Abstract

In this research, the ULTRAVIOLET RADIATION degradation effect, as an environmental impact on the mechanical properties of GLASS/POLYESTER COMPOSITES, is studied. Various samples are manufactured using polyester resin and exposed to ULTRAVIOLET RADIATION. In order to measure the residual strength of the material, the samples are exposed to ULTRAVIOLET RADIATION in the test chamber for a time equal to three, six and twelve months of the real life. Residual strength tests are performed on the radiated and virgin samples in order to compare the strength of these two types of specimens.After measuring the mechanical properties of the virgin and radiated samples, the mechanical properties of unidirectional and [0/90]s cross-ply Glass/Polyester laminated composites are analyzed using Micromechanical and Classical Lamination Plate theories. The results of the analysis are evaluated by performing experiments on the unidirectional and [0/90]s cross-ply Glass/ Polyester laminated composites. The results of experiments show a considerable loss in transverse STIFFNESS and shear STIFFNESS of the unidirectional and [0/90]8 cross-ply GLASS/POLYESTER COMPOSITES. The results of the experiments also show that adding ULTRAVIOLET ABSORBER ADDITIVES to the polyester resin prevents the mechanical degradation of the resin under ultraviolet redaction very well.
