Abstract
In the new era of industrial revolution of 4.0, additive manufacturing (AM) technique gains attention from academia, researchers and industries. Fabrication of Polylactic Acid (PLA) honeycomb core using 3D printing technique was employed in this study via fused deposition modelling (FDM). Two types of sandwich composites were fabricated between carbon fibre face sheet with printed PLA core (C/PLA) and Nomex honeycomb core (C/NMX) via hand lay-up and vacuum bagging processes. Compression tests were conducted in the flatwise and edgewise directions according to the ASTM C365 and ASTM C364, respectively. It was found that the C/PLA exhibited higher on the compression stresses both in the flatwise and edgewise directions as compared to C/NMX. Tested sample of C/PLA displayed the flatwise and edgewise compression stresses of 25.7 and 125.0 MPa, while the tested sample of C/NMX exhibited the value of 7.9 and 12.6 MPa, respectively. In terms of compression strain, it was observed that C/PLA exhibited 31.5% higher than C/NMX in the flatwise direction.
