Abstract

The invention belongs to the technical field of electronic materials, and in particular relates to a slotted honeycomb wave-absorbing structure. The present invention provides space for embedding electronic modules such as antennas and radars inside the honeycomb structure by opening n identical irregular gaps in the periodic honeycomb structure, and realizes the design method based on the pre-embedding of the honeycomb wave-absorbing structure, that is, the honeycomb core is partially Hollowing treatment, embedding highly integrated electronic modules inside the core and carrying out protection design, has made a qualitative leap in the design of spacecraft in terms of lightweight and multi-function. The key issue of pre-embedded design is to evaluate the electromagnetic / mechanical strength of the honeycomb structure after slits, so that it can not only reduce the weight of the honeycomb structure, but also have good electromagnetic / mechanical properties under a reasonable slit method.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, in particular to a slotted honeycomb wave-absorbing structure. Background technique [0002] The honeycomb absorbing structure has the characteristics of light weight, high specific strength, excellent impact resistance and ability to absorb electromagnetic waves. Widely used in aerospace, transportation and other fields. Among them, reducing the mass of spacecraft is one of the important goals of modern aerospace technology. Specifically, it is to reduce the quality of spacecraft by an order of magnitude on the existing basis, so that my country's aerospace technology has made significant progress. [0003] The purpose of multifunctional structural technology is to "perfectly combine" passive electronic components with composite materials to integrate functions such as thermal function, electronic function and radiation shielding effectiveness into the inherent load-bearing parts o...
