The invention discloses a hollow structure composite material control arm and a preparation method thereof.The control arm comprises a control arm body, a front lining, a rear lining and a ball head, the front lining, the rear lining and the ball head are arranged at the corner of the control arm body, the control arm body is a hollow body, and the front lining and the rear lining are arranged in the control arm body through structural adhesive films. According to the hollow structure composite material control arm and the preparation method thereof, the design is reasonable, the integrated hollow structure is adopted, PMI foam does not need to be filled in a solid structure, and thermoplastic scheme secondary curing or structural adhesive bonding after two halves are not needed either; the control arm of the hollow structure can improve the weight reduction ratio, meanwhile, the thermosetting continuous fiber composite material can better mold the hollow structure with better performance at a time in the process, manufacturing is easy and convenient, and cost is relatively low.
本发明公开了一种空心结构复合材料控制臂及其制备方法,其控制臂包括控制臂本体以及设在控制臂本体拐角处的前衬套、后衬套以及球头,所述控制臂本体为中空本体,所述前衬套和后衬套均通过结构胶膜设在控制臂本体中。该空心结构复合材料控制臂及其制备方法设计合理,采用一体式空心结构不需要实体结构填充PMI泡沫,也不需要热塑性方案二次固化或两半式后使用结构胶粘接;其空心结构的控制臂可以提高减重比,同时热固性连续纤维复合材料在工艺上也能更好一次性成型出性能更好的空心结构,制作简便,成本相对较低。
