scope:

This International Standard specifies a method for the determination of in-plane shear strength of continuousfibre- reinforced ceramic composites at ambient temperature by the Iosipescu test. Methods for test piece fabrication, testing modes and rates (load rate or displacement rate), data collection, and reporting procedures are addressed. This International Standard applies primarily to advanced ceramic or glass-matrix composites with continuousfibre reinforcement having uni-directional (1-D), bi-directional (2-D) or 3-D fibre architecture. This test method does not address composites with discontinuous-fibre-reinforced, whisker-reinforced or particulate-reinforced ceramics.
