ANALYSIS AND PRODUCTION OF SUSPENSION PISTON PRODUCED WITH GLASS FIBER REINFORCED COMPOSITE THERMOPLASTIC POLYMER MATERIAL

Abstract

In the rapidly changing automotive industry, it is of great importance to lighten heavy vehicles, reduce emission values and increase energy efficiency. To achieve these goals, the use of reinforced polyamide materials is becoming increasingly common. These materials stand out for their high strength-to-weight ratio and are preferred in the automotive industry. Polyamides offer an environmentally friendly option as they are recyclable thermoplastic polymer materials. In particular, glass fiber reinforced polyamides provide both durable and light materials. In this study, the suspension piston, which is used to connect the lower axle of the air suspension spring used in heavy commercial vehicles, was produced from glass fiber reinforced thermoplastic composite material instead of traditional cold metal forming.
