Abstract

The invention discloses a manufacturing method of a miniature and thin-walled composite ceramic wave-transparent antenna housing. The manufacturing method includes the following steps that: a corresponding braiding core model is designed according to size requirements of a housing body; quartz fiber yarns are adopted as raw materials so as to be attached to and braided on the braiding core model, so that required housing body braided fabric can be obtained; the housing body braided fabric is boiled in water, and then is socked in acid liquid, and finally is socked and composited in a container filled with a silica solution, and therefore, a housing body blank can be obtained; and a bonding part of a connecting ring and the housing body is processed, so that the miniature and thin-walled composite ceramic wave-transparent antenna housing can be obtained. According to the manufacturing method of the invention, mechanical processing is divided into coarse processing and fine processing, and therefore, processing quality of the surface of the housing body can be effectively ensured, and pits on the surface of the housing body are decreased significantly, and at the same time, the uniformity of the materials of the housing body can be improved; after mechanical processing every time, high temperature heat treatment is performed on the housing body blank, and therefore, organic impurities such as oil contamination by which the housing body blank is contaminated in a machining process can be effectively removed, and the performance of a product can be effectively ensured.

Description

technical field

[0001] The invention relates to the technical field of preparation of a wave-transparent radome for missiles, in particular to a method for manufacturing a miniature and thin-walled composite ceramic wave-transparent radome. Background technique

[0002] The radome is located at the head of the missile and is an important structural part of the missile body. It plays the role of load bearing, heat insulation, and wave penetration. It can withstand severe aerodynamic heating and aerodynamic loading in extremely harsh reentry environments. With good wave-transmitting performance, the protection antenna can work normally to ensure strike accuracy.

[0003] Due to the harsh re-entry environment and the temperature as high as 1000°C, traditional resin-based composite materials have been difficult to meet the needs of use. At present, domestic materials that can meet the above requirements and are relatively mature in technology are mainly quartz ceramic materials...
