Mechanical Resistance of PC and PMMA Safety Components in Transportation

Polycarbonate (PC) and polymethyl methacrylate (PMMA) are widely used thermoplastic polymers in transportation applications due to their exceptional optical clarity, impact resistance, and durability. These materials are integral to safety-critical components such as vehicle light covers, protective shields, and sensors. In this study, PC and PMMA specimens of varying thicknesses were tested using drop-weight impact tests to evaluate their mechanical properties, specifically puncture resistance. The primary objective was to compare the impact resistance and overall performance of these materials under dynamic loading conditions. Statistical analysis revealed that PC outperformed PMMA in mechanical performance, though modifications to PMMA can enhance its impact resistance. This research provides practical insights for optimizing material selection in transportation, ensuring a balance between durability and cost-efficiency.
