Development and assessment on hemp–carbon–basalt fibre base hybrid composite with organic fillers for structural applications

Hybrid composites are in increasing demand for structural applications. The created composite material is anticipated to possess fundamental qualities and a typical load-bearing capacity. The development of a hybrid composite hemp-epoxy polymer material with carbon and/or basalt fiber reinforcement is proposed in this study. With carbon fiber at 6%, basalt fiber at 6%, and carbon-basalt at 2 + 4% in the reinforcement, the weight percentage of the fiber reinforcement was altered for 15, 20, and 25% of hemp fiber in the composite. Additionally, natural fillers like coconut shell powder and calcium carbonate were incorporated into the matrix material. To create the composite with various combinations of fiber reinforcement, industrial standards processes were followed. In comparison to other compositions, the hemp-carbon fiber sample (A3) has a maximum strength of 104 MPa. The same composition also has a maximum stiffness of 197 N/mm, which may be attributed to the matrix material’s high bonding strength (67 weight percent). The shore hardness of the hemp-carbon fiber composite is likewise at its highest, falling between 90 and 98 on the hardness scale. The results revealed that composites composed of carbon and hemp fibers have superior mechanical characteristics to basalt fiber reinforcement. To investigate the material behavior, an electron microscope will be used to examine the cracked surfaces. The material will be suggested for use in structural applications based on the findings.
