Mechanical and thermal characterization of additively manufactured novel multilayer polymer composite through experiments and finite element simulation

This study presents the investigation of mechanical and thermal properties of additively manufactured novel multilayer composites (MLC). Wood and carbon-reinforced poly-lactic acid were used as the base materials for the 3D printing of the MLC. The tensile, compressive, and flexural strengths of the developed MLC were 51.47, 70.90, and 73.3MPa, respectively. The finite element simulation values of tensile and compressive strength of the MLC were 51.01 and 70.02MPa depicting negligible variations of 0.90% and 1.24%. The glass transition temperatures for the WRP, CFRP, and MLC specimens were 54.85 degrees C, 57.29 degrees C, and 56.78 degrees C, respectively.
