The effect of temperature on the tensile, shear and compressive properties of E-glass/epoxy laminated composites

Composite structures are under different loading conditions such as thermo-mechanical loadings. The present research aims to investigate the temperature-dependent mechanical behavior of glass-epoxy laminated composites. Three types of loading conditions including tensile, shear, and compressive loading were considered under temperature in the ranges of ۲۵-۱۵۰ °C. A wide range of experiments was conducted. The load is measured by a ۳۰۰ kN load cell of class ۰.۵ and strain was measured using the digital image correlation method of class ۰.۵. Two types of laminated glass/epoxy composite including woven glass cloth/epoxy resin and glass mat/epoxy resin were used. Different temperature-dependent mechanical properties of a laminated composite including elastic modulus, Poisson’s ratio, tensile strength, and elongation at fracture were measured. Results show that temperature has a significant effect on the mechanical properties of laminated glass/epoxy composites.
