Additive manufacturing technologies have been successfully applied in various applications of aerospace, automotive and sports industries. The increasing need for prototyping and customization of fiber reinforced composites is prompting innovations in new manufacturing processes to achieve short manufacturing cycle time and low production cost which is challenging to accomplish using conventional molding process. One of extrusion based manufacturing process named fused deposition modeling (FDM) holds promise to achieve low cost production. But parts fabricated by fused deposition modeling have lower strength. So it cannot be used for functional requirement. The strength of FDM fabricated part is increased by using fiber reinforcement. In this work carbon fiber reinforcement in two different matrix materials ABS and PLA is investigated. Carbon fiber reinforcement in dual material composite is also investigated. Effect of number of fiber rovings, material, structural arrangement and heat treatment on tensile strength and elongation of part is investigated. Fiber reinforced part gives higher tensile strength than pure thermoplastic part. Elongation is dependent on matrix material. For fiber reinforcement in ABS elongation is decreased after fiber reinforcement. While for fiber reinforcement in PLA elongation is increased after fiber reinforcement. Fiber reinforcement and heat treatment give positive influence on tensile strength of part. ABS-PLA-ABS is better structural arrangement than PLA-ABS-PLA structural arrangement for dual material composites. This investigation also provides guidance for future investigations of fabricating carbon fiber reinforced composites by AM techniques.
