Automotive Composite Materials & Vehicle Stiffness Requirements

One of the performance challenges when using automotive composite materials, and in particular thermoplastic glass fiber composite plus over-molding resin, is meeting stiffness requirements for automotive applications at elevated temperatures (typically 90°C for automotive components such as cross-beams, lift gates, seating, etc.).

This presentation by Paul Kane, Advanced Development Leader for Automotive Thermoplastic Composites at DuPont Performance Materials reviews:

  • Properties of high glass-transition temperature (Tg) polythalamide (PPA) resins and their use as over-molding resins with stamped, continuous glass fiber polyamide inserts
  • Properties of high weight fraction (75%) continuous glass fiber thermoplastic laminate
  • Automotive composite materials performance at elevated temperatures
  • Mechanical property characterization for finite-element analysis (FEA)
  • Material humidity exposure properties
  • Processing guidelines

Kane also covers computer-aided engineering results showing stiffness (torsional and bending) when using automotive composite materials, and frequency analysis of an over-molded beam made from DuPont™ Vizilon® TPC.
