Abstract

The development of different textile structures and their composites for automotive leaf spring applications were considered. Owing to the good mechanical performance of epoxy, it was used as the matrix material in advanced structural applications. Initially, the different textile reinforcement architectures considered were in the form of E-glass unidirectional (UD) tow, bidirectional (2D) plain weave, and 3D woven solid orthogonal and interlock structures. The effect of reinforcing structure on the damping and wear performance of the composites was analyzed for their utilization in automotive leaf springs. Later, four different 3D orthogonal structures were developed to investigate the influence of binder percentage on their damping and wear performance. The damping performance was analyzed in terms of free vibrations, hysteresis damping, and dynamic mechanical properties. A wear analysis was carried out to determine the effect of different reinforcing elements on the friction and specific wear. The 3D reinforced composites considered exhibited the optimum damping and wear behavior.

用于汽车板簧的三维编织增强结构复合材料的阻尼和磨损行为

研究考虑了不同纺织结构及其复合材料在汽车板簧中的应用。由于环氧树脂具有良好的机械性能，因此在先进的结构应用中被用作基体材料。最初考虑的不同纺织加固结构形式包括 E 玻璃单向（UD）丝束、双向（2D）平纹编织以及三维编织实心正交和互锁结构。分析了增强结构对复合材料阻尼和磨损性能的影响，以便将其用于汽车板簧。随后，开发了四种不同的三维正交结构，以研究粘合剂比例对其阻尼和磨损性能的影响。阻尼性能通过自由振动、滞后阻尼和动态机械性能进行分析。此外，还进行了磨损分析，以确定不同增强元素对摩擦和特定磨损的影响。所考虑的三维增强复合材料表现出最佳的阻尼和磨损性能。
