HIGHLIGHTS
- The carbon fiber structure causes additional signal interference.
- A carbon fiber casing does not provide good protection against the effects of LEMP.
- The signal inside the housing for low frequencies is amplified.
- The impact signal passing through the carbon fiber undergoes significant dispersion.

ABSTRACT
The Aim of the study was to determine the effect of a carbon fiber enclosure on overvoltages induced in unmanned aerial vehicle (UAV) circuits. Carbon fiber reinforced polymer (CFRP) is characterized by a heterogeneous structure and a thorough analysis of its impact on the LEMP (Lightning ElectroMagnetic Pulse) protection of UAVs is crucial for the further development of such machines. The shorter the distance, the greater the amplitude of the EMP, the greater the value of the surges. Their maximum value determines the safe zone. This distance can be reduced by using an enclosure that can absorb or dissipate EMP. The tested object was placed between a large capacitor plates, which ensured the uniformity of the field. This article presents new results of tests on the CFRP shielding effectiveness against the electrical component of atmospheric discharge. Using described below method, an increase in the signal amplitude inside the box was achieved in relation to the input signal, thus strengthening it instead of suppressing it.
