In order to advance from material properties determination to performance evaluation of engineering components, a transition from coupon testing to actual component testing is required. A prerequisite to this transition is the development of reliable mechanical test methods. A simple gripping method for testing ceramic matrix composite tubular specimens is developed. Tensile and torsional tests were performed on woven Sumitomo fiber reinforced alumino silicate tubular specimens, in which gage section failures were controlled by using this method. This method can be applied to biaxial testing of CMC straight-sided tubular specimens at elevated temperature. Details and limitations of the method will be discussed, in the context of the material system tested. Experience with the method is described, and continuing directions for method development are suggested.
