초록 ▼

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.

대표청구항 ▼

A process for the continuous preparation of honeycomb sandwich materials by adhering one or more skins to a thermoplastic honeycomb core without causing collapse or deformation of the core comprising: (a) supplying the thermoplastic honeycomb core to a heating zone; (b) supplying a facing sheet comprising a layer of thermoplastic material at least at the surface of said facing sheet facing to said honeycomb core; (c) applying heat in said heating zone via a non-contacting heat source to the exposed surface of said layer of the thermoplastic material of said facing sheet and to the exposed surface of said thermoplastic honeycomb core to raise the temperature of said exposed surfaces to the fusion temperature of the thermoplastic materials; and (d) essentially simultaneously and continuously joining the heated thermoplastic honeycomb core, the heated layer of thermoplastic material and the facing sheet and applying pressure to the resulting sandwich structure sufficient to cause the facing sheet to be fusion bonded to the thermoplastic honeycomb core via said thermoplastic layer but insufficient to cause deformation or collapse of the honeycomb core.
