Mechanical behavior of PMMA due to artificial aging by means of a xenon-test chamber

In this investigation, the mechanical behavior of poly(methylmethacrylate) due tu aging in Xenon test chamber, using a xenon-arch lamp as a light radi ation to simulate natural sun light ha, been studied. This work studied, th e mechanical properties (elongation at break, Young's modulus, tensile stre ngth 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 PMMAs process of degradation.
