Abstract
A ceramic fastener assembly for high temperatures. One embodiment is a fastener assembly that includes a ceramic fastener configured to engage a hole of a structure. The ceramic fastener includes a head and a non-threaded shank including one or more indentations around its perimeter. The fastener assembly also includes a sleeve configured to slide over the non-threaded shank of the ceramic fastener. The sleeve includes a hollow cylindrical body, an exterior surface with threads, and an interior surface with one or more protrusions configured to mate with the one or more indentations of the non-threaded shank. The fastener assembly further includes a nut configured to engage the threads of the sleeve to tighten the one or more protrusions with the one or more indentations of the non-threaded shank. The fastener assembly also includes a thermal spacer configured to thermally isolate the nut and the sleeve from the structure.
