摘　　要：利用等离子烧蚀试验系统,对纤维增强酚醛树脂复合材料进行烧蚀试验,并对不同复合材料的烧蚀率和微观形貌进行测试和分析。等离子烧蚀试验条件为:功率60kW,热流密度25000kW/m^2,烧蚀时间8s。结果表明:碳纤维、高硅氧纤维、玻璃纤维增强酚醛树脂复合材料的等离子线烧蚀率分别为:0.180mm/s、0.666mm/s、0.613mm/s,质量烧蚀率分别为:0.167g/s、0.310g/s、0.338g/s,线烧蚀率和质量烧蚀率相对偏差都在5%以内。利用扫描电子显微镜和X射线能谱仪对烧蚀样品的微观形貌进行分析,对不同纤维增强酚醛树脂基复合材料的等离子烧蚀机理进行了探讨。Ablation tests for phenolic resin based composites were performed by using plasma arc system.The ablation rates of the composite materials were measured individually during each test.The condition of the plasma arc ablation test was fixed the same for all tests,which was power of 60 kW,heat flux density of 25000kW/m^2 and ablation time of 8s.Under this condition,the linear ablation rates of the carbon fiber,high silica fiber and glass fiber reinforced phenol-formaldehyde resins were 0.180mm/s、0.666mm/s and0.613mm/s,while the mass ablation rates were 0.167g/s、0.310g/s and 0.338g/s,respectively.The relative standard deviations were all less than 5%.Ablation mechanism of the composite materials was discussed based on the microscopic morphology obtained by SEM and EDS.
