Moulding of composite materials

摘要

Apparatus for moulding composite materials comprises a frame (8) holding the margins of a pair of elastomeric membranes (4, 5) substantially in a plane in facing relationship. The frame (8) is secured within a moulding chamber formed by upper and lower sections (1, 2) respectively to divide the moulding chamber into a mould side MS which contains a mould form (9) and an opposite side OS. A jack diagrammatically illustrated at (13) is provided for effecting relative movement between the frame and the mould form (9) in the direction generally perpendicular to the plane of the frame. A resin introduction port (19) is provided for introducing resin between the membranes (4, 5) at a central region Ducting (11) is provided for aspirating the inter-membrane space, and inlet ducts OSI and MSI and outlet ducts OS2 and MS2 are provided for respectively pressurising and aspirating the mould opposite side OS and the mould side MS of the moulding chamber. To be accompanied, when published, by FIG. 1 of the drawings.
