摘要：A polymer is formed into the shape of a one-piece composite part and thensolidified by curing, setting, hardening or otherwise solidifying the polymer to form ashaped polymer form having a shape that does not draw. Composite material is laid upon the form and solidified to form the composite part. The rigidity required of the formto lay up the composite part can be provided by operating in the polymer form's glassystate, forming the shaped polymer form with a hollow core and placing a rigid insertdesigned to draw inside the hollow core with the polymer form in its elastomeric state orthrough a combination of both. In its elastomeric state the form becomes pliable(without relaxing to a different memorized shape) and can be drawn oυt of the one-piececomposite part. Because the shape of the form does not draw, the form deforms as it isdrawn. If used, the rigid insert is drawn out prior to removing the shaped polymer form.Upon removal, the polymer form in its elastomeric state returns to its original shape. Theform may be used once and thrown away or reused to form multiple composite parts ofthe same shape.
