Resumen
Very few studies have been conducted in the past to reveal the underlying mechanism that causes the high-impact performance of coconuts as a natural composite material and a structure. The goal of this study is to understand the dominant microstructures of coconuts with respect to mechanical impact. In this study, we use a high-resolution X-ray computed tomography (CT) machine in scanning the microstructures and analyzing the patterns of microchannels in coconut shells. By using the established patterns, we model a novel plate structure with coconut-inspired microchannels. Numerical simulation elucidates a significant improvement in crashworthiness. The microchannel design opens a path to further developing self-healing composites and intelligent composites with sensing elements embedded in the channels.
