Applications

In its White Paper European Defense-Readiness 2030, the European Commission urgently pointed out Europe’s inadequate defense readiness. Decades of underinvestment have left the continent poorly prepared for threats, particularly from Russia. A strong and innovative defense industry sector is seen as a prerequisite for peace and security.

An important part of this is the use of new and innovative technology, which is why electronics is one of the core elements that many European companies are currently working on. The function and longevity of the electronics depends on the appropriately designed “thermal management”, especially fast temperature cycles and demanding environmental and operating conditions represent a mechanical and thermal load for electronic assemblies. Kerafol has been actively involved in the development of new products and solutions for this key market for many years. As a result, various Kerafol materials are already an integral part of e.g. drones, current transformers or control units

Areas of application

Defense & Aerospace

Military & Aerospace

The number of electronic applications in the military and aerospace sectors has grown steadily in recent years. Electrification is also progressing here – drones, energy storage systems, control systems and equipment in the field of communication and data transfer have long since ceased to be used only in the industrial sector. Both the military and aerospace follow a similar pattern with regard to the use of electronic assemblies. The reliability of the components installed in them is clearly in the foreground. This requires lengthy and extensive functional and application-related (field) tests by the customer as well as the highest demands on quality and the supplier’s quality-relevant processes.
Anwendungsbeispiel
Thanks to many years of experience in the development of thermally conductive and electrically insulating materials and the highest quality standards in production (e.g. IATF 16949 certification), some products from the KERATHERM® range are already being used successfully here. KERAFOL® is also expanding its portfolio for this industry sector and can therefore offer further innovative solutions to improve performance. With the new KERAMOLD® and KERABSORB® series, thermal conductive materials in any 3D shape or hybrid materials that absorb electromagnetic radiation in addition to their function as gap pads can now also be offered.
Applications in the military and aerospace sectors demand the highest reliability from the components used. We manufacture ceramic substrates for sensors suitable for high temperatures, heat and radiation-resistant plates made of zirconium oxide and aluminum oxide as well as ultra-thin and therefore flexible ceramic components for all applications.

Drones

The market of remotely controlled flying units is growing rapidly. It`s now not only for fun, the role of drones have become more serious among last years. Starting from video and pictures shooting, through support for media market or geodesy and cartography, ending on military usage, these machines are taking leading position in supporting professionals. The development of energy storage systems and miniaturization of electronics made drones lighter and let them work longer on single power load.

Modern drones are equipped with complex battery packs which are not only allowing it to fly long distances or long hours. Variety of instruments, such as cameras, sensors or antennas, need a lot of power to work. These factors increase the demand for energy, parallel the charging of the battery should be done quickly. For those reasons correct thermal management plays an important role. The reliability of electronics and other components can be kept on a high level if the temperature is controlled. Good surface connection of heat source and heat sink can only be achieved if thermal interface materials (TIMs) are used. Next to the heat management, the protection of electronics itself is very important. A Hazardous environment, in which drones are operating, implies variety of circumstances which can lead to the damage of sensitive components. TIMs are perfect in vibration control, electrical insulation, protection against dust and humidity or even sound proofing.

Kerafol offers a wide range of TIMs which are used in drone applications. The KERATHERM® series with Gap Pads and Gap Filler Liquids (GFL) does not only transfer the heat but will also protect components from damage resulting from vibrations. With products from the KERAMOLD® series, PCBs can be overmolded and encapsulated which is an interesting alternative to potting materials or conformal coatings. With that approach, next to the great thermal conductivity, the material offers a soft surface, vibration control, protection against environmental factors and reliability over lifetime. Choice of silicone free materials will be a good response to lighting or sensor applications.

Current transformers and current storage

To ensure that Europe remains independent and resilient, a reliable European supply base is crucial. Cooperation with proven European suppliers – who guarantee quality, reliability and long-term availability – should prevent supply bottlenecks and ensure technological sovereignty.

A key example of the necessary industrial basis are power conversion components (e.g. DC/DC and AC/DC converters). Although often inconspicuous, they are indispensable for the operation of modern military systems such as drones, vehicles or ships. They must meet strict military standards (MIL-STD/MIL-SPEC) in order to function reliably under extreme conditions. Power storage systems in various forms are also increasingly in demand; here, too, the focus is on efficiency and reliability under demanding environmental and operating conditions.

Keratherm® 86/225
KERATHERM® products in particular offer a decisive advantage in terms of protecting the power electronics of electronic assemblies. In addition to classic TIMs (films, gap pads, pastes, etc.), products from the KERAMOLD® series are also increasingly being used. In addition to heat dissipation, this concept also offers protection against dust, moisture or mechanical stress (e.g. vibrations). Kerafol is also developing completely new and customized products specifically for the military sector.

The first product in the new series is the ICE PAD 3000, with an extreme temperature resistance of -90 °C to 200 °C. Conventional materials are only approved up to a maximum of 60 °C and at the -60 °C required by MIL-STD/MIL-SPEC, their softness and elasticity can decrease significantly, which can then lead to a drop in the performance of the electronics. The ICE PAD 3000 retains its basic properties even at -60 °C and is therefore an extremely reliable component for extreme requirements. Further products with this temperature resistance will follow.

KERAFOL® is familiar with the associated application technology and also offers pilot plant trials with dosing systems.
