研究了含磷活性胺在环氧树脂中既可用作交联剂又可用作阻燃剂的适用性，并对其在脂肪族和芳香族环氧树脂体系中的适用性进行了比较。为了满足飞机和航空航天应用对机械性能的强烈要求，碳纤维增强复合材料被制备出来。通过相关试验和质量损失型锥形量热计对其阻燃性能进行了表征。除阻燃性能外，还对其拉伸、弯曲特性和层间剪切强度进行了评价。通过形成由基准复合芯和膨胀性环氧树脂涂层组成的多层复合材料，克服了纤维增强材料的阻胀效应，同时改善了环氧树脂的阻燃性和力学性能。(C) 2010 Elsevier Ltd.版权所有。
The applicability of phosphorus-containing reactive amine, which can be used in epoxy resins both as crosslinking agent and as flame retardant, was compared in an aliphatic and an aromatic epoxy resin system. In order to fulfil the strong requirements on mechanical properties of the aircraft and aerospace applications, where they are mostly supposed to be applied, carbon fibre-reinforced composites were prepared. The flame retardant performance was characterized by relevant tests and mass loss type cone calorimeter. Besides the flame retardancy, the tensile and bending characteristics and interlaminar shear strength were evaluated. The intumescence-hindering effect of the fibre reinforcement was overcome by forming a multilayer composite, consisting of reference composite core and intumescent epoxy resin coating layer, which proved to provide simultaneous amelioration of flame retardancy and mechanical properties of epoxy resins.
