纤维直径对玻璃纤维直接纱物理性能的影响

Effects of Fiber Diameter on the Physical Properties of Glass Fiber Direct Roving

研究了不同纤维直径对玻璃纤维直接纱的主要物理性能的影响,并通过光学显微镜对玻璃纤维形貌进行研究。结果表明,纤维直径的大小直接影响到玻璃纤维产品的物理性能,且为关键影响因素,其中与纱线断裂强度、毛羽和膨化率呈负相关性,与纱线耐热性和纱线在树脂中的浸透速度呈正相关性。

The effects of fiber diameter on the physical properties of glass fiber direct roving were investigated,and the morphology of glass fiber was studied with optical microscope.The results show that the fiber diameter directly affects the physical properties of glass fiber products and is a key influencing factor.The breaking strength,fuzz and bulking efficiency of roving are negative correlated with the fiber diameter.At the same time,the heat resistance and the wet-out rate of roing in resin are positive correlated with the fiber diameter.
