ABSTRACT:
Rapid production of thermoplastic sandwich structures containing fiber-reinforced or non-reinforced thermoplastic core, such as honeycomb, materials adhered to skins or facing sheets is accomplished by fusion bonding the skins or facing sheets to the core by means of thermoplastic film(s) heated to the melt temperature and applying sufficient pressure to fusion bond the skins or facing sheets to the core, followed, when necessary, by cooling the assembly to prevent overheating of the core and/or skins or facing sheets.
