Assessment of the Impact Performance of Sustainable Three‐Dimensional Woven Jute/Green Epoxy Composites

ABSTRACT Natural fiber reinforced three dimensional (3D) woven composites are an eco‐friendly alternative to synthetic materials supporting sustainable development in automotive, packaging, aerospace and construction sectors. However, 3D interlock patterns' incorporation remains limited to tailor and enhance the impact performance of natural fiber reinforced composites. Addressing the gap, this study explores impact performance of jute/green‐epoxy composites reinforced with 3D interlock (balanced, partially balanced, and imbalanced) interlacements. Impact performance was assessed by charpy, izod, low velocity drop‐weight impact, and split hopkinson pressure bar characterization. Results revealed the significant influence of interlacement patterns variation on impact performance. Imbalanced composite structure exhibited the superior impact response for all characterizations owing to the 5/1 interlocking pattern having a combined effect of high float length and the least crimp percentage. While the balanced composite structure entailed poor impact response having the least value of impact strength and absorbed energy due to the presence of the 2/1 interlocking pattern with the least float length and the highest crimp percentage. Whereas, partially balanced composite structure showed intermediate impact performance. This work presents a baseline for 3D interlacement patterns contributing to the development of sustainable high‐performance composites.
