ABSTRACT:
A continuous forming method is provided here whereby long composite structural shapes such as "Z", "HAT", "L", etc. can be formed economically with relatively small equipment. First, a lay-up is made from unidirectional tape or woven cloth, then the material is heated to accommodate softening of resin, then pulled through a set of rollers, then through a matched metal die and a rapidly reciprocating punch that facilitates to form the final shape. As the material is pulled through the area of match metal die and punch, it is cooled down by the heat sink of the die and punch, or any other means, so when the part exits the die and punch area, it is sufficiently cooled down to retain the desired shape. The rapidly reciprocating punch permits the part to be pulled continuously, thereby enabling it to produce a long part very economically.
