Impact of stacking sequence on vibration damping and viscoelastic behavior of woven jute sustainable composite

Abstract

The potential adoption of sustainable materials as replacements for traditional technological materials, whose production depends on the consumption of non-renewable resources like oil, coal, or natural gas, presents a global issue. Natural resources provide an appealing foundation for reconsidering and, in certain instances, optimising modern manufacturing while also making it sustainable. This study focuses on the impact of the number of layers on the viscoelastic behaviour and vibration damping of a sustainable jute-woven reinforced composite. Five types of samples were prepared using compression moulding technique i.e., Neat Resin (NRC), 2 layer(2WJPC),3 layer(3WJPC), 4 layer(4WJPC) and 5 layers (5WJPC). The findings showed that the 4-layer woven jute-polyester composite has the highest natural frequency (4WJPC) and it is about 40% higher than that of matrix material. The lowest measured damping ratio in the DMA test was found in the 5-layer woven jute polyester composite (5WJPC) at 5 Hz frequency. The woven jute mat composite can be employed as a sustainable damping material for low-cost structures, according to the aforementioned results.
