Lowden, R A; Stinton, D P

The effect of thin coatings deposited on NICALON fibers prior to densification with silicon carbide by chemical vapor infiltration was investigated. The thin films were applied to alter the strength of the fiber-matrix bond and to protect the fibers during processing. An indentation method developed to measure the strength of fiber-matrix bonding and frictional stresses was investigated and compared to a simple tensile test technique. The influence of the coatings on the bond strength and mechanical behavior of the composite products was examined. 36 refs., 10 figs., 2 tabs.
