Abstract:
A flange (1) made of composite material, a method of making the flange (1) and a mandrel (3) upon which the flange (1) is formed are provided. The flange (1) is a curved hollow member that has a substantially triangular cross-section. The method of making the flange (1) includes applying composite material to external surfaces of a curved mandrel (3). The mandrel (3) is curved and comprises a solid triangular cross-section. The method also includes curing the composite material to produce a flange (1) that is a curved hollow member that is substantially triangular in cross-section.
