Adherable reinforced poly(ethylene terephthalate) composite sheet and process.

摘要

Fiber-reinforced poly(ethylene terephthalate) sheet is laminated to a sheet of amorphous, adhesive copolyester at a temperature at which poly(ethylene terephthalate) is in a molten state. The resulting composite sheet is useful in making thermoformed articles in which one member is bonded to another member, for example, a face member and a backing member. The different members are arranged so that their copolyester layers face each other. Hollowthermoformed articles bonded with amorphous copolyester adhesive exhibit very good bond strength and minimum distortion.
