ABSTRACT:
A thermoplastic laminated billet is made by dielectrically heating a stack of thermoplastic billets or layers within a mold press, wherein the sequence of dielectrically heatable and non-heatable individual layers is such that no more than a tie layer separates a heatable and non-heatable layer so that only that portion of the non-heatable layer nearest the heatable layer or layers melts. The laminated billet is formed within the mold press that has electrodes formed therein, the electrodes capable of impressing on the dielectrically heatable layers used to form the laminated billet sufficient energy to melt the heatable layers and at least a portion of the adjacent non-heatable layers.
