REINFORCEMENT OF 3D PRINTED PLA WITH CARBON FIBER REINFORCED COMPOSITE AND INVESTIGATION OF MECHANICAL PROPERTIES

While production methods with 3D printing are developing day by day, studies on this method are also increasing. 3D layered manufacturing is a method of creating layer-by-layer 3D solid models designed with computer-aided drawing (CAD) programs using melted raw material for each layer. In addition to PLA being the most commonly used filament in 3D printing, filaments such as ABS, PETG, and TPU are also used. A wide variety of products can be produced with this production method depending on the design. The mechanical properties of the products resulting from 3D printing depend on many parameters such as the number of layers, fill rate, material used, and printing speed. Various methods are also applied to further strengthen the products produced from printing. In this study, PLA samples obtained from 3D printing were reinforced with carbon fibre reinforced polymer composite (CFRP). The reinforcement process was carried out by placing CFRP material during PLA sample production, and the mechanical properties of the resulting samples were examined. Increased hardness as well as improved tensile, bending, impact, and wear strengths of the CFRP reinforced samples were observed
