Impact Analysis of Fiber Volume Ratio on Physical & Mechanical Properties of Natural Fiber Composites

Abstract

Natural fibers derived from renewable resources have the potential to serve as a reinforcing component in the production of composites. This study aids in understanding how, when fiber length was kept constant and randomly orientated, the specimen's physical and mechanical properties were affected by the fiber volume ratio. When creating composite samples, phenol-formaldehyde was employed as an adhesive material. In a predetermined ratio, jute, hemp, and coconut fibers are used for the research project. All of the samples in this investigation had a fixed fiber length, randomly oriented fibers, and a 5 mm thickness. The fibers had a 12mm length. The samples were created using the hand lay method, and according to their volume ratio, they have been classified as S1, S2, S3, and S4. Depending on the specimens created, the fiber volume ratios ranged from 30% to 60%. For S1, S2, S3, and S4 specimens, the fiber volume ratio was 30%, 40%, 50%, and 60%, respectively. In the prepared specimens, various physical and mechanical tests have been carried out following the standards. Flexural strength and Tensile strength of the composite were found to be at their maximums at 60% fiber ratio (S4) inside the composite (S4). The investigation into how fiber ratio affects mechanical and physical qualities came to an end with this.
