Abstract

A joint between two structural members of composite graphite fibre or other fibre-reinforced material, which may for example form part of the frame of an aircraft, is provided by interdigitated fibres of two bundles 18 and 19 each of which eventually forms one of the structural members 14 and 16. The bundles 18 and 19 are positioned so that they intersect one another at an angle and the graphite fibres are interdigitated at the point of intersection. The fibres are bonded together with a curable resin so as to form a rigid joint. A joint of this kind permits even distribution of structural loads irrespective of the direction of the load force. The joint may be further reinforced by the addition of a third bundle of fibres 32 which extends at an angle to both bundles 18 and 19 and which are interwoven with the fibres of both members 14 and 16 at the intersection. <IMAGE>
