Method for testing dielectric adequacy and for indicating physical defects in a nonconducting material by depositing traces of carbon on the material |
摘要 |
An elastomer impregnated with carbon is utilized in conjunction with a conductor to test the dielectric adequacy of a nonconductor and to indicate physical defects, such as cracks, pinholes or a thickness below a predetermined minimum, by depositing traces of carbon on the nonconductor in the area of the defect or the area where the thickness is below the predetermined minimum.
