In-plane shear tensile characteristics of polyester composites: Effects of sunlight exposition

摘要

This work focusses on the analysis of in-plane shear tensile test carried out on samples aged by UV-Visible light. The tendency of in-plane shear properties with exposure time fits to a decreasing exponential curve. Different thermosetting polyester resins, curing temperatures profiles, and fibreglass fabrics are employed for this study. The type of resin and curing temperature influence on elastic modulus and shear strength of composite. The ageing degree varies between 14% and 25%, depending on shear property and the composition.
