摘　　要：讨论了四种取代脲促进剂对碳纤维／环氧／双氰胺（ＣＦ／Ｅｐｏｘｙ／Ｄｉｃｙａｎａｍｉｄｅ）体系的弯曲强度、弯曲模量、层间剪切强度的影响，指出了选用Ｍ型促进剂可使复合材料相对于其它三种具有更加优越的干、湿态力学性能，同时该复合材料在饱和吸湿率下８０℃测试时，其层剪强度仍有相当的保持率。This paper tries to analyze the effects of four suburea accelerators on flexural strength,flexural modulus and interlaminar shear strength of carbon fiber reinforced epoxy composite cured by Dicy, and indicates that in dry and wet state, the composite with M type accelerator has much better mechanical properties Meanwhile, the interlaminar shear strength of this composite with saturated water absorption still possesses a relatively high retention when it is tested at 80℃, so the accelerator of M type is recommended as a basic component of mediumtemperature cured epoxy matrix composite with high resistance to hotwet
