Abstract

The invention provides an automobile-cantilever-beam supporting system. The automobile-cantilever-beam supporting system comprises an automobile-cantilever-beam supporting rod piece and an automobile-cantilever-beam supporting fixing end. The automobile-cantilever-beam supporting rod piece is prepared from, by weight, 300-3,500 parts of reinforced fibers, 1,000-1,200 parts of caprolactam, 0.001-10 parts of an activating agent and 0.002-10 parts of a catalyst; the automobile-cantilever-beam supporting fixing end is prepared from, by weight, 1,000-1,200 parts of caprolactam, 0.001-10 parts of an activating agent and 0.002-10 parts of a catalyst. According to the automobile-cantilever-beam supporting system, the specific-ratio reinforced fibers, caprolactam, activating agent and catalyst are used as the supporting rod piece in cooperation with the specific-ratio supporting fixing end, and therefore the automobile-cantilever-beam supporting system is prepared. Nonmetal is used as a raw material, the obvious lightweight effect is achieved, and meanwhile the mechanical performance and the anti-fatigue performance are better.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile cantilever beam support system and a preparation method thereof. Background technique [0002] With the global shortage of resources and climate warming, limiting carbon emissions is an effective means to slow down the depletion of global oil energy and the deterioration of the natural ecological environment. Especially in the automobile industry, in response to consolidating and improving the future international competitiveness of the automobile industry, developed countries such as Europe, America and Japan are taking active measures to promote and promote the development of automobile energy-saving technology and improve the fuel economy level of automobiles. China has also started the work of reducing vehicle emissions, but China's task is quite severe. Commercial vehicles will implement National V emission standards by 2016. In order to achieve the emissi...
