A fixture is described for bonding a plurality of porous friction material segments (76) to the frusto-conical surface (62) of a support member (40). The fixture includes a base member (94), ring members (86) which have frusto-conical surfaces complementary to the surfaces on the support members (40), between which segments of friction material (76) are glued and means (96,98) for clamping the assemblies to the base with a predetermined force while the whole assembly is heated and the adhesive is cured. Methods of bonding openly porous pyrolitic carbon composite friction material to blocker rings (40) of blocker clutches are described as well as gearboxes including such rings. |
