Abstract : 3-D preforms, supplied by AMMRC, with center-to-center spacings of 0.125, 0.040, and 0.030 in. using Thornel 50 and rigidized with phenolic resin furfuryl alcohol resin and pitch were den-sified by the differential pressure chemical vapor deposition process. The highest density achieved was 1.56 gm/cc. Models were machined for each of nine billets and supplied to AMMRC for testing at AFML's 50 mw facility. (Author-PL)
