Abstract
The paper presents a numerical-experimental study of effective elastic characteristics and instantaneous strength of polymer reinforced composite material with fabric reinforcement structure. It is based on a series of experiments on stretching of samples, cut from a composite plate at different angles to reinforcement directions, and further analytical processing of the results. In order to clarify the received experimental data, a finite-element computational model of the composite sample in grips with fiber orientation at different angles to the applied load was constructed. Such a comprehensive approach allowed to obtain in-plane technical constants of composite material at room and elevated temperatures, as well as to determine parameters of its strength when loading in different directions. The above study expands the known data on physical and mechanical properties of polymer reinforced composite materials and enables evaluating the features of their anisotropy caused by a directed reinforcement structure of the composite.
