对测定复合材料中水份的非破坏技术的估价[美国]Richard J. Shuford众所周知,水份对增强纤维有机质复合材料的机械性能有不良影响.在饱和状态下典型的含水量在1%至10%范围内,它取决于纤维、基质、应力状态、温度和相对湿度等因素.测定初始材料和复合材料制品中的含水量需要实用的无损检测技术.在实验室中,监控水份吸收所采用的最普遍的方法是定期测量重量 Valuation of Non-Destructive Techniques for Determining Moisture in Composites [USA] Richard J. Shuford It is well-known that moisture adversely affects the mechanical properties of FRP composites. Typical moisture content at saturation is between 1% and 10% Depending on factors such as fiber, matrix, stress state, temperature and relative humidity, the determination of the water content in the starting materials and composite products requires practical non-destructive testing techniques that are used in laboratories to monitor moisture absorption The most common method is to measure the weight regularly
