Abstract
This invention relates to a shaped fibrous material for use in the manufacture of fiber-reinforced metals comprising a uniform mixture of ceramic fibers and aluminum borate whiskers. The invention also relates to a method for producing the shaped fibrous material comprising the steps of dispersing ceramic fibers and aluminum borate whiskers in a suitable solvent containing a binder to form a slurry, transferring the slurry into a suction molding, aspirating and dehydrating the slurry to form a shaped dehydrated fibrous material, and drying and firing the shaped dehydrated fibrous material to obtain the shaped fibrous material. The shaped fibrous material can be cast efficiently into a fiber-reinforced metal with a high yield. The thus produced fiber-reinforced metal has a high wear resistance combined with a very mild nature of attacking the mating member.
