The invention provides a prepreg molding based preparation method of a composite material plate spring body. The method comprises the steps that a prepreg with the same shape as the composite material plate spring body is laid in a mold cavity of a mold, so that a pre-molded plate spring is obtained; in the laying process, when at least one layer of prepreg is laid every time, a layer of fiber felt is laid on the surface of the at least one layer of prepreg, and the two ends of a fiber section in the layer of fiber felt are embedded into the at least one layer of prepreg in an arch form through needle heads with barbs; the mold is closed, and a resin material is injected; and the pre-molded plate spring is cured in a pressurizing and heating manner, so that the composite material plate spring body is obtained. According to the method, the plate spring meeting the performance requirement can be produced on the basis of controlling the equipment research and development cost and the time cost.
本申请提供了一种基于预浸料成型的复合材料板簧本体的制备方法,该包括:将与复合材料板簧本体形状相同的预浸料铺设在模具的模腔内,以得到预成型板簧;铺设过程中,每铺设至少一层预浸料,在该至少一层预浸料的表面铺设一层纤维毡,并通过带有倒钩的针头,以拱形的形式将该一层纤维毡中的纤维段的两端嵌入到该至少一层预浸料中;封闭该模具并注入树脂材料;通过加压以及加热的方式固化该预成型板簧,以得到复合材料板簧本体。本申请提供的方法能够在控制设备研发成本和时间成本的基础上,生产出满足性能要求的板簧。
