Patent ID: 7776392

Claim:
A method for impregnating a composite tape with high thermal conductivity (HTC) particles comprising: permeating a fabric layer of said composite tape with HTC particles; and impregnating an impregnating resin into said composite tape through said fabric layer; wherein said permeating comprises selectively permeating the fabric layer with a first group of the HTC particles that will be mobile in the impregnating resin during said impregnating and selectively permeating the fabric layer with a second group of the HTC particles that will remain stationary in the fabric layer during said impregnating; and wherein, during said impregnating, at least 1% of said first group and said second group of HTC particles permeated into said fabric layer are carried out of said fabric layer and into a mica layer bound to said fabric layer by said impregnating resin.
