摘要： A rigid, non-metallic laminate suitable as a fire barrier, made by impregnating a layer of non-metallic fibers other than glass fibers with a resin, coating glass fibers with a refractory aluminum silicate to form a sheath, superimposing a layer of the thus alumina silicate coated glass fibers on the resin impregnated layer of non-metallic fibers and then subjecting the resulting laminate simultaneously to heat and pressure to squeeze resin from the non-metallic fibers into the interstices of the alumina silicate coated glass fibers and to cure the resin binder. A rigid multi-layer laminate in a common resin binder useful as a fire resistant panel or duct for a gas turbine engine results.
