Abstract

The aim of this research article is to show the effect of Carbon Nanotube (CNT) additive on the performance of composite plate materials with fiber reinforced polymer matrix produced by vacuum infusion method under bending test. In this study, multiple layered composite plates have produced by glass, carbon, and aramid fiber reinforcements with 0.5% CNT addition by mass. In addition, a hybrid composite plate containing glass, carbon and aramid (Kevlar) fiber has produced with CNT addition by using the same production parameters. Three point bending test has performed on the composite plates under 1 mm/min bending with ASTM D7264 standard. As a result, CNT addition has increased the flexural performance but has decreased the elongation of glass and carbon fiber reinforced systems. In aramid reinforced system, both flexural strength and elongation has increased. However, in the hybrid fiber reinforced system, different fiber types have damaged at different elongation distances within the structure under different loads, and gradually more than one failure have observed. When the CNT has added to the hybrid system, the elongation increased but the flexural strength has decreased.

碳纳米管对纤维增强复合材料三点弯曲性能的影响

研究了碳纳米管(CNT)添加剂对真空灌注法制备的纤维增强聚合物基复合材料弯曲性能的影响。在这项研究中，多层复合材料板是由玻璃、碳和芳纶纤维增强，添加0.5%碳纳米管质量。此外，在相同的生产参数下，添加碳纳米管制备了含有玻璃、碳和芳纶(凯夫拉)纤维的混合复合材料板。按照ASTM D7264标准对复合材料板进行了1 mm/min弯曲的三点弯曲试验。因此，碳纳米管的加入增加了抗弯性能，但降低了玻璃和碳纤维增强系统的伸长率。在芳纶增强体系中，抗弯强度和伸长率都有所提高。然而，在混杂纤维增强体系中，在不同荷载作用下，不同类型的纤维在结构内部不同延伸距离处发生破坏，并逐渐出现不止一次破坏。当碳纳米管加入到混合体系中时，伸长率增加，但抗弯强度降低。
