Abstract:
Composites are well-known to provide good weight reduction and more creative design freedom in automotive closure applications versus traditional ferrous or non-ferrous stamped metal assemblies.Challenges to widespread adoption of composite structures include: Recyclability of the end unit without disassemblyJoining together panelsKeeping up with high production volumesLimited structural strength without significant metal reinforcementTotal delivered costLatest generation composite liftgates can achieve high levels of component integration and maximum styling freedom by utilizing fully thermoplastic recyclable injected molded panels. Proper material characterization and CAE optimization can reduce the level of internal metal reinforcements, thereby realizing further weight reduction opportunity.
