Abstract

The key objective of this study is to fabricate an unconventional composite structure with outstanding impact performance, low weight, low cost, and better wear resistance. Utilizing a hand lay-up procedure, epoxy composites reinforced with glass fibers (G) and polycarbonate (PC) sheets were fabricated. Neat glass (NG) and three distinct hybrid PC composites were produced by altering the position of the PC sheets. The flat and edgewise impact, in-plane shear strength, and wear behavior of hybrid composites were studied to assess their performance and compatibility for various industrial applications. Morphological investigations of the fractured surfaces were conducted with a digital microscope. The results showed that hybrid PC specimens enhanced flat and edge-wise impact performance by an average of 100.9%. Impact strength values are significantly affected by the arrangement pattern. The presence of PC in the outer and core composite laminates improved shear strength by 15.09% and 14.85%, respectively. The hybrid composites produced smooth and free-of-damage worn surfaces, resulting in a significant reduction in the specific wear rate of 40.4%.

通过加入聚碳酸酯板增强玻璃纤维/环氧树脂复合材料的冲击、剪切和磨损性能
本研究的主要目的是制造一种冲击性能优异、重量轻、成本低、耐磨性更好的非传统复合材料结构。利用手糊工艺,制造出了用玻璃纤维(G)和聚碳酸酯(PC)片增强的环氧树脂复合材料。通过改变聚碳酸酯板的位置,制成了无玻璃(NG)和三种不同的混合聚碳酸酯复合材料。研究了混合复合材料的平面和边缘冲击、平面内剪切强度和磨损行为,以评估它们在各种工业应用中的性能和兼容性。使用数码显微镜对断裂表面进行了形态学研究。结果表明,混合 PC 试样的平面和边缘冲击性能平均提高了 100.9%。冲击强度值受排列模式的影响很大。外层和核心复合材料层压板中的 PC 分别提高了 15.09% 和 14.85% 的剪切强度。混合复合材料产生了光滑、无损伤的磨损表面,使比磨损率大幅降低了 40.4%。
