摘要
针对碳纤维增强氰酸酯复合材料(CFCE)开展原子氧暴露试验及反应产物原位测量的散射试验,并进行暴露前后的质量损失、SEM及XPS试验。结果表明,该材料的受原子氧腐蚀率为(2.20±0.36)×10^(-24)cm^3/atoms。受原子氧腐蚀后,样品表面C元素相对原子浓度增加,O元素基本不变;表面的树脂脱落,碳纤维暴露在原子氧环境中,表面出现蚀坑,且数量及形状逐渐变大,蚀坑相连,最终沿纤维方向形成一条沟壑。高能氧原子与复合材料发生反应,生成产物CO、CO_2、H_2O、OH和CH_3。
Surface properties of carbon fiber/cyanate ester（ CFCE） were investigated after exposure to hyperthermal atomic oxygen. SEM and XPS were used to characterize the chemical and physical changes of the surface of the material. The results indicated that the erosion yield of CFCE is（ 2.20 ± 0.36） × 10^（-24） cm^3/atoms. The relative atomic concentration of C and O,increase and decrease respectively. The surface got rougher with increasing AO fluencies,and as carbon fiber exposed to hyperthermal atomic oxygen,the surface tended to shape cavities,and link ravines finally. The scattering tests show that the productions of CFCE to hyperthermal atomic oxygen are CO、CO_2、H_2O、OH and CH_3.
