Comparative investigation of tensile strength and hardness of novel aluminium oxide powder blended GFRP and banana fibre blended GFRP with plain GFRP.

The purpose of this study is to investigate the effects of using new banana fibre and aluminium oxide as natural fillers in glass fibre reinforced polymer (GFRP). Substances and Techniques: Using a hand lay up approach, we create polymer composites in three groups (two experimental and one control). Twenty samples were taken from each group. The hardness is tested using a Barcol Hardness Machine, while tensile strength is determined by a Universal Testing Machine (UTM) (BMU). Tensile strength is measured using ASTM-D638 and hardness is measured using ASTM-D785. There were sixty people in total in the sample. G power test was performed to determine the optimal sample size for each group; these values were 80%, 5%, and 95%, respectively. Using SPSS-V26, we found that the findings were statistically significant at the 0.000 p0.05 level. The tensile strength of GFRP reinforced with aluminium oxide and unique banana fibre was found to be substantially greater than that of GFRP. In comparison to GRFP, the unique banana fibre GRFP and aluminium oxide blended material's hardness was noticeably greater. Results showed that compared to untreated GFRP, the tensile strength and hardness of composites made with alkaline-treated natural fillers such as aluminium oxide and unique banana fibre were significantly improved.
