Transverse modulus measurement of carbon fibre by atomice force microscope and nanoindentation
Paper in proceeding, 2019

Carbon fibre reinforced polymer composite has been widely used in structural component due to the high specific axial modulus of carbon fibre. However, the transverse Young’s modulus is much lower and not well studied because of the extremely small diameter (~5 μm). In this work, flat test surfaces on carbon fibre IMS65 were fabricated using focused ion beam. The transverse Young’s modulus was measured by nano-scale indentation tests, which were performed on fabricated flat surfaces, using both atomic force microscopy and nano-indentation. The surface damage induced by the high energy ion beam was also assessed.
