Abstract

This research aimed to analyze the low-velocity impact on jute/epoxy polymer samples and used their fractured samples for computer tomographic (CT) analysis for predicting the impact damage areas developed on jute/epoxy polymer by using its impact images. The computer tomography analysis was performed with two different thicknesses of natural fabric composites. Initially, this developed the jute/epoxy polymer composites using Compression molding techniques with different thickness and these fabricated samples undergoes to analyzed the low-velocity impact strength with an automated data acquisition system on different thicknesses of jute fabric-reinforced polymer composite materials. The fabricated composite plates were tested under the low-velocity impact testing method with different loading conditions. The higher impact strength was observed on the 6 mm thickness of the plate. The impact analysis on laminate materials is performed with different energy levels on the same thickness of the plate individually. Among various energy absorption tests, the 10 J created more damage on the 3 mm thick plate and 15 J created more damage on the 6 mm thick plate. After the impact testing, the samples were analyzed in the damaged areas using CT scanning systems. Based on this analysis, the fabricated materials were best-suited for lightweight application areas.

界面粘合对黄麻纤维/环氧聚合物复合材料低速冲击性能的影响

本研究旨在分析黄麻/环氧聚合物样品受到的低速冲击，并利用其断裂样品进行计算机断层扫描（CT）分析，通过其冲击图像预测黄麻/环氧聚合物上形成的冲击损伤区域。计算机断层扫描分析使用了两种不同厚度的天然织物复合材料。最初，研究人员利用压缩成型技术开发了不同厚度的黄麻/环氧聚合物复合材料，并利用自动数据采集系统对这些制成的样品进行了低速冲击强度分析，分析了不同厚度的黄麻织物增强聚合物复合材料。在不同的加载条件下，采用低速冲击试验方法对制作的复合材料板进行了测试。在厚度为 6 毫米的板材上观察到了较高的冲击强度。对层压材料的冲击分析是在相同厚度的板材上以不同的能量水平单独进行的。在各种能量吸收测试中，10 焦耳的能量对 3 毫米厚的板材造成的破坏更大，而 15 焦耳的能量对 6 毫米厚的板材造成的破坏更大。冲击测试结束后，使用 CT 扫描系统对样品的受损区域进行了分析。根据分析结果，制造的材料最适合用于轻质应用领域。
