一种碳纤维/环氧树脂预浸料的热压罐成型方法
摘要：
本发明属于碳纤维复合材料技术领域，具体为一种碳纤维/环氧树脂预浸料的热压罐成型方法。本发明方法包括如下步骤：模具涂覆脱模剂，预浸料铺层，模具放入真空袋，装入真空袋的模具放入热压罐，检查真空袋气密性，预浸料固化成型。其所述预浸料固化成型包括下述步骤：(1)在压力为0，温度为75～85℃下，预固化30～45min；(2)在压力为0.3～0.5MPa，温度为120～130℃下，固化120min。本发明提供的热压罐成型方法具有压力、温度均匀的特点，所制备的层合板力学性能优良，尺寸稳定性好。
摘要（英）：

The invention belongs to the technical field of a carbon-fiber composite material, and concretely relates to a carbon fiber/epoxy resin prepreg autoclave molding method. The method comprises the following steps: coating a mold with a release agent, laying the prepreg, placing the mold in a vacuum bag, placing the vacuum bag filled with the mold in an autoclave, inspecting air impermeability of the vacuum bag, and performing curing molding on the prepreg. The prepreg curing molding step comprises the following processes: 1) under conditions that pressure is 0 and temperature is 75-85 DEG C, precuring the prepreg for 30-45 minutes; and 2) under conditions that pressure is 0.3-0.5 MPa and temperature is 120-130 DEG C, curing the prepreg for 120 minutes. The autoclave molding method has the characteristics of uniform pressure and temperature, and a prepared lamination plate has the advantages of excellent mechanical property and good size stability.
