Abstract
The present invention relates to a method of moulding a composite article using a mould. The mould includes first and second rigid mould parts between them defining a mould cavity. A reservoir of resin is connected to an inlet into the mould cavity. A suction pump is connected to a port on the opposite side of the mould cavity from the inlet. At least one of the mould parts has an arrangement of grooves on the surface facing the mould cavity to distribute resin across the mould cavity. The method includes laying up fibres in the mould cavity, injecting resin from the reservoir by running the suction pump to fill the mould cavity with resin, curing the resin article to form a moulded article and opening the mould and removing the article.
