汽车材料的应用现状与发展趋势探讨

For the sake of satisfying people’s ever increasing demands on the environmental protection, energy saving, safety, and comfort about automobile,great changes have taken place in the automative materials.Vehicle mass reduction has become one of the developing trends of automobile. This paper intruduces and analyses the organizations,elements,physical characteristics and molding process of steel materials,light alloy materials,plastic,ceramic materials,composite materials and other materials used in automobile.And it points out the effects of them in decreasing automobile weight,reducing the exhaust gas,deceasing energy consumption,increasing security and integrated capabilities. And the paper intruduces briefly the application situation in automobile manufacture.This paper indicates the developing trends of automative materials. Those trends are as follows: steel materials are steel the main parts in automative materials,but the capabilities will be increasing,and the propotion will be decreasing,. Light alloy materials,plastic,ceramic materials,composite materials and other materials will be increasing in automative materials.
