Abstract
Disclosed are a high-purity alumina continuous filament woven fabric comprising a high-purity alumina continuous filament having an alumina content of at least 95% by weight and a filament diameter of 5 to 20 .mu.m, a hybrid woven fabric comprising this high-purity alumina continuous filament and a high-strength continuous filament having a tensile stength of at least 200 kg/mm.sup.2, processes for the preparation of these woven fabrics, a high-purity alumina continuous filament valuable for the production of these woven fabrics, and a process for the preparation of this high-purity alumina continuous filament. These woven fabrics are very useful as a reinforcing fibrous substrate of a fiber-reinforced composite material or as a heat-insulating material.
