Abstract

Moulding and curing resin impregnated fibres in a female mould fitted with a clamped male cover lined with a flexible elastic bag which can be filled or pressurised with a supply of temp. controlled gases or liquids to generate the required moulding pressures. Pref. the bag can be initially pressurised by air to consolidate the laid matting, then progressively filled with liquid to displace air from the moulding cavity prior to applying the moulding pressure. A smooth flexible microporous skin may be used to interface between the pressurised bag and the moulding surface to ensure that no air bubbles are trapped against the moulding surface. For moulding reinforced thermosetting resins at pressures of 0.5 - 5 kg/cm2 or more, opt. with gel coat resins painted on to the cavity walls. Does not involve a large hydraulic press, provides more progressive degassing and better heat trasnfer than simple pneumatic bag vacuum or pressure forming presses. Liner collapse facilitates release of the moulding. Heat distribution is uniform and reproducible, can be rapid using bag with a cavity only 5 mm. wide.
