AFR 700B是一种新型聚合物。它的发明者Tito Serafini是TRW弹道导弹分部的研究人员。在70年代早期,他作为NASA刘易斯研究中心的化学家,就研制出了被广泛使用的高温聚酰亚(石安)——PMR-15。 AFR 700B一经研制出来,很快就被认为是在新近发现的超高温树脂中最有发展前途的。英空军给它取名叫空军树脂(AFR),并且在莱特实验室里为之举办了专题讨论会。在室温下,AFR 700B的强度及刚度与PMR-15一样。当环境温度达到371℃时,它可保持50％的自身性能不变。AFR 700B的热氧化性稳定,其玻璃化温度Tg为399℃。它的化学特性在430℃高温下不发生改变。在生产AFR 700B时不会产生致癌物质,早先的高温树脂如
AFR 700B is a new type of polymer. Its inventor, Tito Serafini, is a researcher at the TRW Ballistic Missile division. In the early 1970s, as a chemist at the NASA Lewis Research Center, he developed the widely used high temperature polyimide (PMMA) - PMR-15. AFR 700B once developed, soon was considered the most promising in the newly discovered ultra-high temperature resin. The British Air Force named it Air Force Resin (AFR) and held a symposium at Wright’s lab. AFR 700B has the same strength and stiffness as PMR-15 at room temperature. When the ambient temperature reaches 371 ℃, it can maintain its own performance of 50% unchanged. AFR 700B is thermally oxidized and has a glass transition temperature Tg of 399 ° C. Its chemical properties at 430 ℃ high temperature does not change. In the production of AFR 700B does not produce carcinogenic substances, such as the previous high temperature resin
