The Effect of Fiber Coating on the Temperature Dependence of the Elastic and Anelastic Properties of a Fiber-Reinforced Borosilicate Glass Matrix Composite

CODEN: JTEVAB

Abstract

Young's modulus and mechanical damping were determined for two borosilicate glass matrix composites reinforced with continuous ceramic fibers for the temperature range of 20–450°C using the piezoelectric ultrasonic composite oscillator technique (PUCOT). Scanning electron microscopy was also performed on the specimens. The effect of having a boron nitride fiber coating 0.2 μm thick on the properties of the composite as a function of temperature was determined. These and other measurements showed that the presence of the boron nitride coating improves the toughness of the composite without any penalty on the elastic modulus and damping characteristics.
