摘　　要：采用有机累托石(OREC)改性不饱和聚酯(UP),以改性的UP为基体,以玻璃布为增强材料制备了有机累托石/不饱和聚酯/玻璃纤维三元复合材料(OREC/UP/FIBERS)。通过X射线衍射(XRD)分析了三元复合材料的微观结构,测试了该三元复合材料的力学性能,利用扫描电镜(SEM)、透射电镜(TEM)初步分析了复合材料的增强机理,并研究了三元复合材料的耐湿热性及耐介质性能。结果表明,当OREC添加量为树脂质量分数的2%时,复合材料的综合力学性能较好,且OREC/UP/FIBERS三元体系的耐湿热性及耐碱性较不饱和聚酯/玻璃纤维复合材料的好。A newly developed type of ternary composites was prepared by organic rectorite(OREC)-modified unsaturated polyester(UP) matrix and glass fibre. The micromorphologies and mechanism of OREC-modified composites were investigated by X-ray diffraction(XRD), transmission electron microscopy (TEM) and scanning electron microscopy(SEM). At the same time, the mechanical properties, the damp heat-resistance and the alkali-resistance of the composites were also discussed. It is found that the mechanical properties of composite at 2% OREC loading is the highest among the studied range of OREC loading, and that the damp heat-resistance and the alkali-resistance of the composites containing the OREC are improved when compared with the UP/glass fibre composite.
