通过地面模拟试验研究了真空紫外辐照对国产BHM3高模量碳纤维质量损失率的影响,并采用扫描电子显微镜(SEM)、原子力显微镜(AFM)和X射线光电子能谱(XPS)仪对辐照前后的样品进行微观分析。结果表明,随着真空紫外辐照剂量增加,碳纤维质损率呈现先增加后平缓现象,质量损失率较少;紫外辐照作用前后碳纤维表面形貌和元素组成基本未变,说明其具有良好的抗紫外辐照性能。
The effects of vacuum ultraviolet radiation on the mass loss rate of domestic high-modulus carbon fiber of BHM3 were studied by ground simulation test. The effects of irradiation on the mass loss of high-carbon fiber of BHM3 were studied. The effects of irradiation on the mass loss of high-carbon fiber were investigated by scanning electron microscope (SEM), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy Before and after the sample for microscopic analysis. The results showed that the mass loss rate of carbon fiber increased firstly and then decreased with the increase of the dose of vacuum ultraviolet irradiation, and the mass loss rate was less. The surface morphology and elemental composition of carbon fiber remained unchanged before and after UV irradiation, indicating that the carbon fiber had good UV radiation resistance.
