| 中文摘要: |
| 针对碳纤维光学元件复制过程中的纤维印透现象，提出了镍-环氧树脂-镍的缓冲层方法。以单向碳纤维材料为基底，采用传统方法制备了碳纤维-环氧树脂-银膜结构的光学反射镜；采用缓冲层方法，制备了碳纤维-镍-环氧树脂-镍-银膜的光学反射镜。用台阶仪测试了这两种光学元件在垂直纤维方向和沿纤维方向的表面形貌。结果表明，纤维印透现象主要发生在垂直于纤维方向，在小尺度范围内，缓冲层构对纤维印透现象有明显的抑制作用，碳纤维复制表面粗糙度振幅低于50nm；在大范围内复制表面仍存在突变，但好于采用传统方法制备的没有缓冲层的反射镜。 |

| The method of interlayer alleviation to mitigate fiber print-through phenomenon in Carbon Fiber Reinforced Polymer (CFRP) mirror replication process was presented. Using traditional method and interlayer method in CFRP replication technique respectively, two mirror samples have been fabricated and measured by step tester along and perpendicular to the fiber direction. The results show the fiber print-through phenomenon is available perpendicular to the fiber direction. In small range area, the alleviation layer obviously mitigates the print-through phenomenon with the surface roughness less than 50nm. Although the surface error exists in large range area, it is still better than that by traditional methods. |
