<p>A method for manufacturing perforate, fibre-reinforced, composite material the method comprising the steps:- (a) providing a mould comprising a first part (1) having needles (3), a second part (2) cooperating with the first part to close the mould, and an intermediate part (7) located in use between the first and second parts; (b) laying up reinforcing fibres (9) in the first part of the mould, at least some of the fibres (9) being longer than required for the finished composite material, the fibres (9) if desired being impregnated or admixed with resin; (c) positioning the intermediate part (7) of the mould over the free ends of the needles (3), and folding the fibres of extra length (10) around and over the intermediate part (7); (d) assembling the rest of the mould; (e) if required, injecting resin into the mould; (f) curing the resin; and (g) dissassembling the mould, the composite material being removed from the needles (3) along with the intermediate part (7). t</p> |
