Abstract

Fibrous monolith processing techniques to fabricate multifunctional structures capable of performing more than one discrete function such as structures capable of bearing structural loads and mechanical stresses in service and also capable of performing at least one additional non-structural function.

Claims

1. A fibrous monolithic structure comprised of

a core material and a shell material

wherein one of the materials comprises an electrically conductive material and the other material is an electrically insulating material.
