Continuous Fiber-Reinforced Material Extrusion with Hybrid Composites of Carbon and Aramid Fibers

An existing challenge in the use of continuous fiber reinforcements additively manufactured parts is limited availability suitable materials. This leads to a reduced adaptability mechanical properties load case. The increased design freedom additive manufacturing allows flexible deposition strands at defined positions, so that even different materials can be easily combined printed part. In this work, therefore, an approach taken combine carbon and aramid fibers composite investigate their effects on properties. For purpose, tensile, flexural impact tests were performed made nylon matrix with five mixing ratios. showed hybrid composites for reasonable adapt loading case hand. experiments increasing content resulted increase strength, but decrease tensile strength stiffness. Microstructural investigations fracture surfaces debonding delamination main failure mechanisms. Finally, Rule Hybrid Mixture equations applied predict mixture predicted values differed from experimentally determined by average 5.6%.
