Thin perforated sheets of titanium (20) are interleaved between adjacently situated graphite/epoxy plies (12, 14) - in the area where metal fittings are to be installed (16, 22, 18). Epoxy flows through these perforations (24) so as to achieve a gripping mechanism between the titanium (20) sheet and the graphite/epoxy plies (12, 14). The result is efficient transfer of load in the titanium to the composite fiber materials without suffering the cost penalty of extensive graphite/epoxy buildups (without interleaved titanium sheets). Epoxy plugs within the titanium sheet perforations (24) bond to confronting surfaces of the graphite/epoxy plies and provide a fail safe gripping mechanism between the titanium sheet and adjacent graphite/epoxy plies in the unlikely event that the shear bond between the faces of the titanium sheet (20) and the graphite/epoxy plies (12, 14) becomes completely disbonded. |
