Mechanical resistance of safety elements in transportation

Abstract

Polycarbonate is a thermoplastic polymer used in many sectors including security and transportation. Polycarbonate plastic parts can be used in automotive applications because of their low strain, durability, performance, and slow deterioration. This engineering polymer is easily moldable, processable, and thermoformable. This article tests the polycarbonate shield, grit from the polycarbonate shield, and injection molded polycarbonate specimens on a drop-weight impact test. This study is focused on the comparison of the mechanical properties (especially on the impact resistance) between injection molded polycarbonate, and polycarbonate safety shield. Statistical evaluation of the results shows that the injection molded polycarbonate does not reach the mechanical properties of the protect shield.
