“…The effect of microfiber/matrix interface on mechanical properties of composites has been widely explored [1e7]. Several established methods, including the push-out test [6,8], the pull-out test [9e11], the microbond test [12,13], the microindentation test [14,15], and the fragmentation test [7,16,17], etc, have been employed to characterize the interfacial strength. For example, Rebillat et al used push-out tests to investigate the interface and interphase characteristics of strongly bonded twodimensitonal (2D) SiC/C/SiC composites [5].…”
