Abstract (en)

[origin: WO9210362A1] Rapid production of honeycomb sandwich structures containing fiber-reinforced or non-reinforced thermoplastic honeycomb (1) adhered to skins or facing sheets (2) is accomplished by fusion bonding the skins or facing sheets (2) to the core (1) by means of thermoplastic film(s) (3) heated to the melt temperature (4) and applying sufficient pressure (5) fusion bond the skins or facing sheets to the core, followed, when necessary, by cooling the assembly (6) to prevent overheating of the core and/or skins or facing sheets.
