ABSTRACT:
Two composite parts, such as sheet and a hollow gas turbine liner tile, are fastened together using a fastening system that includes a journal bearing that fits in a bore in the sheet and springs to support a bolt fastener that is tightened to hold the parts together. Resilient spacers are placed between the sheet and the liner. The springs may comprise a stack of rings, each ring being a tightly wound helical spring, giving the ring a hollow cross section and resilient qualities.
