In each of these tests, the reinforcement must be of a monolithic form. Consequently, they rarely contain the exact sur- face chemistry, microstructure, or residual stress profile of the true fiber-matrix pair. Therefore, the discussion here is limited to those geometries in which the fiber and matrix can be made identically to those in an actual composite rather than to those geometries that allow materials only similar to the mate- rials used in the composites.
