A stack of composite layers 1-9 is assembled on a layup tool 10, each composite layer comprising a fibre-reinforced matrix material. The composite layers include an inner composite layer 1 and an outer composite layer 9. During assembly of the stack, a series of spacers 20, 22, 23 are placed in a selected part of the stack, each spacer comprising a spacer matrix material. Each spacer is sandwiched between a respective adjacent pair of the composite layers. The selected part of the stack forms a bulge, and the outer composite layer has a greater path length at the bulge than the inner composite layer. After assembly of the stack, a bend is formed in the stack with the outer composite layer towards an outside of the bend and the inner composite layer towards an inside of the bend, the bend in the stack coinciding with the bulge. During or after formation of the bend in the stack, excess matrix material in liquid form flows out of the bulge. |
