Abstract

The article is devoted to the study of the influence of thermocyclic effects and operating temperature on the properties of polymer composite materials based on the fiberglass and epoxy binder. It is established that the «heating–cooling» cycles for fiberglass with different polymer matrix content and reinforcement options cause some decreases in strength and elastic dynamic characteristics, but this does not adversely affect the operation of protective screens or engine nacelles for gas turbine engines made of fiberglass.
