Polymers have become one of the most widely used types of materials over the past few decades. One application of polymers is in polycarbonate roofing. Polycarbonate is used for roofing applications due to its supportive properties and structure, such as transparency, high impact resistance, and a sufficient temperature range for extreme environmental applications. These extreme environments pose a unique challenge for polycarbonate, as elements like rain, storms, wind, dust, and sun exposure can damage it. Therefore, a study was conducted on the wear performance and degradation of polycarbonate using water jet erosion and heat aging degradation methods. Water jet erosion here allows for the simulation of polycarbonate's performance in facing erosive wear as in its practical applications, while heat aging serves as a test to understand the decline in polycarbonate's performance when undergoing degradation. The study found that polycarbonates do not experience significant wear impacts from particle velocity, particle reduction rate, or material degradation. Significant wear impact on polycarbonate only occurs at the particle attack angle.
