Abstract
A composite structural component comprises an elongate member made of a polymer matrix composite material. The elongate member comprises a main portion extending along an axis A and an end portion with an inner surface extending from the main portion to an open end of the member. The composite structural component also comprises an end fitting forming a mechanical joint with the end portion, the end fitting comprising an internal portion positioned captive within the elongate member in contact with the inner surface of the end portion; an external portion positioned in contact with an outer surface of the end portion; and an adjustable fastener extending axially between the internal and external portions to clamp the end portion between the internal and external portions. The inner surface of the end portion in contact with the internal portion extends towards the axis A at an increasing angle to the axis A.
