Utilizing in-nozzle impregnation for enhancing the strength of recycled PET-derived 3D printed continuous banana fiber reinforced bio-composites
Abstract
<jats:sec><jats:title content-type="abstract-subheading">Purpose</jats:title> <jats:p>This study aims to evaluate the potential of using the in-nozzle impregnation approach to reuse recycled PET (RPET) to develop continuous banana fiber (CBF) reinforced bio-composites. The mechanical properties and fracture morphology behavior are evaluated to establish the relationships between layer spacing–microstructural characteristics–mechanical properties of CBF/RPET composite.</jats:p> </jats:sec> <jats:sec><jats:title content-type="abstract-subheading">Design/methodology/approach</jats:title> <jats:p>This study uses RPET filament developed from post-consumer PET bottles and CBF extracted from agricultural waste banana sap. RPET serves as the matrix material, while CBF acts as the reinforcement. The test specimens were fabricated using a customized fused deposition modeling 3D printer. In this process, customized 3D printer heads were used, which have a unique capability to extrude and deposit print fibers consisting of a CBF core coated with an RPET matrix. The tensile and flexural samples were 3D printed at varying layer spacing.</jats:p> </jats:sec> <jats:sec><jats:title content-type="abstract-subheading">Findings</jats:title> <jats:p>The Young’s modulus (E), yield strength (sy) and ultimate tensile strength of the CBF/RPET sample fabricated with 0.7 mm layer spacing are 1.9 times, 1.25 times and 1.8 times greater than neat RPET, respectively. Similarly, the flexural test results showed that the flexural strength of the CBF/RPET sample fabricated at 0.6 mm layer spacing was 47.52 ± 2.00 MPa, which was far greater than the flexural strength of the neat RPET sample (25.12 ± 1.94 MPa).</jats:p> </jats:sec> <jats:sec><jats:title content-type="abstract-subheading">Social implications</jats:title> <jats:p>This study holds significant social implications highlighting the growing environmental sustainability and plastic waste recycling concerns. The use of recycled PET material to develop 3D-printed sustainable structures may reduce resource consumption and encourages responsible production practices.</jats:p> </jats:sec> <jats:sec><jats:title content-type="abstract-subheading">Originality/value</jats:title> <jats:p>The key innovation lies in the concept of in-nozzle impregnation approach, where RPET is reinforced with CBF to develop a sustainable composite structure. CBF reinforcement has made RPET a superior, sustainable, environmentally friendly material that can reduce the reliance on virgin plastic material for 3D printing.</jats:p> </jats:sec>
