QY8911双马来酰亚胺树脂——一种符合世界技术发展潮流的耐热树脂新品种,经北京航空工艺研究所两年多的研究试验,最近取得成功。其综合性能达到国外80年代初中期水平,从而使我国的双马树脂研究跻于世界中等水平行列。 北京航空工艺研究所于60年代后期率先在国内开展碳纤维复合材料研究,曾从筛选过的多个树脂配方中,选择了环氧648/三氟化硼单乙胺体系。由于其工艺性良好,常温下自然存放期较长,有可控的高粘度,因此,在许多结构上得到应用。然而,由于它对湿热综合作用下的敏感度高,其应用范围受到了限制。
QY8911 Bismaleimide Resin - A new heat-resistant resin that meets the world trend of technological development. It has recently been successfully tested by the Beijing Institute of Aeronautical Technology for more than two years. Its comprehensive performance has reached the level of the early and mid-1980s in foreign countries, so that China’s bismaleimide resin research ranks among the middle ranks in the world. Beijing Institute of Aeronautics and Astronautics pioneered the research on carbon fiber composites in China in the late 1960s. The epoxy 648 / boron trifluoride monoethylamine system was selected from a number of selected resin formulations. Because of its good workmanship, the natural storage at room temperature longer, with controlled high viscosity, therefore, has been applied in many structures. However, due to its sensitivity to combined heat and humidity, its range of applications is limited.
