Stamp forming of carbon fibre/PA12 composites - a comparison of a reactive impregnation process and a commingled yarn system

Jan-Anders Edvin Maansson, Pierre-Etienne Bourban, Martyn Douglas Wakeman

Two forms of carbon fibre reinforced polyamide 12 (PA12) were compared during non-isothermal stamp forming. The first was a stretch broken commingled yarn woven into a fabric, studied at three initial preconsolidation levels. The second was produced by in ...
