Abstract:

建立了单丝断裂双树脂体系法,利用外层树脂的韧性使包埋于内层脆性树脂中的纤维单丝断裂达到饱和,解决了断裂伸长率较低的树脂基体采用传统的单丝断裂法无法测得界面剪切强度的问题。分别采用界面剪切强度和界面断裂能作为表征参量,考察了干态及湿热条件下两种T300级和两种T800级碳纤维/环氧树脂的界面性能,并与单丝断裂单树脂体系的界面性能进行比较。结果表明:单丝断裂双树脂体系与单树脂体系在表征碳纤维/环氧树脂的界面性能上定性规律一致;双树脂体系界面断裂能和界面剪切强度均可评价界面的耐湿热性能,且二者得到的变化规律一致;湿热处理后界面粘结性能均呈下降趋势,国外碳纤维体系的界面耐湿热性能明显优于国产碳纤维体系。
