Abstract
The present invention relates to a method of forming an extended elongate pressed composite assembly from a plurality of strands by subjecting the strands to heat and pressure. The improvement of the present invention comprises methods for compressing a particularly arranged composite mat of strands so as to compensate for internal stresses imparted to the pressed composite assembly during its subjection to pressure because of a converging compressing zone and card decking.
