汽车零部件轻量化的发展是提高汽车效率的重要课题。通过将聚合物与碳纤维、玻璃纤维和碳纳米管混合，聚合物复合材料已被广泛应用于减轻重量和改善机械性能。在碳纤维增强尼龙6（CF/PA 6）复合材料中加入聚丙烯（PP），以进一步实现复合材料的轻量化和耐水性。然而，PP的加入降低了力学性能。在这项研究中，添加了多壁碳纳米管（CNT）来补偿添加PP时机械性能的降低。进行拉伸试验和弯曲试验以评估机械性能。少量CNTs的加入提高了碳纤维增强PA 6/PP复合材料的力学性能。加入30wt%PP后，CF/PA 6的密度从1.214降低到1.131 g/cm 3（6.8%）;加入0.5wt%CNTs后，CF/PA 6复合材料的拉伸强度从168 MPa提高到173 MPa（3.0%），但密度略有增加（1.135 g/cm 3）。所开发的复合材料将广泛用于轻质汽车部件，具有更好的机械性能。
The development of lightweight automotive parts is an important issue for improving the efficiency of vehicles. Polymer composites have been widely applied to reduce weight and improve mechanical properties by mixing polymers with carbon fibers, glass fibers, and carbon nanotubes. Polypropylene (PP) has been added to carbon fiber-reinforced nylon-6 (CF/PA6) composite to achieve further weight reduction and water resistance. However, the mechanical properties were reduced by the addition of PP. In this research, multiwalled carbon nanotubes (CNTs) were added to compensate for the reduced mechanical properties experienced when adding PP. Tensile testing and bending tests were carried out to evaluate the mechanical properties. A small amount of CNTs improved the mechanical properties of carbon fiber-reinforced PA6/PP composites. For example, the density of CF/PA6 was reduced from 1.214 to 1.131 g/cm3 (6.8%) by adding 30 wt % PP, and the tensile strength of 30 wt % PP composite was improved from 168 to 173 MPa (3.0%) by adding 0.5 wt % CNTs with small increase of density (1.135 g/cm3). The developed composite will be widely used for lightweight automotive parts with improved mechanical properties.
