ABSTRACT:
A fire wall constructed of a composite materials (10) includes a fire-protecting layer of intumescent material (16) integrated into the structure thereof. A plurality of layers of composite material (18) are laminated together to form the fire wall. An outer layer (14) is a shielding material such as fiber glass. Another layer (16) is an intumescent material in juxtapositional relationship between the outer shielding layer (14) and the composite layers (18). The shielding layer (14) and the intumescent layer (16) are co-cured with the composite layers (18) to make a fire wall having integrated fire-protection that is immediately usable without need of additional thermal protection materials.
