Abstract

A method of manufacturing a composite part comprises providing a molding tool (10) comprising a tool base (14) and a tool lid (16), both configured to form a cavity (18) between the tool base (14) and the tool lid (16) tool when the molding tool (10) is closed. A fibre preform (22) is placed in the tool (10) which is tightly closed so that the fibre preform (22) is within the cavity (18). A predefined clamping pressure (PC) presses the tool lid (16) and the tool base (14) against each other, and a resin (28) is injected into the cavity (18) at an injection pressure (PI) to infiltrate the fibre preform (22) with the resin (28). The size of the cavity (18) is passively increased by allowing an opening movement (OM) of the tool lid (16) relative to the tool base (14) and I or an elastic deformation (32) of the tool, when the inner tool pressure (PI) is greater than the predefined clamping pressure (PC), while keeping the cavity (18) tightly closed.
