Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0029] In order to solve the problems of high difficulty and high cost in the existing method for preparing large-diameter composite mirrors, the present invention divides the large molds for preparing large-diameter composite mirrors into parts, and manufactures composite molds of multiple monomers. Assembled into a large mold, the purpose of doing this is firstly that the composite material of the monomer is small and easy to prepare, which can greatly reduce the difficulty of preparing a large mold; The preparation cost of the large-aperture composite mirror is reduced.

Abstract
The invention discloses a method for preparing a large-diameter composite material reflecting mirror. First, the size, shape and quantity of the basic unit are determined according to the diameter and curvature of the large-diameter composite material reflecting mirror to be prepared; The shape is processed into a unit mold with twice the number of the basic unit; then, according to the basic unit mold, a vacuum bag preparation process, RTM process or a compression molding process is used to prepare a carbon fiber composite mold with twice the number of the basic unit; The carbon fiber composite material mold is prepared into two large-diameter composite material mirror molds, and finally, the two large-diameter composite material mirror molds are prepared into large-diameter composite material mirror mirror blanks by vacuum bag technology; The surface of the mirror blank is coated to prepare a large-diameter composite material reflector. The invention can reduce the manufacturing cost and difficulty of the large-diameter composite material reflecting mirror.
Description
technical field [0001] The invention relates to the technical field of optical element preparation, in particular to a method for preparing a large-diameter composite mirror. Background technique [0002] With the continuous development of science and technology, in order to achieve the goal of seeing farther and clearer, optical observation equipment tends to be larger in diameter, and the lack of manufacturing capacity of large-diameter mirrors is one of the main factors restricting the performance improvement of optical observation equipment. How to manufacture large-aperture mirrors quickly and at low cost has become an urgent problem to be solved. The existing single mirrors have a limited caliber and high manufacturing cost. Another method of manufacturing large-diameter mirrors by splicing is also limited by the weight of materials or the assembly and adjustment of sub-unit mirrors to synthesize large-diameter mirrors. the complexity. [0003] With the continuous ad...
