Abstract
The mechanical behavior of a given component formed from reinforcing ceramic fibers enclosed in a ceramic matrix is determined by subjecting a dummy component to mechanical testing. The dummy component is formed from low modulus organic resin fibers enclosed in a matrix of an organic resin having a correspondingly low modulus. The organic resin fibers have the same configuration and fiber architecture as those of the ceramic fibers.
