| Description: |
International audience ; In the present work, the interfacial properties between two carbon fibers, with different surfaceroughness, and PEEK were studied using multifragmentation tests with model single-fiber composites.Acoustic emission instrumentation was used to detect and locate fiber breaks in the specimen. Thismethod was validated by microscopy observations. Moreover, acoustic emission data showed that thetwo studied fibers have a different dependency on strain for fiber fragmentation. In situ, X-raytomography fragmentation tests provided information on fiber fragmentation and matrix behavior in thezone near a fiber break. Interfacial shear strength for both systems studied was estimated, showing alimited effect of the fiber's roughness. Fiber fragment lengths measured by microscopy, acousticemission, and tomography techniques demonstrated good agreement |
