Characteristic investigation of carbon/ceramic-based functionally graded multilayered composite materials

This research article focused on 3D-printed multilayered polymer composite materials, with a particular emphasis on ceramic and carbon polymer composite materials. To evaluate the mechanical performance of a multilayered composite structure, ceramic polymer composite (CPC) materials were used layer by layer with carbon-reinforced polymer composite (CRPC) layers. Tensile, compression, flexural, and differential scanning calorimetry tests were carried out on 3D-printed CPC, CRPC, and Functionally Graded Multilayered Material (FGMLM) composite structures. The results indicated that FGMLM laminates exhibited increases of 12.4%, 6.4%, and 9.8% in tensile, flexural, and compressive strength, respectively, compared with CRPC laminates; these experimental values were validated by finite element analysis. Further, fractography analysis of the FGMLM was carried out using scanning electron microscopy to provide insights into the structural characteristics. It was indicated that strong interfacial bonding was found between the laminated carbon and ceramic layers.
