A simple analysis is proposed to include the surface roughness of the fiber in the push-out model. Specifically, the roughness effect is characterized by the difference between the fiber push-out stress and the fiber reseating stress, which is obtained from fiber push-back tests. A method is developed to analyze the loading stress vs fiber-end displacement relation (i.e. the push-out curve) during the push-out process to evaluate the interfacial properties. The push-out curve for composites with weak fiber bonding can readily be analyzed by the existing push-out model incorporated with the roughness effect. However, premature catastrophic debonding at the interface is required to interpret the push-out curves for composites with strong fiber bonding. ? 1995.journal article10.1016/0961-9526(95)99801-A2-s2.0-0029538462https://www2.scopus.com/inward/record.uri?eid=2-s2.0-0029538462&doi=10.1016%2f0961-9526%2895%2999801-A&partnerID=40&md5=f7366312de777f0e813424d15c51758b
