Abstract (EN): Carbon fiber reinforced plastic composite thin ply laminates are reinforced in interlaminar regions with vertically-aligned carbon nanotubes (A-CNTs) using a technique known as ¿nanostitching.¿ In this study, we report the successful interlaminar nanostitching of thin ply laminates and the reinforcing effects associated with the addition of A-CNTs. Testing under short beam shear loading configuration yields a 17% improvement in the interlaminar shear strength of thin ply laminates as compared to the equivalent thick laminate and an additional 3% improvement after nanostitching. In situ double edge notched tensile testing, which generally demonstrates a reduced damage state for thin ply vs. conventional thickness plies, exhibits minimal damage accumulation and progression with increasing tensile load as visualized using synchrotron radiation computed tomography (SRCT). Although the effect of nanostitching was not clearly distinguished in the in situ tensile tests, these results are an initial outlook via in situ microtomographic volume imaging on the synergetic effects of nanostitching and thin ply morphologies on the failure progression of aerospace-grade unidirectional laminated composites.
