Investigation of mechanical behavior of carbon fiber reinforced PA composites produced by melt deposition method

With the development of technology, the demand for three-dimensional (3D) printings technologies has increased with the changing and developing production methods. Its importance has gradually increased and gained popularity due to the fact that complex geometries can be manufactured in one go without requiring a separate process, it is computer aided, and it saves time and waste materials. One of the most preferred production methods in these 3D printing technologies is Fused Deposition Modeling (FDM). With this method, the production of composite materials has become widespread. Especially considering that carbon fiber reinforcement increases the mechanical behavior of composite materials and other advantages it provides, it has become a necessity in many sectors. The aim of this study is to determine the mechanical behavior of Polyamide (PA) and carbon fiber reinforced PA-CF composite materials printed with FDM with the help of both experimental and analysis and to determine the advantages of carbon fiber reinforcement on the mechanical behavior of PA materials. In this direction, test specimens in accordance with ASTM standards were produced by using FDM method using PA filament and carbon fiber reinforced PA-CF filament. Tensile, compression and three-point bending tests were carried out to determine the mechanical behavior of the produced samples. The obtained results were analyzed in the ANSYS Workbench program. As a result of the experiments and analysis, it was observed that carbon fiber reinforcement mechanical behavior of the composite material in a positive way.
