ABSTRACT:
A process for continuously and progressively forming components from fiber-containing composite material workpieces having a deformable matrix introduces transverse bends into a workpiece that moves through the apparatus in a longitudinal or travel direction. Transverse bending of the composite material is accomplished in a kinematically admissible manner to avoid misalignment or failure of the composite material. A net bending deformation is introduced at a free transverse edge as the composite workpiece moves in a longitudinal direction, by pairs of compound roller elements between which the workpiece passes as it moves through the apparatus. The net deformation introduced at the free transverse edge is moved and distributed through the composite material workpiece during successive passes through the forming machinery, to form the final shaped component.
