摘要
通过红外分析,发现硼酚醛树脂中的硼元素以化学键形式存在于分子链中。热失重结果表明,硼酚醛树脂的初始分解温度为220℃,在800℃时残碳率为65.5%。硼酚醛树脂的复合材料在250℃力学性能保持率为70%左右,可作为一种耐高温结构材料使用。
Through infrared analysis, it can be found that the boron exists in the molecular chain as chemical bonds in the boron phenolic resin. Thermal gravimetric analysis resuh shows the initial decomposition temperature of this boron phenolic resin is 220℃ ,the residual carbon rate at 800℃ is about 65 percent. The maintain rate of boron phenolic resin composite material on its mechanical properties at 250℃ is about 70 percent, so it can be used as a high temperature structural material.
