A method for manufacturing a hollow load-bearing beam structure of fiber-reinforced composite material. The method includes preparing a first lay-up of a first plurality of layers, and a second lay-up of a second plurality of layers. The first and second lay-ups are positioned on different sides of a mandrel and formed to a beam structure by bending the lay-ups against the mandrel, such that the side edges of the respective layers of the first and second lay-ups are arranged as offset butt joints in the circumferential direction of the formed beam structure.

A tool assembly including a male tool including an inner shape tool including a bag having a connection connectable to a depressurization source for providing a vacuum in the bag such that beads therein form a body of firm cohesion providing the inner shape tool rigid. The male tool further includes a flexible, hollow curing support arranged around the rigid inner shape tool, the inner shape tool is arranged to be removable from the flexible, hollow curing support by rupturing the vacuum.
