  • Process for preparing thermoplastic composites
    Patent number: 5236646
    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.

  • Apparatus for preparing thermoplastic composites
    Patent number: 5116216
    Abstract: An apparatus for processing thermo-composites is disclosed where individual lies of a prepreg, to be formed into a laminate, are processed under two, concentric vacuum chambers. Heat and consolidating pressure are applied under a first vacuum to the material and then a second vacuum is drawn under an outer, rigid shell.
