Damage of RFC Surface Layers by Electrostatic Charging,
HOCHSCHULE DER BUNDESWEHR HAMBURG (GERMANY F R)
Pagination or Media Count:
Painted RFC-material has been tested by extremely high electrostatic charging. Charge densities reached some hundreds of nanocoulombs per square centimeter on thin surface layers. The resulting high field strength in the dielectric leads to an electric breakdown with or without mechanical damage depending on material thickness and the conductivity of any grounded layer next to the surface. The time-dependent development of the entire local charge distribution was monitored by a computer-controlled measuring system. In any case, there was little influence of a damaged point on the discharging or recharging process. Author
