Abstract: A woven fibrous ion-exchange fabric is initially formed from fibers as in the form of threads, ropes or yarns which comprise a fluorinated polymer with sulfonyl-containing pendant side chains in the --SO.sub.2 X form wherein X is fluorine or chlorine. Conversion of the sulfonyl group in the polymer to ionic form causes longitudinal shrinkage of the fiber in the woven fabric and lateral fiber swelling thereby forming an essentially impermeable fabric to physical flow of liquid through spaces between the fibers. High strength is realized in the woven fabric without a need for reinforcing material.

Abstract: The efficient production of pervious low density carbon fiber reinforced composite articles is made possible through the use of the present invention. A fibrous open weave tape (as described) which is capable of undergoing conversion to a carbonaceous fibrous material is continuously passed in the direction of its length through a series of heating zones to form a fibrous carbon tape (preferably of graphitic carbon) wherein an open weave construction is maintained. At least one layer of the resulting fibrous open weave carbon tape may be impregnated with a thermosetting resinous material, and subsequently cured to form a pervious composite article.The composite articles exhibit a high specific modulus and strength, and are extremely lightweight. The lightweight composite articles may be utilized as structural elements, and are particularly suited for use as a facing sheet of an acoustic sandwich liner which serves as a noise suppression function in jet engines.
