| Abstract Scope |
Short carbon fiber-reinforced polymer composite materials produced using Large Area Additive Manufacturing (LAAM) have garnered significant attention due to their superior properties. However, the physical and mechanical properties of the additively manufactured composite parts often fall below expectations due to void formation and uncontrolled fiber orientation within the microstructure. To address this issue, this study aims to investigate the effect of bed temperature on the microstructure of single and multilayer beads of Short Carbon Fiber reinforced Acrylonitrile Butadiene Styrene (SCF/ABS) manufactured via the LAAM system. This study employs high-resolution 3D micro-computed tomography (µCT) to evaluate the fiber orientation, void shape, size, and distribution within the microstructure of the SCF/ABS composite parts. Preliminary results indicate that increasing the bed temperature significantly reduces the size of voids and leads to a uniform void distribution and fiber orientation within the microstructure of the manufactured polymer composites. |
