摘要:
分析了作为复合材料增强体使用的天然亚麻植物纤维的动态润湿过程，观测了植物纤维及其预浸渍纤维纱线表面形貌，探讨植物纤维与不同液体体系（去离子水，环氧树脂）的润湿特征，并与使用广泛的玻璃纤维动态润湿过程进行比较。基于Wilhelmy法，通过在极低速率下建立纤维与树脂动态润湿系统及浸润力学模型，结合流场函数和表面轮廓中线平均算术偏差粗糙度理论方法，运用方差分析技术提出了定量判断增强体纤维表面固有粗糙水平的新方法。分析探讨了亚麻植物纤维和玻璃纤维与浸润液体的粘附功。结果表明：作为复合材料增强体，亚麻植物纤维表面粗糙因子更大，亚麻植物纤维动态润湿过程润湿力、粘附功较小，同等条件下，相比玻璃纤维具有较差的润湿性能。
Abstract:
In this paper, the dynamic wetting process of natural flax plant fiber used as composite reinforcement is analyzed, the surface morphology of plant fiber and its preimpregnated fiber yarn is observed. The wetting characteristics of plant fiber with different liquid systems (DI water, epoxy resin) are discussed, and compared with the dynamic wetting process of widely used glass fiber. Based on Wilhelmy method, a new quantitative judgment method to identify the inherent roughness level of fiber reinforcement surface is proposed by establishing the dynamic wetting system and wetting mechanic model of fiber and resin at very low rate, combined with the stream function and the roughness theory of arithmetical mean deviation of the surface profile midline, and using the variance analysis technology. The adhesion work of flax plant fiber and glass fiber with wetting liquids was analyzed and discussed. The results show that, as composite reinforcements, the surface roughness factor of flax plant fiber is bigger and the wetting force/adhesion work of flax plant fiber in the dynamic wetting process are smaller. At the same condition, flax plant fiber has poor wetting performance compared with glass fiber.
