摘要

Combining characteristics of two different materials offers improved performance in numerous applications. Innovative material (IM) is one such heterogeneous material fabricated through additive manufacturing (AM) technique by depositing poly lactic acid (PLA: M-1) and ceramic PLA (M-2) in alternate layers. Lightweight, heat resistance, and improved strength obtained from combining the characteristics of M-1 and M-2 are effectively superimposed in IM. A single edge notch bend (SENB) test is used to study the fracture behavior of the considered materials and assess its mode I fracture toughness (KIC) by means of experimentation and numerical simulation. Experimental values of KIC are obtained as 5.72 MPa√m, 6.8 MPa√m, and 11.54 MPa√m for M-1, M-2 and IM.  The strong correlation between experimental and simulation results indicates that IM has a stronger fracture resistance than M-1 and M-2, suggesting that it could replace metals in lightweight applications. This encourages the effective use of IM structures in aerospace, automotive, and architectural industries where fracture resistance is crucial.
