Comparative tests of the degradation mechanical properties 2 composite materials in high humidity and temperature

Abstract

The matrix absorbs moisture from the environment and plasticized, if the product is made of polymeric composite materials (PCM) is used in conditions of high humidity and temperature. The value of the glass transition temperature (Tg) and the limiting temperature of use of the product decreases. Use the following types of tests to determine the extent of degradation of mechanical properties of PCM: three-point bending, compression, and computation of the glass transition point.
