Processing and mechanical properties of poly(ε-caprolactone)/graphite composites

Influence of graphite microparticles on the static tensile strength (sigma(M), sigma(B), epsilon(M), epsilon(B) and E), impact strength (u(C)), and mass melt flow rate (MFR) of composites including a poly(epsilon-caprolactone) matrix was investigated. The composites with graphite content from 0 to 50 wt. % were prepared. It was found that the increase in the graphite fraction caused the increase in both the static tensile strength (sigma(M)) and the longitudinal modulus of elasticity (E) and the decrease in the tensile strain at break (epsilon(B)), Charpy impact strength (u(C)), and melt mass-flow rate (MFR).
