduced when being compared with the material and weight of a solid structural part, the cost is saved, and the structural part realizes stronger stress capability when being compared with the solid structural part.

Description

technical field [0001] The invention relates to the technical field of application of carbon fiber fabric composite materials, in particular to a vehicle frame made of carbon fiber fabric composite materials and a preparation method thereof. Background technique [0002] With the rapid development of modern technology, higher requirements are put forward for materials. Carbon fiber has the characteristics of high strength, high temperature resistance, corrosion resistance, fatigue resistance, light weight, and ability to withstand large tensile forces, which are significantly higher than steel and aluminum. It is a typical high-performance fiber and has overwhelming advantages over traditional metal materials. In addition to being used alone as a thermal insulation material, carbon fiber is usually added to resin, metal, ceramics, concrete and other materials as a reinforcing material to form carbon fiber composite materials. Carbon fiber composite materials have begun to be...
