Fiber pull-out method

The direct methods of characterizing the fiber-matrix adhesion and the interphase, have relied on the use of single-fiber-matrix test methods for measuring adhesion and failure modes. The first technique proposed was the fiber pull-out method... [Pg.607]

The fiber-bundle pull-out method [19] is similar to the single-fiber pull-out method except that instead of using a single fiber, a bundle of fibers is used. A coupon is fabricated in which a bundle of fibers or a lamina of unidirectional fibers is cast in a block of matrix. Transverse notches are cut into the coupon near the end of the fiber bundle. The coupon is loaded in tension with the load applied parallel to the fiber axes. The load versus displacement curve can be monitored and the debonding point detected. In a similar manner to the way data are reduced for the single-fiber pull-out test, the interfacial shear strength between the bundle of fibers and matrix can be calculated. [Pg.611]
