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 gmcc. Models were machined for each of nine billets and supplied to AMMRC for testing at AFMLs 50 mw facility. Author-PL
