Experimental characterization of 3D printed nylon-carbon at different strain-rates

Three-dimensional printing technology using fused deposition modeling processes is becoming more and more widespread thanks to the improvements in the mechanical properties of materials with the addition of short fibers into the polymeric filaments. Nowadays, it is possible to create components with mechanical properties such that they can be used under high loads. The prediction of the mechanical response of printed components is crucial in the design phase and requires the mechanical characterization of the material under various loading conditions depending on the applications. In the present work, the strain-rate sensitivity of nylon reinforced with short Carbon fibers has been investigated by tensile tests on fulfilled dog-bone specimens.
