The present study aims at assessing the ballistic impact behaviour of jute reinforced polyethylene glycol (PEG) and nano silica based shear thickening fluid (STF). Preparation of STF is achieved by dispersing the nano silica particles at different weight percentage loadings of 10%, 20%, 30% and 40% in PEG and the effect of various weight percentages loading of nano silica particles on ballistic performance of the proposed composites is studied experimentally. Rheological studies of the prepared STF’s showed that at all nanosilica loading shear thickening occurred and also the shear thickening was highest at higher loading of nano silica at lower rate of shear. The study reveals that the ballistic performance of the jute fabric is enhanced with impregnation of STF. The ballistic results indicate that energy absorption of the proposed composites is enhanced with increased loading of nano silica particles and at the same time, the effect of STF was reduced. Specific energy absorption (SEA) of the neat fabric and the proposed composites was made use of for the purpose of comparing the energy absorption capabilities. It is found that the SEA of proposed composites with 10% nano silica loading is lesser than the neat fabric both in case of 3 layers and 6 layers. It was also found that proposed composite with 40% nano silica loading exhibits highest SEA compared to neat fabric and its counterparts with its SEA being 3.21 and 3.76 times highest compared to three and six layers of neat fabrics respectively.

本研究旨在评估黄麻增强聚乙二醇 (PEG) 和纳米二氧化硅基剪切增稠液 (STF) 的弹道冲击行为。STF 的制备是通过将纳米二氧化硅颗粒以 10%、20%、30% 和 40% 的不同重量百分比负载分散在 PEG 中来实现的，并且纳米二氧化硅颗粒的不同重量百分比负载对所提出的复合材料的防弹性能的影响是进行了实验研究。制备的STF的流变学研究表明，在所有纳米二氧化硅负载下均发生剪切增稠，并且在较低剪切速率下较高负载纳米二氧化硅时剪切增稠最高。研究表明，浸渍 STF 可增强黄麻织物的防弹性能。弹道结果表明，所提出的复合材料的能量吸收随着纳米二氧化硅颗粒负载的增加而增强，同时，STF的影响降低。为了比较能量吸收能力，使用了纯织物和所提出的复合材料的比能量吸收 (SEA)。发现在 3 层和 6 层的情况下，具有 10% 纳米二氧化硅负载的复合材料的 SEA 均小于纯织物。还发现，与纯织物相比，具有 40% 纳米二氧化硅负载的复合材料的 SEA 最高，其 SEA 分别是三层和六层纯织物的 3.21 倍和 3.76 倍。为了比较能量吸收能力，使用了纯织物和所提出的复合材料的比能量吸收 (SEA)。发现在 3 层和 6 层的情况下，具有 10% 纳米二氧化硅负载的复合材料的 SEA 均小于纯织物。还发现，与纯织物相比，具有 40% 纳米二氧化硅负载的复合材料的 SEA 最高，其 SEA 分别是三层和六层纯织物的 3.21 倍和 3.76 倍。为了比较能量吸收能力，使用了纯织物和所提出的复合材料的比能量吸收 (SEA)。发现在 3 层和 6 层的情况下，具有 10% 纳米二氧化硅负载的复合材料的 SEA 均小于纯织物。还发现，与纯织物相比，具有 40% 纳米二氧化硅负载的复合材料的 SEA 最高，其 SEA 分别是三层和六层纯织物的 3.21 倍和 3.76 倍。
