<p>A method of press moulding a moulding material to form a moulded part of fibre-reinforced resin matrix composite material, the method comprising the steps of: i. providing a mould tool having a lower mould part and an upper mould part, the upper mould part having a first moulding surface for moulding a first moulded surface of the moulded part and the lower mould part having a second moulding surface for moulding a second moulded surface of the moulded part; ii. providing a multilaminar panel of moulding material comprising at least one layer of fibres and at least one layer of resin, the multilaminar panel having first and second opposite major surfaces, a surface resin layer of the multilaminar panel being at or adjacent to the first major surface; iii. locating the moulding material in the mould tool; iv. closing the mould tool to define a substantially closed mould cavity containing the moulding material, the closing step including the sub-steps of: a. partially closing the mould tool to define a closed intermediate cavity containing the moulding material, the closed intermediate cavity being larger than the moulded part and the first moulding surface of the upper mould part being spaced from the first major surface, the upper mould part being at an elevated temperature as compared to the temperature of the moulding material; and b. at least partially evacuating air from the closed intermediate cavity while the first moulding surface of the upper mould part is spaced from the first major surface; v. applying pressure to the moulding material in the mould cavity to configure the moulding material in a fully moulded shape; and vi. substantially fully curing the resin to form a moulded part from the moulding material.</p> |
