A fibre reinforced composite shaft (Co) bearing a metallic flanged end coupling (Me) attached to the outside diameter through a concentric cylindrical torsional joint, The composite tube is press fitted into a flanged metallic end coupling (Me) comprising a multiplicity of teeth (Te) running parallel to the tube axis which cut longitudinal channels into the outside diameter of the composite tube wall during the press fit process. Pairs of inverted troughs (Tr) adjacent to and running parallel to the cutting teeth in the serrated region allow space for the redistribution of the composite material and debris (Deb) formed during the press fitting process. This combined action forms a mechanical interface (In) capable of supporting torsional and axial stresses. A structural adhesive (Ad) may be applied to the joint region to form a secondary joint. In this case the composite formed between the cutting debris and the adhesive fills the trough channels. The secondary load path so formed further enhances the joint mechanical and environmental stability. |
