Lightning Impulse Current Tests on some Electroconductive Fabrics

On the search of lightweight lightning protection materials that can be used as part systems, we investigate some types electroconductive fabrics by applying several impulse currents in laboratory. Samples four commercially available textiles were analyzed, two rip-stop, a plain-weave, nonwoven, and additionally carbon-impregnated polymeric film. Under laboratory conditions, each sample was subjected to lengthwise subsequent lightning-like 8/20 us standard waveform, recording both voltage current signals. Optical scanning electron microscope observations performed after tests, revealing patterns or morphological changes on fabric surface. Despite these changes, investigated conductive withstand applied. Results suggest could personal mobile shelters, protect human beings against earth potential rise caused close discharge.
