There is provided a composite having improved structural integrity and suitable for use in abrasive, high temperature environments. The composite comprises randomly laid and oriented heat resistant fibers interlocked together into the form of a shape sustaining paper having two lateral surfaces. The paper has a thickness of from about 0.01 to 0.50 inch. An abrasion-resistant, high temperature resistant scrim is disposed upon at least one of the lateral surfaces of the paper, and a network of abrasion-resistant, high temperature-resistant threads is stitched through the scrim and the paper such that the scrim is mechanically locked to the paper by said threads. The network of threads and the scrim substantially retain the structural integrity of the said paper in use in the abrasive, high temperature environments.
