摘要

Abstract—The deformation and failure of two types of three-layer metallopolymer composites have been analyzed. The outer layers of these composites are thin sheets of VT23 high-strength titanium alloy, and the inner layers are made of carboplastic or organic plastic. Failure staging of laminated composites has been considered. The properties of the composites have been compared from specific characteristics, namely, from ratios of strength parameters and Young modulus to specific weight. It has been shown that the load-carrying capacity of the composite consisting of highest specific strength materials (titanium + carboplastic) may be lower than that of the composite with high deformation performance (titanium + organic plastic).
