我们研究了用于下一代 X 射线卫星的带有碳纤维增强塑料 (CFRP) 基板的轻型 X 射线镜。对于紧密嵌套的 X 射线反射镜,例如朱雀和 ASTRO-H 望远镜上的反射镜,CFRP 是合适的基材材料,因为它比金属具有更高的强度重量比和成形灵活性。在平面 CFRP 基材制造中,表面波纹度具有最佳产品的均方根 (RMS)。 RMS大约达到与用于成形的模具的RMS一致的值。我们在三种环境中使用加速老化测试来研究吸湿性的影响。 CFRP基材在60℃、相对湿度100%的条件下的扩散率为,对实验室环境的加速率高出180倍。我们还在 CFRP 基材上开发了具有低水蒸气透过率的共固化功能片材。与未共固化的基材相比,共固化板材成功地将吸湿率降低了 440 倍。还报告了 CFRP 基材制造和吸湿测试的详细信息。
We study a lightweight x-ray mirror with a carbon fiber reinforced plastic (CFRP) substrate for next-generation x-ray satellites. For tightly nested x-ray mirrors, such as those on the Suzaku and ASTRO-H telescopes, CFRP is the suitable substrate material because it has a higher strength-to-weight ratio and forming flexibility than those of metals. In flat CFRP substrate fabrication, the surface waviness has a root mean square (RMS) ofin the best products. The RMS approximately reaches a value consistent with the RMS of the mold used for the forming. We study the effect of moisture absorption using accelerated aging tests in three environments. The diffusivity of the CFRP substrate at 60°C and at relative humidity of 100% is, and the acceleration rate to the laboratory environment was 180 times higher. We also develop co-curing functional sheets with low water-vapor transmissivity on the CFRP substrate. Co-curing the sheets successfully reduced the moisture absorption rate by 440 times compared to the un-co-cured substrate. Details of the CFRP substrate fabrication and moisture absorption tests are also reported.
