摘要： There is disclosed a method of manufacturing edge-reinforced lightweight composite components (10), the method comprising: disposing at least one layer (or mat) of fibres on a first mould surface (31); disposing a filler (13) on said layer or layers (16) of fibres, the filler (13) being adapted to provide localized reinforcement at the edge of the composite component (10); forming a loop (18) around the filler (13) with at least one of the layer or layers (16) of fibres; disposing a second mould surface (32) relative to the first mould surface (31), such that a mould cavity is formed between said first and second mould surfaces; and transferring a mixture (41) through a mould (30) into the mould cavity (33), the mixture (41) comprising a resin and a curing agent, thereby allowing said mixture (41) to impregnate the layer or layers of fibres, before the resin cures. Reinforced lightweight composite components (10) having high stiffness at the edge can thus be advantageously manufactured, using a standard Resin Transfer Moulding technigue, while preventing sharp and/or unsightly edges.
