Method of Forming Laminar Composite Charge

摘要

A method of forming a charge. A first part of the charge is clamped with a free part of the charge protruding from the clamp to a free edge of the charge. The free part of the charge comprises an inner layer, an outer layer and a plurality of internal layers. The outer layer is contacted with a forming roller and the inner layer is contacted with a guide roller. The free part of the charge is bent over a convex corner of a die with the forming roller to form a first bend with the outer layer on an outside of the first bend. The free part of the charge is also bent away from a mould surface of the die with the guiding roller to form a second bend with the inner layer on an outside of the second bend. The rollers are simultaneously moved across the mould surface so that they progressively draw the charge across the mould surface, the forming roller presses the inner layer of the charge against the mould surface, and the second bend moves towards the free edge of the charge.

1. A method of forming a charge, the charge comprising a plurality of layers of fibre-reinforced composite material, the method comprising:
clamping a first part of the charge with a clamp, a free part of the charge protruding from the clamp to a free edge; contacting the free part of the charge with a forming roller; and advancing the forming roller across a die so that it bends the free part of the charge over a convex corner of the die, wherein as the forming roller advances across the die it rotates about an axis of rotation which also advances across the die.
