Abstract

Employment of natural fber for the flament of fused deposition modeling (FDM) can be found in numerous studies from diferent areas. However, the presence of fber such as kenaf in polymer flament could cause mechanical properties degradation with regard to the fber loading owing to low compatibility between natural fber and polymer matrix. Therefore, this study aims to study the mechanical properties of three-dimensional (3D)-printed structures of composites specimens with varying volume percentages of kenaf fber. From the tensile and fexural testings, the fndings revealed decrements in the tensile strength and modulus of kenaf fber-reinforced ABS (KRABS) composites from 0 to 5% contents of kenaf fber which were 23.20 to 11.48 MPa and 328.17 to 184.48 MPa, respectively. The raising amount of kenaf fber at 5 to 10% raised the tensile strength and modulus from 11.48 to 18.59 MPa and 184.48 to 275.58 MPa, respectively. Flexural strength and modulus of KRABS composites were decreased at to 5% from 40.56 to 26.48 MPa and 113.05 to 60 MPa, respectively. With further kenaf fber addition from 5 to 10%, the fexural strength and modulus were increased from 26.48 to 32.64 MPa and 60 to 88.46 MPa, respectively. These results were supported by the fnding from the morphological analysis, where the presence of porosity and fber pull out implied the poor interfacial bonding between kenaf fber and ABS matrix. This study has successfully demonstrated the tensile and fexural performances of diferent volume percentages of KRABS composites flament for FDM through experimental research.
