MECHANICAL BEHAVIOR OF NANODIAMOND/EPOXY NANOCOMPOSITES

摘要

The mechanical properties of epoxy-based nanocomposites reinforced by nanodiamond (ND) particles were investigated. The results showed that while the addition of 0.1 wt% of ND improved the Young's modulus and tensile strength compared with those of the pure epoxy, the mode I fracture toughness did not show any improvement. Furthermore, in order to study the effect of shear deformation on fracture properties of nanocomposites, mixed mode fracture resistance of nanocomposites was investigated. It was found that as the share of shear deformation in mixed mode loading increases, the positive effect of ND particles enhances.
