ABSTRACT:
A configuration and method for reducing the flammability of bodies of organic materials that thermally decompose to give flammable gases is disclosed to comprise covering the body with a flexible matrix that catalytically cracks the flammable gases to less flammable species. Optionally the matrix is covered with a gas impermeable outer layer. In a preferred embodiment, the invention takes the form of an aircraft seat in which the body is a poly(urethane) seat cushion, the matrix is an aramid fabric or felt and the outer layer is an aluminum film.
