An investigation to compare water absorption behaviour of novel coconut shell powder filled Glass/Kapok fiber reinforced epoxy composite with glass/kapok fiber reinforced epoxy composite.

This study aims to explore the water absorption characteristics of a composite material consisting of glass and Kapok fibres, both with and without the incorporation of a revolutionary coconut shell powder. The substance in question is a composite material. The Constituents and the Methods involved: Twenty samples are included in the experimental group, which is comprised of a glass/Kapok fibre composite that has been reinforced with new coconut shell powder at a concentration of twenty percent. For the purpose of this experiment, the control group is comprised of twenty samples of a Glass/Kapok fibre epoxy composite. The total number of people who took part in this research project equals forty. The determination of the sample size for this study is accomplished by utilising the G power calculator. The GPower is set at 80 percent, and the α value is set at 0.05 for each group. In order to manufacture the composite, the hand lay-up method was utilised as the production method. The results of the experimental research led to the conclusion that the Glass/Kapok fibre reinforced composite has a water absorption of 8.2385 grammes, whereas the Glass/Kapok fibre epoxy composite that contains 20 percent new coconut shell powder has a low water absorption of 7.5345 grammes. This conclusion was reached based on the findings of the research. The study revealed that there was a statistically significant difference between the two groups, as demonstrated by the p value of 0.001 (p<0.05). This was confirmed by the fact that the p value was less than 0.05. It was demonstrated that Glass/Kapok fibre composites that contained 20 percent volume fraction coconut shell powder displayed a lower level of water absorption in comparison to Glass/Kapok fibre composites that contained coconut shell powder. This was in light of the limitations that were imposed by this research. [ABSTRACT FROM AUTHOR]
