摘要

The feeding angle is described in relation to the mechanical behavior of composites reinforced with polyamide 6 and short carbon fibers. The Polyamide 6 (N) and Polyamide 6 composites (NC) that contained 20 weight percent short carbon fiber were taken into consideration for the study. Using fused deposition modeling, these composites were created. 0°, 30°, 45°, and 60° are the four orientations in which the material has been placed. These composites’ tensile, flexural, and impact qualities were examined in accordance with ASTM guidelines. The thermal behavior and the moisture absorption characteristics were studied. It is observed that the mechanical behavior was superior for 00 feeding direction. Further, the effect of 60° feeding exhibited the least behavior among the composites studied. This may be due to the maximum interfacial shear stress at 45° to the shear plane. Further, the matrix fiber interface was effectively developed during fused deposition. Thermal stability was enhanced due to the additive process and reinforcement phase. This may be due to the superior degree of crystallinity and fusion. The heat deflection temperature and the melt flow index were explored to add strength to the 3D printing process. The acceptable percentage of void fraction has made the composites exhibit better properties in all respects. SEM pictures were used to examine the cracked surfaces.
