Process for twin sheet forming high heat distortion temperature thermoplastic and articles made therefrom.

摘要

A method for twin sheet forming layers high heat distortion temperature thermoplastic materials. The process employs a low heat distortion temperature thermoplastic material layer disposed between the layers of high heat distortion temperature material layer to permit adhesion therebetween at moderate temperatures to reduce thermal degradation. The structures made therefrom are useful as aircraft ducting.
