Dynamic mechanical properties of copper-ABS composites for FDM feedstock

This paper presents an investigation of dynamic mechanical properties of a copper-ABS composite material for possible fused deposition modeling (FDM) feedstock. The material consists of copper powder filled in an acrylonitrile butadiene styrene (ABS). The detailed formulations of compounding ratio by volume percentage (vol. %) with various combinations of the new polymer matrix composite (PMC) are investigated experimentally. Based on the result obtained, it was found that, increment by vol. % of copper filler ABS affected the storage modules (E') and tan δ results. The storage modulus and tangent delta increased proportionally with increment of copper filled ABS. It can be observed that, the storage modulus and tangent delta are dependent on the copper filled ABS in the PMC material.
