The invention provides a winding forming based preparation method of a composite material plate spring body and the plate spring body. The method comprises the steps that fibers penetrate through a solution formed based on a thermosetting resin material or a thermoplastic resin material so as to obtain fibers soaked through the solution; the fibers soaked through the solution are wound in winding space matched with the size of a plate spring in a mold so as to form a preformed plate spring; in the winding process, after at least one layer of fibers is wound every time, a layer of fiber felt is laid on the surface of the at least one layer of fibers, and the two ends of a fiber section in the layer of fiber felt are embedded into the at least one layer of fibers in an arch form through needle heads with barbs; and the preformed plate spring is cured, and 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 time cost and the mold loss cost.

    本申请提供了一种基于缠绕成型的复合材料板簧本体的制备方法及板簧本体,该包括:将纤维丝穿过基于热固性树脂材料或热塑性树脂材料形成的溶液,以获取经该溶液浸渍的纤维丝;在模具中的与板簧的尺寸匹配的缠绕空间内,缠绕经该溶液浸渍的纤维丝,以形成预成型板簧;缠绕过程中,每缠绕至少一层纤维丝后,在该至少一层纤维丝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纤维丝中;对该预成型板簧固化,得到复合材料板簧本体。本申请提供的方法能够在控制时间成本和模具损耗成本的基础上,生产出满足性能要求的板簧。
