FAQ

Common questions about carbon fiber EMI shielding

How does carbon fiber provide EMI shielding?

Conductive carbon networks reflect and absorb electromagnetic waves, reducing field strength inside the protected volume when properly grounded and integrated into the enclosure design.

Can recycled carbon fiber meet shielding requirements?

Yes—formulations can be tuned for conductivity and thickness so shielding effectiveness matches typical commercial requirements; we recommend validation against your target frequencies and standards.

Is carbon fiber heavier than metal shielding?

Carbon fiber solutions are often lighter than full metal enclosures while still meeting shielding goals, especially when combined with optimized part design.

Do you support custom grades?

We can work with chopped fiber, mats, and compounds to match resin systems and processing methods for your product line.
