Abstract:

The aim of the research was to set up a simplified analytical fabric-grounded object model for estimation of the energy stored in the electric field occurring in the space surrounding a charged fabric. A standard spherical electrode was used as the grounded object. Synthetic fabric with regularly spread conductive yarns (in the form of a grid with regular cells) was used as a sample. The model allowed to combine the energy stored in the space of the cell with the geometry of the fabric-object system and the surface charge density. The model led to a power type relation between the energy W and the cell, with a diameter of a, in the form K∙an, n ≈ 3. These results were verified by those obtained from numerical modeling using the COMSOL Multiphysics program. It was found that for a cell with a diameter of 10 to 50 mm, the difference in results was lower than 38%. Based on the results obtained, it can be stated that the model proposed can be used for the design of fabrics (used in ESD protection) with the maximum acceptable stored energy.
