Abstract
To inhibit agglomeration of fibrous material during composite preparation and to increase transverse strength, particulates such as whiskers have been attached to the fibrous material. Whiskers can be economically grown on the fibrous material while it is transported lengthwise through a heated gaseous mixture under APCVD conditions and the presence of an agent for catalyzing the formation of whiskers. The fibrous material preferably is a roving or tow of a ceramic or carbon.
