Abstract

The invention relates to a manufacturing method for a satellite borne antenna reflecting surface, particularly relates to a manufacturing method for a high-precision satellite borne antenna reflecting surface adopting a carbon fiber composite panel aluminium honeycomb sandwich structure, and belongs to the technical field of satellite communication and deep space detection. The reflecting surface is shaped like a 'cap with a brim', the periphery of a panel adopts a symmetrical laying layer, and is enabled to form a local thickened symmetrical laying layer, the maintenance of the shape surface precision during the panel forming process and the follow-up operation is facilitated, and the condition that the inboard shrinkage produced due to the differential pressure change during the honeycomb sandwich structure forming process influences the precision of the center reflecting area is prevented.

Description

technical field

[0001] The invention relates to a method for preparing a reflective surface of a space-borne antenna, in particular to a method for manufacturing a reflective surface of a high-precision space-borne antenna with a carbon fiber composite panel aluminum honeycomb sandwich structure, belonging to the technical fields of satellite communication and deep space detection. Background technique

[0002] Antennas are important payloads of spacecraft. Carbon fiber composite materials have the characteristics of high specific strength, high specific modulus, low thermal expansion coefficient, etc., and are ideal materials for making high-precision antennas. The honeycomb sandwich structure is widely used in the field of antennas due to its high overall stiffness. However, with the rapid development of communication and detection technology and the increase of satellite life in orbit, higher requirements are put forward for the environmental test conditions of the anten...
