Abstract

This study investigates the influence of layer configuration on the blast resistance of banana fiber bomb blankets, a sustainable alternative to conventional synthetic protective materials. Twill-woven banana fiber blankets were fabricated with varying numbers of layers ranging from one to five layers, while all other parameters were kept constant to isolate the effect of layer configuration. Controlled explosive blast tests were conducted, and the thermal response of each configuration was measured using Type-K thermocouples connected to a data logging system. The experimental results demonstrate that increasing the number of layers significantly enhances blast mitigation performance by reducing peak temperature transmission and improving energy dissipation across the blanket structure. Among the tested configurations, the five-layer banana bomb blanket exhibited the lowest thermal penetration and superior resistance to blast effects. These findings confirm that optimized multilayer stacking plays a critical role in improving blast resistance by promoting progressive energy attenuation. The five-layer configuration reduced peak temperature transmission from 387.89 °C to 114.80 °C, a 70% reduction, demonstrating superior blast-mitigation performance. The results highlight the potential of banana fiber bomb blankets as an eco-friendly and cost-effective solution for blast protection in industrial and safety-related applications.
