NPF的CFRP反射镜制造过程的质量控制
Quality control of the CFRP mirror manufacturing process at NPF
摘要:
理想情况下,复制CFRP反射镜的表面质量应与制造它们的心轴一样好。在实践中,许多因素在不同尺度下在最终反射镜中产生表面缺陷。为了了解这些误差的来源,并相应地改进制造工艺,必须采用广泛的计量技术和质量控制方法。采用机械和光学仪器在不同的空间频率范围内对玻璃芯轴和CFRP复制品进行了扫描。模态分析用于识别大尺度像差,并辅以中小尺度的光谱分析。可以看出,散光是CFRP复制品中的主要像差。在中等和小规模,我们已经观察到,纤维打印通过和表面粗糙度可以显着改善的复制品的表面上的额外的树脂层,但仍然存在一些残余的不规则性。
英文摘要:
The surface quality of replicated CFRP mirrors is ideally expected to be as good as the mandrel from which they are manufactured. In practice, a number of factors produce surface imperfections in the final mirrors at different scales. To understand where this errors come from, and develop improvements to the manufacturing process accordingly, a wide range of metrology techniques and quality control methods must be adopted. Mechanical and optical instruments are employed to characterise glass mandrels and CFRP replicas at different spatial frequency ranges. Modal analysis is used to identify large scale aberrations, complemented with a spectral analysis at medium and small scales. It is seen that astigmatism is the dominant aberration in the CFRP replicas. On the medium and small scales, we have observed that fiber print-through and surface roughness can be improved significantly by an extra resin layer over the replica's surface, but still some residual irregularities are present.
