中文摘要:合成一种无卤阻燃环氧树脂,并采用热熔法预浸工艺制备出玻璃纤维织物增强环氧树脂预浸料。通过DSC、流变仪等手段对树脂性能进行表征分析。将树脂与玻璃纤维织物进行复合制备预浸料并通过热压罐成型工艺制备复合材料,对复合材料的力学性能和阻燃性能进行表征分析。结果表明:该无卤阻燃环氧树脂及预浸料具有良好的工艺加工性,用其制备的复合材料试验件具有良好的力学性能和阻燃性能,垂直燃烧/水平燃烧、热释放速率、烟密度、烟毒性各项性能均可满足CCAR等适航标准的要求。
英文摘要:A halogen-free flame retardant epoxy resin was synthesized, and glass fiber fabric reinforced epoxy resin prepreg was prepared by hot melt process. The properties of resin were characterized and analyzed by means of DSC and rheometer. The prepreg was prepared by epoxy resin and glass fiber fabric; composite material was prepared by autoclave forming process and the mechanical properties and flame retardant properties of the composite were analyzed. The results show that the flame retardant epoxy resin and prepreg have good processability; the composite have good mechanical properties and flame retardant properties; and all the properties of vertical/horizontal combustion, heat release rate, smoke density and smoke toxicity could meet the requirements of CCAR and other airworthiness standards.
