Effect of UV-C long-time irradiation on mechanical properties of PMMA

This study aims to examine the effects of long-term exposure to high levels of UV-C radiation on the mechanical strengths of PMMA. PMMA is known to degrade when exposed to UV radiation, which can lead to a fragile fracture layer on its surface. The study was conducted by exposing standard commercially available PMMA plates to UV-C radiation using a purpose-designed irradiation stand. The samples were tested using a tensile test machine to measure mechanical properties. The results of the study provide important information on how PMMA reacts to long-term exposure to UV-C radiation and can help manufacturers design and produce products using PMMA construction materials that can withstand exposure to UV-C radiation.
