MODIFIED CYANATE ESTER RESIN MATRIX SUITABLE FOR RTM PROCESS AT AMBIENT TEMPERATURE
-
摘要: 研究了苯基乙烯基化合物(苯乙烯、二乙烯基苯)改性双酚A型氰酸酯(BADCy)树脂体系。通过实验并用三角形图示方法确定了树脂体系的组成和配方,解决了树脂在较低温度下(<40℃)的分相问题,用含杂原子的小分子化合物作为增容剂有效地降低了改性树脂的粘度并增大了贮存稳定性。该树脂适用于室温RTM工艺成型复合材料。Abstract: Phenyl vinyl compounds(styrene and divinyl styrene) modified bisphenol A dicyanate ester resin (BADCy) has been studied in this paper. The composition of the resin matrix has been selected according to a triangular optimization method as well as the experiment result. The phase separation of modified resin matrix at temperatures below 40℃ has been resolved by adding a little molecule substance containing oxygen atoms. At the same time, the storage stability has been prolongated efficiently. The modified resin system is suitable for RTM process at room temperature.
