A method of forming a scarf joint between first and second elongate composite components (1,2), each having a complimentary tapered end surface (4,5) is disclosed. At least one of the components is formed of a stack of fibre layers impregnated in resin, with the tapered end surface (4) being formed by each fibre layer extending longitudinally progressively further than the adjacent layer. The method comprises applying adhesive to at least one of the tapered end surfaces (4,5), attaching a moulding tool around the first and second elongate components with their tapered end surfaces being adjacent to one another, applying a positive pressure increase to urge the tapered surfaces (4,5) towards one another without locally reducing the pressure below the vapour pressure of the resin or adhesive throughout the curing process, and curing the resin and adhesive in the moulding tool with the pressure applied. 公开了在第和第二细长复合构件(1、2)之间形成斜面接头的方法，第和第二细长复合构件(1、2)各自具有互补的锥形端部表面(4、5。构件(1、2)中的至少个由浸渍在树脂中的纤维层的堆叠形成，其中锥形端部表面(4)通过各纤维层
