Abstract:
We investigated the influence of interlayer sp3 bonds on the mechanical properties, such as Young’s modulus, shearing
modulus, and tensile strength of single-crystalline graphite with the orientation angle of 0° and quadruple crystalline graphite with the orientation angle of non-zero degree. It was found that interlayer sp3 bonds increase the shearing modulus between layer-planes. In addition, it was found that interlayer sp3 bonds in a crystallite with the orientation angle of 0° decrease the tensile strength, whereas those in a crystallite with the orientation angle of 45° increase the tensile strength and Young’s modulus.
