Modern national defense is centered around military forces and also includes relevant non military forces; It values the country's war potential, especially the mobilization efficiency during wartime; It is still a comprehensive competition based on economic and technological strength. As one of the most critical fields in the national science and technology development plan, materials technology, along with information technology, biotechnology, and energy technology, is widely recognized as a high-tech that will dominate the overall situation in today's society and for a considerable period of time in the future. High tech materials are still the key modern industrial technologies that support human civilization today. Military new material technology used in the military field is the material basis for developing high-tech weapons and the most important material foundation for a country's national defense.

For the sake of their own interests and the global situation, every country needs and must establish a strong national defense. Therefore, developing modern cutting-edge weapons with independent intellectual property rights is particularly important for national security. However, the current variety, specifications, performance, and smelting process of materials are far from meeting the needs of high-tech weapon development, and sometimes even become a bottleneck restricting weapon research and development. In this context, military material technology has emerged. Currently, there are tens of thousands of military new material technologies worldwide, increasing at a rate of 5% per year, moving towards high functionality, ultra-high energy, composite lightweight, and intelligence.

In the future, next-generation military technologies such as high-power radar jamming systems and hypersonic systems will require extensive data processing, and the processors of these systems will contain many heat generating components. Design engineers must find reliable methods to transfer and dissipate the heat from these components to ensure the continuous and effective operation of the entire system. In commercial applications, thermal management failure may indicate a malfunction of smart devices. But in the military, this could mean mission failure and even serious consequences of loss of life!

The thermal management of these systems is multi-faceted. It includes hardware such as radiators and liquid cooling devices, and also includes thermal conductive silica gel sheets, thermal conductive gel, thermal conductive phase change materials, thermal conductive silicone grease, thermal conductive insulation materials, thermal conductive adhesives, thermal conductive potting adhesives, etc. to transfer the heat of heating elements to the cooling parts. For the military industry, the reliability of thermal conductive materials is crucial!

In order to maximize reliability, thermal interface materials need to possess three characteristics:

A relatively wide range of operating temperatures

The working environment of processors used to control advanced technologies in the military industry is relatively harsh, with severe temperature increases and drops. This temperature cycle may cause damage to the material, requiring it to be able to withstand these temperature fluctuations for a long time.

Durability against harsh environments

Thermal interface materials in military applications may remain near corrosive liquids or vapors, which can corrode the silicone substrate of these materials. Therefore, it is necessary to design a way to protect the interface material and its edges from harmful substances.

Resistance to deterioration

The degassing in thermal conductive materials can hinder the performance of optical lenses, and the military industry has strict requirements for degassing. Post curing process can be used to minimize degassing to the greatest extent possible. Design engineers must closely monitor the raw material formulations in thermal interface materials to better cope with complex military industry product applications.

In order to meet the strict requirements of military products and achieve effective thermal management in new advanced systems, a system level design approach is needed. Many thermal and electromagnetic shielding issues are intertwined nowadays, and considering all possible thermal challenges and electromagnetic interference in the early stages of design can solve them together.
