ABSTRACT:
This invention relates to a process for preparing thermoplastic composites .e. laminates from a plurality of individual plies of thermoplastic resin prepregs. The prepregs are formed into composites under two substantially concentric vacuum chambers. High temperatures and low consolidating pressures are applied against the prepregs in an inner vacuum chamber while a lower vacuum is drawn from the rigid outer chamber to remove the volatiles and consolidate the prepregs.
