N2 - Short beam strength (SBS) testing is often conducted on new fiber reinforced polymer composite materials that can be limited in sample size, including fiber composites with secondary carbon nanotube (CNT) reinforcement. However, unlike Mode I and Mode II interlaminar fracture tests, which require larger samples, interlaminar shear strength values obtained from SBS tests are insensitive or weakly sensitive to CNT content and therefore do not provide much insight into the potential effectiveness of CNT reinforcement. In this work, load-displacements plots from SBS tests were analyzed in detail to better understand the effect of CNTs on the interlaminar mechanical behavior of carbon/epoxy laminates.
