Nanodiamond (ND), a carbon-based nanoparticle having sp3 hybridization, has high hardness, excellent chemical stability and thermal conductivity and a typical average diameter of 2−10 nm. The outer surface of ND is originally covered by many functional groups such as hydroxyl, carboxyl, and ketone, which makes ND surface adapted for functionalisation without compromising its core properties. The spherical shape of ND (entanglement-free nanoparticle) with high interfacial area, as compared to platelet shape of graphene and tube like shape of CNT, and rich surface chemistry along with high mechanical properties makes it a promising candidate as reinforcement in structural composites.The present study reports the effect of ND as reinforcement to epoxy matrix, in terms of the mechanical (elastic modulus, hardness, fracture strength) and tribological properties of the composite. The potential of ND is being investigated here as a reinforcement for light weight high strength structural composite.
