Abstract : Preforms were woven in three directions, 3-D, with center-to-center spacings of 0.030, 0.040 and 0.125 inch using Thornel 50 and Thornel 400 yarns. The billets were partially densified with selected impregnants, pyrolyzed, and delivered at a 1.0 g/cc average density. The billets are being densified using chemical vapor deposition, and will be tested. (Modified author abstract)
