Abstract

The composite structure has a honeycomb core with stronger surface layers. A hollow spacer which is initially of uniform diameter is inserted into a matching hole in the sandwich structure so that the spigot at its lower end fits the hole in the lower surface and its upper end is flush with the undersurface to be fastened and forced into the spacer, forcing the spacer into matching shape and causing the upper end wall to slide under the surface. A head is then formed on the lower end of the rivet.
