Abstract
A study is made of the connection between the fracture toughness of sh ock-resistant polymeric composites based on polycarbonate, polybutylen eterephthalate, and an ABS-copolymer and parameters characterizing mec hanical and electrical relaxation in the region of local molecular mob ility. A method is proposed for determining shock characteristics a pr iori on the basis of the temperature-frequency dependences of the elas tic modulus and mechanical loss modulus. The difference between the th eoretical and experimental values of fracture toughness, measured with in a broad range of temperatures, is no greater than 10-15%.
