Evaluation of composites interphase mechanical properties considering CZM and FGM behaviors using single-fiber composite tensile tests (opens in new tab)

The mechanical behavior of the matrix–fiber interphase plays a critical role in the performance of composite materials, as damage often initiates and propagates from this region. This study combines experimental and numerical approaches to investigate the interphase mechanical properties between glass fibers and epoxy matrix using specially designed single-fiber composite specimens. Tensile tests are performed at a low loading rate, and the obtained elastic responses are matched to those calc...
