ABSTRACT:
Thermoforming, utilized for making articles from sheets of thermoplastic ins, does not always yield articles having desired strength properties. It has been suggested that both thermoplastic and thermosetting layers be used to making the articles stronger. However it was virtually impossible to bond the layers together. A process is provided herein for obtaining that bond.
