This study focuses on the development of carbon fabric-reinforced polymer composites which were prepared using polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS) blends (10, 30, and 50 wt%) with different compatibilizers. For this purpose, styrene-ethylene-butylene-styrene terpolymer grafted with maleic anhydride (SEBS-MAH), ethylene-glycidyl methacrylate copolymer (E-GMA), styrene-maleic anhydride (SMA), and styrene-acrylonitrile-glycidyl methacrylate (SAN-GMA) were added with concentrations of 5, 10, and 15 wt% using a co-rotating twin screw extruder. The polymer layers of multilayer composites were prepared with neat PLA, 70PLA/30ABS and 10SAN-GMA/(70PLA/30ABS), and reinforced with one and three layers of carbon fabric (CF) using compression molding process. The characterization results reveal that tensile strength of 70PLA/30ABS blend was 40% higher than other binary blends. Among the ternary blends, the maximum impact strength of 27.0 kJ/m2 was achieved with the addition of 10 wt% SAN-GMA into PLA/ABS blends. Three layered CF composites showed higher mechanical performance than one layered CF composites. While multilayer composites of neat PLA-3CFs had the highest tensile modulus, 70PLA/30ABS-3CFs composites exhibited the highest tensile strength among the other composites.
