摘　　要：用DSC和FTIR方法研究催化剂二月桂酸二丁基锡(DBTDL)对双酚A氰酸酯及环氧改性氰酸酯体系反应的影响。根据纤维热熔缠绕要求,研制出工艺适用的改性氰酸酯树脂基体。热熔工作温度10 0℃。碳纤维增强复合材料层剪强度测试结果表明,基体适用于纤维热熔法缠绕复合材料。Effects of Dibutyl tin dilaurate（DBTDL） as curing activator on the structure and mechanical properties of bisphenol A dicyanate ester resin（BADCY） and dicyanate - novolac epoxy blends were discussed by means of FTIR and DSC. Dicyanate/novolac epoxy matrix was developed for hot- melt fiber winding process. The melt temperature is 100℃ during the whole prepreg process. ILSS result of carbon fiber reinforced composite shows that the matrix is suitable for hot - melt carbon fiber winding composite material.
