Radome and embedded metal ring connection structure and connection method

Abstract

The invention belongs to the field of radome design, and particularly relates to a radome and embedded metal ring connection structure and a connection method, which can ensure root sealing and connection of the radome. The invention provides a connection structure for the radome at the root part and the embedded metal ring and a connection method, so as to solve the problems of radome root sealing and connection in a harsh use environment. During a radome processing process, the embedded metal ring is arranged at the root part of the radome of a composite material, and through the adhesive strength of the composite material itself and a high-temperature and high-pressure forming environment, fixing of structures of the two parts is completed. In order to increase the adhesive strength ofthe two parts, the contact area of the two parts needs to be increased, and a groove and a ridge are designed between the metal connection ring and the composite material radome body contact surface.An adhesive is applied to the contact surface between the composite material radome body and the metal ring to solve the problem of thermal match in the high-temperature forming environment, the sealing performance is good, and the structure and the method can be directly used for guiding design and production.

Description

technical field [0001] The invention belongs to the field of radome design, and in particular relates to a connection structure and a connection method between a radome and a pre-embedded metal ring, which ensure the sealing and connection of the root of the radome. Background technique [0002] In the structural design process of the composite material radome, in order to meet the interface requirements, a metal connection ring is usually designed at the root. There are generally two ways to connect the metal connecting ring and the composite material radome: bonding and screwing. [0003] In the marine environment, the sealing performance is strictly required. At the same time, due to the corrosiveness of the marine environment, adhesives and standard parts for screw joints need to have good corrosion resistance, which puts forward strict requirements on materials. In order to solve this problem, it is necessary to design a new connection method, which not only meets the ...
