Abstract
A structurally strong heat insulator is depicted in the backing plate and pressure plate regions of an aircraft multiple disc brake assembly. The insulator is constructed from a plurality of perforated metal sheets in order to withstand the large compressive forces experienced during a brake application. The sheets are compiled randomly into an insulating stack which thereby offsets the holes in adjacent sheets. The holes decrease the surface area and the offset increases the heat conduction path, both which reduce the amount of heat cnducted through the stack.
