PLA reinforced with short carbon fibers showed the highest tensile strength of 50.83 MPa at a 45°/-45° orientation, enhancing its mechanical performance.
The study found that PLA-GF had superior flexural strength of 17.79 MPa at a 0°/90° orientation while achieving excellent fracture resistance metrics like KIC.
Analysis involved standardized ASTM tests alongside thermogravimetric analysis and scanning electron microscopy to evaluate properties comprehensively.
These findings underscore the importance of fiber type and printing direction for optimizing the mechanical attributes of 3D-printed composite materials.
