Abstract
The present invention relates to a fiber-based, fire-resistant fabric comprising a mixture of: PA1 (a) about 50-90% by weight of textured fire-resistant fibers; PA1 (b) about 10-50% by weight of technical fibers of stiffness greater than that of textured glass, provided that if fibers (a) are fibers of textured glass, fibers (b) are not carbon fibers. The preferred textured fibers are glass fibers. Fibers (b) can be fibers of carbon, aramide or silicon carbide. The fabrics are useful for the manufacture of fire-resistant composite articles impregnated with phenolic resin.
