Measurement of the mechanical and dynamic properties of 3D printed polylactic acid reinforced with grapheneMeasurement of the mechanical and dynamic properties of 3D printed polylactic acid reinforced with graphene Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2020-05-282019enIn this paper, three-dimensional (3D) printing system based on fused deposition modeling (FDM) is used for the fabrication of polylactic acid (PLA) specimens with and without graphene and to measure their dynamic mechanical properties. In particular, 3D printed PLA/graphene nanocomposites containing 10wt% graphene in PLA matrix were characterized by compression tests, cyclic compression tests, nanoindentation and modal tests. The results of the mechanical tests reveal that the incorporation of multifunctional graphene has improved the modulus, the strength and the hardness of the 3D printed nanocomposites. The damping as calculated by cyclic compression and modal tests was substantially increased compared to neat PLA samples.http://creativecommons.org/licenses/by/4.0/Polymer-Plastics Technology and Materials58111234-1244 Mansour Misel-Teontor Μανσουρ Μισελ-Τεοντορ Tsongas Konstantinos Tzetzis Dimitrios Taylor & Francis 3D printing Additive manufacturing Compression Damping Fused deposition modeling Graphene Indentation tests Mechanical properties Modal tests Polylactic acid
