dc.description.abstractThis study investigates the mechanical and joint properties of the carbon fiber powder (CFP) reinforced polylactic acid (PLA) manufactured by 3D printing process. Composite filaments with various contents of CFP (5 wt.%, 10 wt.% and 15 wt.%) were prepared using a single screw extruder. Adherends and tensile test specimens were printed by an open-source 3D printer. Polyethylene oxide (PEO) was used as a plasticizer to improve the ductility of the PLA and PLA/CFP composite. Experimental results revealed that the CFP considerably improved the mechanical properties and the joint strengths of the composite specimens. Incorporating PEO into the blends enhanced ductility for both tensile and joint specimens but reduced strength. The SEM images showed that the fiber/matrix adhesion is weak. However, the parallel orientation of the fibers to the load direction together with their uniform distribution in the matrix increased the mechanical properties of the composites. SEM observations also showed that the addition of PEO caused porous matrix structure which is responsible for the increase in ductility of the PLA and its composites. Global yielding (G.Y) criterion was used to predict the joint failure loads and a comparison was made between experimental and predicted failure loads. The comparisons showed that the G.Y criterion over-predicted the failure loads. The minimum and maximum difference between experimental and predicted failure loads were 12.96% and 28.10%, respectively. At last, recommendations for further studies were also presented.en_US
