Abstract
The invention discloses a full carbon fiber composite material reflection lens for an optical system and a manufacturing method. A carbon fiber composite material is used for manufacturing each component of the reflection lens, and the full carbon fiber composite material reflection lens is obtained by adhesively-bonded cocuring. The anti-deformation performance is strong, the thermal stability is good, and the temperature matching problem of the reflection lens and camera other composite material structures is solved. According to the manufacturing technology, the high precision full carbon fiber composite material reflection lens can be manufactured in a short time, and compared with a conventional reflection lens manufacturing process, the technology has the advantages of short manufacturing cycle and low manufacturing cost.
Description
technical field [0001] The invention relates to an all-carbon fiber composite reflector for an optical system and a manufacturing method thereof, belonging to the technical field of advanced composite materials. Background technique [0002] Remote sensing is the main means to achieve real-time and all-weather detection of military targets. The level of remote sensing cameras determines the modernization level of a country's national defense. Therefore, since the 1980s, remote sensing cameras have been competing for development among the world's major powers. The most representative It is the IKNOS, SPOT5, KH series and other cameras in the United States, and its resolution has reached the level of 0.2 meters. With the development of remote sensing observation technology, the resolution required for earth observation and space exploration is getting higher and higher, and the corresponding optical aperture is also getting larger. Large-aperture, high-resolution mirrors have...
