摘要：A method of forming a laminar composite structure. A stack of compositelayers is assembled on a layup tool, each composite layer comprising a fibre-reinforcedmatrix material. The composite layers include an inner composite layer and an outercomposite layer. During assembly of the stack, a series of spacers are placed in a
selected part of the stack, each spacer comprising a spacer matrix material. Each spacer issandwiched between a respective adjacent pair of the composite layers. The selectedpart of the stack forms a bulge, and the outer composite layer has a greater path lengthat the bulge than the inner composite layer. After assembly of the stack, a bend isformed in the stack with the outer composite layer towards an outside of the bend andthe inner composite layer towards an inside of the bend, the bend in the stack coincidingwith the bulge. During or after formation of the bend in the stack, excess matrix material
in liquid form flows out of the bulge.
