Optical epoxy glue bonding strength test method and device for reflector

Abstract

The invention provides an optical epoxy glue bonding strength test method for a reflector. The values of a dip angle of a variable angle gasket and a bonding angle are controlled to be consistent, thearea of the bonding surface of a test piece and the area of the bonding surface of the reflector are controlled to be consistent, the surface roughness of the bonding surface of the test piece and the roughness of the bonding surface of the reflector are controlled to be consistent, the status of the optical epoxy glue during a true using process is simulated and the bonding strength of the optical epoxy glue is tested. The invention also provides an optical epoxy glue bonding strength test device for the reflector; the device comprises a stretcher, a vertical functional hinge and a horizontal connector. According to the optical epoxy glue bonding strength test method and device for the reflector provided by the invention, the bonding strength under different using conditions can be trulymeasured, and the problems that the design is insufficient or excessive due to the fact that the bonding strength range found from a bonding strength handbook is too wide are effectively solved.

Description

technical field [0001] The invention relates to the technical field of space optical remote sensors, in particular to a method and a device for testing the bonding strength of optical epoxy glue for reflectors. Background technique [0002] Reflector is the most critical optical component in the optical system of space remote sensing camera, and its surface shape accuracy has a direct impact on imaging quality. At present, the support of the reflector of the space optical remote sensor is usually a metal part, and the reflector is made of glass or SiC, and the support of the reflector is fixed by bonding. [0003] Since the space optical remote sensor reflector needs to undergo a series of environmental tests, such as acceleration test, impact test, sinusoidal vibration test, random vibration test, thermal cycle test and vacuum thermal cycle test, etc., the support strength of the reflector is raised. In particular, the bonding strength of the optical epoxy adhesive is a ke...

AI Technical Summary

Problems solved by technology

The bonding strength given by the manufacturer of optical epoxy glue is a general range, and does not take into account the various harsh assessment conditions that space applications will experience, so the bonding strength value cannot be directly used as the design of the bonding support of the reflector Input; and due to objective factors such as different shapes of various space mirrors, bonding size, bonding position and bonding interface, the bonding angle, bonding area and bonding shape are very different
