Abstract

A porous composite product comprised of a network of fibers is produced by forming an unsintered preformed network of fibers and a gasifiable structure forming agent, followed by gasification of the structure forming agent prior to sintering of the fibers at appropriate junction points. The preferred structure forming agent is a cellulosic material.
