Determining the Potential of Layered Banana Fibre Weave Patterns for Enhanced Blast Resistance in Bomb Blankets

2025-06-10 , Abdul Rashid Othman , Ahmad Humaizi Hilmi , Asna Rasyidah Abdul Hamid , Siti Aisyah Azman

The banana fibre is part of research aimed at creating materials for weaving bomb blankets. To determine whether plain and intra-ply woven banana fibre designs are feasible and effective in enhancing blast resistance, the primary purpose of this research is to analyse the practicability and efficiency of these designs. The method begins with extracting banana fibres, followed by applying an alkali treatment to enhance the mechanical properties of the fibres, and finally concludes with weaving the fibres into plain and intra-ply patterns. The scanning electron microscopy (SEM) technique was utilized to analyse the surface morphology and assess any damage that occurred as a result of the blast. Based on the findings, it was shown that plain woven banana fibres demonstrated greater tensile strength (7.39 MPa) and energy absorption (11,772 J) compared to intra-ply woven patterns. The SEM analysis indicated that plain woven fibres had a lower number of surface flaws, highlighting their increased resistance to explosive forces. In conclusion, plain woven banana fibres have significant potential to serve as an alternative to synthetic materials for blast-resistant applications. This alternative is not only cost-effective but also environmentally friendly. Therefore, it is possible for them to meet standards in terms of both environmental sustainability and security.

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

2024-12-02 , Abdul Rashid Othman , Ahmad Humaizi Hilmi , Asna Rasyidah Abdul Hamid , Siti Aisyah Azman

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.
