通过优化方法减轻智利CFRP镜子生产的透印效应
Mitigating print-through effects through an optimized method for CFRP mirror production in Chile
摘要：
在碳纤维增强聚合物（CFRP）反射镜（从心轴复制）的制造过程中，单向碳纤维层（铺层）的取向对最终产品的不同方面具有直接影响，如其总体（大规模）形状和局部变形。特别是，用于评估表面质量的光学方法可以揭示透印的存在，这是CFPR制造中非常常见的问题。在实践中，除了其他伪影之外，由透印引起的表面的不规则性产生不想要的散射效应，其通常通过将不同材料的额外层施加到表面来减轻。由于CFPR反射镜的主要目标之一是减少整个反射镜系统的最终重量，因此添加更多材料会朝着相反的方向发展。出于这个原因，正在开发一种不同的铺叠方法，其目标是减少印透并提高球度，同时保持机械质量，并且在该过程中不添加额外的材料。
英文摘要：
In the manufacturing process of Carbon Fiber Reinforced Polymer (CFRP) mirrors (replicated from a mandrel) the orientation of the unidirectional carbon fiber layers (layup) has a direct influence on different aspects of the final product, like its general (large scale) shape and local deformations. In particular, optical methods used to evaluate the surface's quality, can reveal the presence of print-through, a very common issue in CFPR manufacture. In practical terms, the surface's irregularities induced, among other artifacts, by print-through, produce unwanted scattering effects, which are usually mitigated applying extra layers of different materials to the surface. Since one of the main goals of CFPR mirrors is to decrease the final weight of the whole mirror system, adding more material goes in the opposite direction of that. For this reason a different layup method is being developed with the goal of decreasing print-through and improving sphericity while maintaining mechanical qualities and without the addition of extra material in the process.
