Description

A carbon fiber honeycomb composite panel container with electromagnetic wave shielding Technical Field

[0001] This invention relates to the field of modular housing technology, specifically to modular housing using carbon fiber honeycomb composite panels. Background Technology

[0002] A modular shelter is a containerized workspace that provides a suitable environment and safety protection for personnel and equipment. It features light weight, high load-bearing ratio, good sealing, good heat insulation, and good mobility. In recent years, modular shelters have been widely used in both military and civilian fields.

[0003] In existing technologies, conventional shelters have relatively limited functions, and their structural design primarily focuses on bulletproof safety. Most shelters use steel plates for their walls to provide bulletproof protection, resulting in a limited functionality for the wall panels. This not only makes the equipment inside the shelter susceptible to external electromagnetic interference but also makes it easily detectable by radar. Therefore, this invention proposes a carbon fiber honeycomb composite panel shelter to address these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a carbon fiber honeycomb composite panel cabin to solve the problems mentioned in the background art.

A reflective layer is fixedly connected to the left wall of the left metal plate, and a heat-insulating layer is fixedly connected to the right wall of the right metal plate.

The connecting groove is opened in the metal frame and communicates with the movable groove, and is located on both sides of the movable groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] During installation, the guide groove is aligned with and connected to the rubber pad, while the spring is compressed.
