Summary

Temperature dependence of three-point bend strength of woven fabric boron nitride (BN)-coated Hi-Nicalon™ SiC fiber-reinforced SiC matrix composite has been studied. Amorphous BN was coated 0.4 m̈m on the surface of the fiber by CVD process and the composite was fabricated by repeated polymer infiltration-pyrolysis (PIP) process. The strength of the composite was measured from room temperature to 1693K. The room temperature strength of the composite was ∼350 MPa and it increased to 460 MPa at 1078K. The strength reduction occurred above 1078K and was attributed reduction in strength of the fiber strength. The temperature dependence of the strength was compared with carbon-coated standard Nicalon™ fiber-reinforced composite. It was found that the BN-coated Hi-Nicalon SiC fiber improved the strength up to elevated temperatures compared with the standard fiber-reinforced one.
