Abstract

In the present paper, epoxy resin based composite materials with nanosize diamond (graphite cluster diamond, GCD) added to constitute 0 - 5 vol.-% were prepared, with the aim of developing a solid lubricating composite material using epoxy resin as the matrix. The material's mechanical properties and friction coefficient were measured. Density measurement showed that the compacted GCD dispersed epoxy resin based composite had a relative density of 1·0. The bending modulus of elasticity remained constant, regardless of changes in the GCD content; however, the bending strength dropped rapidly as the volume fraction of the GCD was increased. The addition of GCD to the matrix system reduced the friction coefficient.
