Abstract Scope |
This study investigates the feasibility of replacing conventionally manufactured aerospace bolts with topology-optimized Ti-6Al-4V bolts produced via Laser Powder Bed Fusion (LPBF), as a case study for enhancing supply chain resilience. A solid baseline and three weight-reduced variants (2.5%, 5%, 10%) featuring internal gyroid lattices were fabricated and tensile-tested per NASM1312-8. Mass reduction and dimensional accuracy were evaluated using precision scales and X-ray computed tomography. Performance was compared to machined Ti-6Al-4V bar stock bolts. While the optimized designs retained near-comparable tensile strength among LPBF variants, they showed significant reductions relative to bar stock. The results highlight the need for careful process control and deeper engineering insight when substituting traditional parts with AM alternatives. |
