摘要:
This paper presents the results of experimental analyses of the static and dynamic behavior of bio-sourced conventional and auxetic architectural materials. Three different configurations were studied. The specimens were made with the technology of additive manufacturing (3D printing) and were made of the same material which is polylactic acid reinforced with flax fibers (PFF). Several tensile tests were performed on four relative densities for each configuration of the composite to understand their influence on the static behavior of the material. Taking into account the insufficiency of the static tests to correctly predict the behavior of the composite, vibration tests were carried out on the same densities and composite configurations. The focus will be mainly on the study of the influence of the 2D lattice structures for each density on the evolution of the dynamic stiffness and damping properties.
