【摘要】 采用溶胶-凝胶技术制备有机/无机纳米杂化涂层材料,通过红外光谱和原子力显微镜技术对该材料进行表征分析,结果表明合成了环氧/SiO2纳米杂化材料。采用合成的纳米杂化浆料对玄武岩纤维进行表面改性,通过纤维表面形貌、纤维复丝拉伸强度和复合材料层间剪切强度分析,研究玄武岩纤维表面涂层改性效果。试验结果表明:采用适当浓度的涂层溶液对玄武岩纤维进行表面改性可以有效的增加纤维表面粗糙度,提高纤维复丝拉伸强度,改善复合材料界面粘接强度,说明玄武岩纤维表面涂敷有机/无机纳米杂化涂层的改性方法是确实有效的。更多还原

【Abstract】 The organic/inorganic hybrid sizing was synthesized by sol-gel method.The IR and AFM analysis results indicated that the epoxy/SiO2 nano-hybrid material was synthesized.The basalt fibers were surface modified by organic/inorganic nano-hybrid sizing.The surface morphology of basalt fibers,the multifilament yarn tensile strength and the ILSS of its composites were investigated.The results indicated that when the basalt fibers were modified by hybrid sizing with optimum concentration the surface morphology of the fiber was rougher and the tensile strength was increased,meanwhile the ILSS of its composites was improved.All of these research proved that the sizing modification using organic/inorganic nano-hybrid sizing was an effective method for improving basalt fiber and its composites properties.更多还原
