Military and commercial vehicles operate in varied electromagnetic (EM) environments, which affect their onboard electrical/electronic systems. Lightning, electromagnetic pulse (EMP), and high-power microwave energy can cause detrimental effects.
Although circuit architecture is used to mitigate some of these effects, a sure way is to place the sensitive electronics within a “Faraday cage.” Traditional methods rely on thick metallic structures for these Faraday cages, which collectively occupy significant weight in a vehicle and directly impact performance and payload capability. In many instances, the parasitic weight is traded for performance and can lead to the reduction and/or elimination of certain levels of EM shielding.
Composite materials provide a lighter-weight option for EM shielding.
This webinar will cover the following topics:
- What are the potential EM threats?
- How are electronics and electrical systems currently shielded from EM exposure?
- What types of EM shielding in composites are possible?
- Multifunctional materials.
- Manufacturing and fabrication concerns.
- Repairability and maintainability aspects.
- Future direction.
