Abstract

This paper presents an experimental investigation of Mode I interlaminar fracture toughness of 3D printed Onyx specimens using the Double Cantilever Beam (DCB) test as per ASTM D5528. Two specimens of thickness 3.85 mm and 6.0 mm were fabricated using fused filament fabrication and tested under tensile opening loading. Load displacement response and crack propagation were recorded to determine the critical strain energy release rate (GIC). The specimen with 6.0 mm thickness exhibited higher fracture toughness (32,132 J/m2) compared to 15,370 J/m2 for the 3.85 mm specimen. The results indicate that increased thickness improves resistance to delamination in 3D printed Onyx components.
