Abstract

A method of manufacturing an elongated composite structure having two separate longitudinal composite structure sections, where said method comprises the following steps: providing a rigid mould part (13) having a first forming surface (14) with a contour defining an outer surface of the elongated composite structure, arranging a first fibre lay-up (15) in a first longitudinal section (16) of the first mould part (13), arranging a first flexible foil (18) over a first crosswise edge area (17) of the first fibre lay-up (15), arranging a second fibre lay-up (20) in a second longitudinal section (21) of the mould part (13) so as to overlap the crosswise edge area (17) of the first lay-up (15) and thereby the first flexible foil (18) in an overlap area (22) forming an interface between the fibre lay-ups (15,20), arranging a second flexible foil (23) over the second fiber lay-up (20), providing polymer to the fibre lay-ups (15,20) and allowing the polymer to cure.
