Abstract
A forward pressure bulkhead for aircraft includes an energy dissipating material layer, a metallic or nonmetallic inboard skin with a porous filler material positioned within said layers. The energy and load distribution layer redistributes and disperses energy of impacts and penetrations. The porous filler material is a material having ligaments that collapse resulting in a densification of the porous filler material in response to impact loading or a compression force sufficient to cause failure of the combined assembly.
