5 Sheet forming in polymer matrix composites Chapter uri icon

abstract

  • Abstract: Key objectives in sheet forming are reduced cost per component, increased production and continuous stepwise processing. Thermoplastic sheet forming turns a flat composite laminate into a structural shape when dies or diaphragms press the laminate while the thermoplastic is liquid. The matrix flows and the fibres move as the laminate adopts its new shape. Designers must accept larger variances in fibre placement than present in other processes. Stretch-broken carbon fibres have renewed interest in sheet forming. Advanced thermoplastics made via in situ ring-opening polymerization might reduce processing time because low-viscosity precursors form high molecular weight chains during thermal processing.
