Interlaminar Shear Strength of Multi-walled Carbon Nanotube and Carbon Fiber Reinforced, Epoxy – Matrix Hybrid Composite

Studies have been carried out to evaluate interlaminar shear behavior of carbon nanotube and carbon fiber reinforced, epoxy matrix hybrid composite. Short beam shear (SBS) tests were conducted to characterize the influence of fiber orientation in the interlaminar shear strength (ILSS). Experimental details, specimen configuration, data acquisition, and processing are presented in detail. The present study reveals the importance of the alignment of fiber and its effects on ILSS properties and the nature of deformation under shear loading conditions. The results show that the interlaminar shear strength of the hybrid composite is significantly
higher in longitudinal orientation as compared to the same in transverse orientation, and more importantly, show that such anisotropy is of an order of magnitude and higher
