In this investigation, the mechanical behavior of poly(methylmethacrylate) due to aging in Xenon test chamber, using a xenon-arch lamp as a light radiation to simulate natural sun light has been studied. This work studies the mechanical properties (elongation at break. Young's modulus, tensile strength and toughness) of PMMA samples exposed to different aging conditions (until 1560 h xenotest that correspond to 750 days exposure at natural light). The evolution of different mechanical properties characterizes the PMMA's process of degradation.
