Aim :The focus of this research is to analyse the hardness of Sisal/Ramie/Pineapple fibre composite pipe reinforced by adding of silica nanoparticles for High fluid pressure transfer applications. Materials and Methods: Hand lay-up was used to create the epoxy Sisal/Ramie/Pineapple fibre composite with and without silica nanoparticles. The nano silica particles were heated to 60 degrees Celsius before being utilised as reinforcement. For composite fabrication, 4wt% of new heat-treated nano silica particles were employed. A barcol hardness test was used to determine the composite's hardness. Each plate of the experimental group (containing nano silica particles) and the control group had test samples (N = 20) collected from it (without nano silica particles). The sample size for the control and experimental groups was calculated using 80% of the total pretest G power in this study. G Power is taken as 80%. Results:The hardness of the unfilled composite was determined to be lower than the silica nanoparticles filled composite after a one-way SPSS using SPSS software with a significant level ofshowed statistical significance p=0.023 (p﹤0.05). With a significance value of, the Hardness test of filler-filled laminates is 3.2 percent higher than that of filler-free laminates. Conclusion: Within the limitations of this study, the hardness of Sisal/Ramie/Pineapple fibre with filler is influenced by the infusion of a novel preheated nano silica nanoparticles with the resin, which affects the quality of the final product and its thickness, with higher hardness 4% than samples generated without filler at 5.6.
