ABSTRACT:
A method of securing fiber reinforced glass matrix composite material to structural members is disclosed. Two materials to be secured together are provided with a hole or other opening for insert of the fastening means. A fastening means, preferably a rivet or bolt is provided by hot pressing glass matrix material in and around unidirectionally oriented continuous length silicon carbide fibers. Such material is coined and optionally provided with threading. After formation, the bolt or rivet is inserted into the opening provided to attach the materials together and the open end of the rivet or bolt closed either by nut means or by heat deforming. The resultant secured composite-structural member remains inseparable in use, for example, in an environment of extreme temperature fluctuation. The structural member can also be fiber reinforced glass composite material, metal, unreinforced ceramic or other high temperature composite. The rivet or bolt is formed by hot-press forming a fiber reinforced composite material, slicing longitudinal rectangular sections from the composite and coining the longitudinal sections. Heads are also coined on the longitudinal sections thus formed. For the bolt embodiment, threads are also machined on the coined part.
