| Abstract Scope |
Fiber bundles in both natural and engineered systems demonstrate impressive mechanical characteristics such as strength and flexibility. However, little has been done to abstract their underlying design principles for additive manufacturing. To address this gap, this research developed an adaptable parametric design program capable of generating an extensive variety of 3D fiber bundle models. This program enables modeling of key structural parameters in fiber bundles, including the number and configuration of fiber strands, strand heights, the degree of strand twist, and individual fiber occupancy. To empirically validate these digitally derived designs, the generated 3D models were manufactured using Selective Laser Sintering (SLS) 3D printing and subjected to a range of mechanical tests (tension, compression, bending and torsion) to determine properties including compliance, strength, and energy absorption. Results, while limited, show promise for achieving material property design spaces beyond those of traditional cellular materials. |
