Abstract
A method for thermostamping thermoplastic composites involves the steps of (a) convection heating of the composite to the glass transition temperature of the thermoplastic; (b) radio frequency heating of the composite from the glass transition temperature of the thermoplastic to the desired stamping temperature; and (c) stamping of the composite into the desired shaped article. The method provides for improved temperature uniformity throughout the composite prior to stamping thereof resulting in more uniform parts.
