【摘要】：采用旋转式流变仪表征腰果壳油改性的酚醛树脂共混体系在不同温度下的静态流变性能,同时基于碳纤维/铜纤维深交联机织物的结构特性设计出针对复合材料的热压及固化温度;通过改变固化过程中的升温速率,探究最佳的复合材料热压-固化工艺。通过对复合材料进行截面能谱扫描(EDS)和固化后的孔隙率测试来对不同固化工艺进行比较。结果表明,通过模具将树脂基体胶液浸渍碳纤维/铜纤维深交联织物并进行热压的方法来实现预制体与树脂的复合,且固化升温速度为10℃/h时可以获得具有较低孔隙率的复合材料且树脂体系中的填料能够更均匀的分布在复合材料中。
[Abstract]:The static rheological properties of the phenolic resin blend system modified by cashew nut shell oil with rotary rheometer at different temperatures were studied. At the same time, based on the structural characteristics of carbon fiber / copper fiber deep intersecting on-line fabric, the hot pressing and curing temperature of composites are designed, and the optimum hot-pressure-curing process of composites is explored by changing the heating rate during the curing process. Different curing processes were compared by (EDS) and porosity measurement after curing. The results show that the composite of preform and resin can be realized by impregnating carbon fiber / copper fiber deep crosslinking fabric by mould. The composites with low porosity can be obtained at the curing rate of 10 鈩，
