Low the manner null which produces the density cutoff Characteristic thermal structural composite material and this kind of glass sandwich material

摘要

The material is composed of SiC/glass skins (layers) (2, 4), which are machined beforehand, and of an expanded-glass foam slab (loaf) (3), which form a sandwich structure. The material is obtained by installation on a rigid support, by applying to the assembly a uniformly distributed mechanical pressure and by heating in air at atmospheric pressure according to a specific temperature cycle of a temperature rise followed by a cooling. Application to load-bearing aircraft structures. IMAGE
