Hygrothermal Effect

An analytical model based on the displacement function of the opening of crack applied by Lundmark and Varna [26] in the internal layers to study the evolution of the decrease of stiffness in a laminate is investigated. The results of axial rigidity versus the crack density are presented for three composite materials. The influences of the temperature and moisture on the mechanical properties of composite material are highlighted. The micromechanical model of the laminates used in present study describes the degradation of the mechanical properties of composite material by the variation in the temperature and moisture. The hygrothermal effect is observed to be harmful for composite materials.

Properties Of Composites

This letter reports a new and general micromechanical model for estimating the mechanical properties of composites made of two component materials, i.e. fibers and bodys. The backbone of the model is a bridging matrix of coefficients connecting the macro-stresses of a body with those of a fiber in a representative volume. A semi-empirical approach has been proposed to identify the matrix with which all the mechanical properties of the composite can be easily obtained.

A study review of aging polymer composite materials (PCM) under different heat-moisture conditions or water exposure with the sequential or parallel influence of static or cyclic loads in laboratory conditions is presented. The influence of tension and bending loads is compared. Conditions of the different load influence on parameters of carbon-reinforced plastics and glass-reinforced plastics are discussed. Equipment and units for climatic tests of PCM under loading are described. Simulation examples of indices of mechanical properties of PCM under the influence of environment and loads are shown.
