采用正交试验方法分别探讨了阻燃纤维含量、阻燃剂含量、阻燃剂配比、纤维长度对复合材料燃烧性能及力学性能的影响，采用极差分析方法对试验结果进行了分析，找出最佳的配方，然后与其它添加不同种类的阻燃剂的复合材料进行性能比较。结果表明，当纤维长度5mm、阻燃纤维质量为总质量的10%、阻燃剂质量为环氧树脂质量的40%、三聚氰胺焦磷酸盐（MPP）和季戊四醇（PER）配比为3∶1时，复合材料的拉伸强度为20.45MPa，氧指数为33.7，垂直燃烧达到UL94V-O级。燃烧性能和力学性能与环氧树脂相比较，有较为显著的提高，综合性能最好。在纤维长度、阻燃纤维含量、阻燃剂含量都相同的情况下，添加不同种类的阻燃剂，其中添加MPP和季戊四醇的复合材料性能最好。

The orthogonal test was used to study the influence of the content of flame-retarded fiber and fire retardant, the mixture ratio of fire retardant, the length of fiber on flammability and mechanical property of composites. The range analysis was used to analysis the result, the best formula was found. The property of composites was compared with the other composites which were added to the different fire retardant. The result indicated when the length of fiber was 5mm, the quality of flame-retarded fiber was 10% of the total quality, the quality of fire retardant was the quality of epoxy resin 40%, the mixture ratio of melamine pyrophosphate (MPP) and pentaerythritol (PER) was 3∶1, the composites tensile strength was 20.45MPa, the limiting oxygen index (LOI) was 33.7, UL94 rating was reached. Compared to the pure epoxy, combustibility and mechanical property was obviously improved. The total properties were the best as the content of flame-retarded fiber and fire retardant, the length of fiber were the same. Added to the composites with the different fire retardant, the composite properties which added the MPP and PER, were the best.
