Abstract: The main methods and techniques to achieve light-weight design of structures by using fiber-reinforced polymer composites (FRP) are analyzed and summarized in this paper. Main methods to achieve light-weight design of structures have been pointed out. The first is to develop new FRP with higher mechanical priperties, that is, to further improve the specific strength and modulus of the FRP to achieve further weight save. The second is optimized design for the configuration of the bearing structures, that is, to achieve further weight save by the optimized scheming of the carrying capacity and stress transferring paths of FRP. The third is the integral manufacturing of composite structures with complex configurations, that is, to achieve further weight save by abandoning the extra joint components. Technical approaches to achieve the above three methods of light-weight design are also discussed.

Key words: fiber-reinforced polymer composites, structure design, light-weight design, mechanical property, fabrication technique
