Structural Integrity and Elasticity of Banana Fibre Effect of Blast Pressure: Understandings from Strain Test Comparisons Before and After Blast Test

The purpose of this study is to analyse the structural integrity and elasticity of banana fibre that has been subjected to the blast effect. To accomplish this evaluation, strain tests are done before and after the blast test. The finding that the material's tensile strength was greatly enhanced was one of the most important findings that was made. As a result of being treated with a 400g blast, the pressure reached 12,482.57 MPa, but when 800 g blast, the pressure reached 24,965.15 MPa. During the tensile tests, for the sample 400 g, the maximum force was 64.81 N, and the stress was 2.16 N/mm². Sample 400 g had a maximum force of 137.61 N and a stress of 4.59 N/mm². The strain test results showed that 400 g had a maximum stroke of 1.59 mm and a strain value of 2.45%. Besides, 800 g has a maximum stroke of 0.83 mm and a strain value of 1.27%. The data thermocouple indicates that the temperature sample is 400 g, reaching a maximum temperature of 39.68°C. When it reached its greatest point, the temperature of 800 g was 38.12 °C. Based on the results of this experiment, it can be concluded that the fibre exhibited higher levels of strength and resilience when it was subjected to conditions that needed a greater amount of blasting.
