ABSTRACT:
A method of shaping a thermoformable composite material including a polymeric matrix reinforced with continuous filaments which involves locating the material in overlapping relationship with at least one diaphragm of a thermoformable shaping polymer, heating the assembly to a suitable thermoforming temperature and shaping the assembly against a shaping tool surface in a shaping step of less than two minutes.
