The invention provides a high-performance large-size carbon fiber light shield, a preparation method and a preparation mold thereof, and belongs to the technical field of composite materials. The problems that the front light shield is large in structural mass and complex in forming process are solved. Grid ribs of the light shield are prepared and formed by adopting a split mold matching forming process and a prepreg laying forming process, and after split molds on which all prepreg laying is completed are assembled together, a skin is integrally formed by adopting prepreg. The light shield is large in size, simple in forming process and suitable for protecting optical systems such as a camera and a telescope of a spacecraft and preventing the camera and the telescope of the spacecraft from being damaged by solar radiation in a space environment.

    本发明提出了一种高性能大尺寸碳纤维遮光罩、制备方法及其制备模具,属于复合材料技术领域。解决了此前遮光罩结构质量大、成型工艺复杂的问题。该遮光罩的网格筋采用分瓣模具对模成型工艺和预浸料铺放成型工艺制备成型将所有预浸料铺发完成的分瓣模具组装在一起后,采用预浸料一体化成型蒙皮。该遮光罩遮光罩尺寸大、成型工艺简单,适用于对航天器的相机、望远镜等光学系统的保护,以防航天器相机、望远镜等在空间环境中受太阳辐射而损坏。
