  • Ceramic matrix composite capped bolt attachment
    Patent number: 7967562
    Abstract: A fastener for a turbine engine includes a bolt and a ceramic matrix composite (CMC) cap mechanically secured to the bolt. CMC components are attached to an exhaust nozzle case with the fasteners. The fastener includes a bolt made of metal and having a head. A CMC cap is located on the head of the bolt and secured to the bolt by a mechanical device. The mechanical device allows the CMC cap to have a different thermal expansion than the bolt. The CMC cap also acts as a thermal shield for the bolt, aiding in the reduction of a heat signature of the turbine engine.
