The present investigation focuses on the design and development of low-cost carbon and glass fiber-reinforced polymer hybrid composite with optimum flexural strength and modulus, Charpy impact strength, resistance to low-velocity impact, and abrasive wear. There are three hybrid composites ([C2G8], [C3G7], and [C4G6]) along with a plain glass ([G10]) and carbon ([C10]) fiber-reinforced polymer composites are fabricated using hand lay-up method. The results revealed that [C2G8] type hybrid composite possessed optimum flexural strength (394.35 MPa), resistance to low-velocity impact (92.42 J), Charpy impact strength (160 kJ/m2), and minimum specific wear rate (22.87 × 10–3 mm3/Nm) in comparison to other hybrid composites. The damaged area due to low- velocity impact was found to be least for [C2G8] type hybrid composite compared to other hybrid composites. Furthermore, fractography analysis was carried out by visual inspection and scanning electron microscopy to make possible structure–property co-relationship.

碳/玻璃纤维增​​强聚合物杂化复合材料低速冲击和耐磨性的改进

目前的研究重点是设计和开发具有最佳弯曲强度和模量、夏比冲击强度、抗低速冲击和磨料磨损的低成本碳和玻璃纤维增​​强聚合物混合复合材料。共有三种混合复合材料([C 2 G 8 ]、[C 3 G 7 ] 和 [C 4 G 6 ])以及一种普通玻璃([G 10 ])和碳([C 10 ])纤维增强材料聚合物复合材料采用手糊法制造。结果表明,[C 2 G 8] 型混合复合材料具有最佳弯曲强度 (394.35 MPa)、抗低速冲击 (92.42 J)、夏比冲击强度 (160 kJ/m 2 ) 和最小比磨损率 (22.87 × 10 –3 mm 3 /Nm ) 与其他混合复合材料相比。发现与其他混合复合材料相比,[C 2 G 8 ] 型混合复合材料由于低速冲击造成的损坏面积最小。此外,通过目视检查和扫描电子显微镜进行断口分析,使结构-性能的相互关系成为可能。
