Abstract

This research focuses on developing an innovative material through the layer-by-layer alternating deposition of polylactic acid (M1) and a wood polymer (M2) using the fused deposition modeling (FDM) process, with an emphasis on evaluating its fracture toughness. The primary aim is to enhance composite’s fracture resistance by utilizing the distinct properties of each material within a multilayered structure. Mode I fracture toughness is experimentally assessed using linear elastic fracture mechanics. The results indicate that the fabricated material demonstrates superior fracture toughness (K_IC = 8.5 (Formula presented.)) compared to M1 (K_IC = 5.74 (Formula presented.)) and M2 (K_IC = 3.84 (Formula presented.)), reflecting an increase of more than twice the average K_IC of M1 and M2. Additionally, numerical simulations are performed in ABAQUS CAE using the extended finite element method to support experimental findings.
