| 目的 研究使用新方法制造小型大曲率glare板零件的可能性。方法 通过使用传统的模具来充液成形/普通拉深成形含有半固化玻璃纤维预浸料的glare板，成形后再进行固化。在室温下，使用单向拉伸方法分别对金属、含半固化玻璃纤维预浸料的glare板和固化之后的glare板进行力学性能测试。结果 含半固化玻璃纤维预浸料的glare板主要失效形式为金属板断裂，固化之后的glare板的主要失效形式为玻璃纤维断裂；含半固化玻璃纤维预浸料的glare板有着和金属相近的断后伸长率，具有较好的塑性，固化之后的glare板的断后伸长率远小于金属的断后伸长率，塑性极差。结论 通过使用传统的模具来充液成形/普通拉深成形含有半固化玻璃纤维预浸料的glare板，成形后再固化的方法来制造小型大曲率glare板零件是有可能的。 |
| 英文摘要: |
| The paper aims to research the possibility of manufacturing small curvature glare plate parts with new method. Traditional molds are used for hydroforming/general drawing to form glare plates with semi-cured glass fiber prepreg to cure them after forming. Mechanical testings of glare plate with semi-cured glass fiber prepreg and glare plate were carried out at room temperature through uniaxial tension. Results show that glare plate containing semi-cured glass fiber prepreg mainly failed in fracture of metal plate. The main failure form of glare plate after curing was fracture of glass fiber; glare plate containing a semi-cured glass fiber prepreg had a similar elongation with metal, and had good plasticity. The elongation after fracture of glare plate after curing was far less than the elongation of metal. It is possible to have hydroforming/general drawing to form plate containing glare semi-cured glass fiber prepreg with traditional mold to manufacture small curvature glare plate parts after forming and curing. |
