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

摘要

Influence of graphite microparticles on the static tensile strength (σ_m, σ_B, ε_M, ε_B and E), impact strength (u_C), and mass melt flow rate (MFR) of composites including a poly(ε-capro-lactone) 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 (σ_M) and the longitudinal modulus of elasticity (E) and the decrease in the tensile strain at break (ε_B), Charpy impact strength (u_C), and melt mass-flow rate (MFR).
