Use of electrical resistance and acoustic emission to monitor crack growth in advanced composite.
Silicon carbide composites are new hot section jet engine materials due to their high temperature strength and creep properties. However, much is still needed to be understood with regards to the nature of crack growth in these materials. Acoustic emission and electrical resistance are two techniques which have been used to monitor damage development during notch testing for these materials. The presentation will demonstrate the usefulness of these techniques when combined during tensile testing of single notch specimens for both in-plane and out-of-plane conditions.
