Model of thermomechanical behavior of structures reinforced by fibrous plastic

Dependence of tensile strength of CFR with fiber reinforcement circuit 45°/0/-45° on maximum heating temperature is considered. This dependence is constructed according to the results of field experiment. The relation between excess of glass transition temperature and ultimate strength of the sample was established. It was concluded that it is possibile to make equilibrium equations for numerical modeling of structures made of polymer composite materials under joint force and multiple temperature effects, at temperatures slightly higher than glass transition temperature.
