The strength of the reinforcement/matrix interfaces plays a crucial role in determining the operating deformation and failure mechanisms of metal matrix composites (MMCs). Here, we conducted in situ micro-tensile tests on nanolaminated single-walled carbon nanotube (SWCNT)-aluminum (Al) composite micro-pillars of different laminate orientations. Both the composite strength and its deformation mechanism showed strong anisotropy, and the SWCNT/Al interfacial normal and shear strengths were measured to be 254.9 ± 9.3 MPa and 112.8 ± 3.5 MPa, respectively, which governed the fracture mode of the composite micro-pillars.
