Abstract
A method of shaping elongated composite structures of a resin matrix reinforced with randomly broken fibers oriented in transverse and non-transverse directions with respect to the longitudinal axis of the structure is implemented by a computer aided apparatus for forming the structure. The apparatus is provided with a heated fixed forming tool, a means for stretching the structure from each end and means associated with the forming tool for separately holding each formed component length of the structure in place against the forming tool. The formed structure is characterized by the particular orientation of the fibers in the transverse and non-transverse direction after the structure is formed.
