The invention provides a preparation method and device of a plate spring body based on winding and HP-RTM and the plate spring body. The method comprises the steps that fiber filaments are wound into fiber rings through a first positioning assembly and a second positioning assembly; the fiber ring carrying the first positioning assembly and the second positioning assembly is laid in a groove of a mold, and a preformed structure is obtained; closing the mold with a cover plate of the mold; then the mold is vacuumized, and a resin material is injected into the groove at a preset pressure; curing the resin material in a pressurizing and heating manner to obtain a to-be-cut structure; and the two ends, comprising the first positioning assembly and the second positioning assembly, in the to-be-cut structure are cut, and the plate spring body is obtained. According to the manufacturing method, the winding technology and the HP-RTM forming technology are combined, and the plate spring body meeting the mechanical property requirement can be produced on the basis of controlling the time cost.
本申请提供了一种基于缠绕和HP‑RTM的板簧本体的制备方法、装置及板簧本体。该方法包括:利用第一定位组件和第二定位组件将纤维丝缠绕成纤维圈;将携带有该第一定位组件和该第二定组件的该纤维圈,铺设在模具的凹槽内,得到预成型结构;利用该模具的盖板封闭该模具;然后对所述模具抽真空并以预设的压力向该凹槽内注入树脂材料;通过加压以及加热的方式固化该树脂材料,以得到待切割结构;切割待切割结构中包括该第一定位组件和该第二定位组件的两端,得到板簧本体。本申请中,将缠绕工艺与HP‑RTM成型工艺相结合,能够在控制时间成本的基础上,生产出满足力学性能要求的板簧本体。
