摘要： A low-temperature plasma treatment is applied to a surface of an aramid paper so as to allow the surface to have a compositional atomic ratio X (O/C) of the number of oxygen atoms (O) to the number of carbon atoms (C) ranging from 110% to 220% of a theoretical atomic ratio. The treatment is performed at an intensity ranging from 120 to 1500 W·min/m2 with a low-temperature plasma treatment apparatus of internal electrode system. The aramid paper is superposed with a nonhydrolyzable resin film and the resulting article is pressurized to give an aramid-resin film laminate. The laminate is inexpensive, has both superior electrical properties and high mechanical strength, excels in elasticity, and is useful as an insulation material.

摘要： An insulation sheet for electric machine that forms slot insulation sheet is configured by an aramid paper and a PPS film directly pressure laminated without use of an adhesive. This means that no adhesive layer interposes the aramid paper and PPS film. PPS film is less costly as compared to a polyimide film and possesses better thermal properties such as higher heat emissivity and is highly resistant to heat. Thus, high strength is maintained even when subjected to high temperature over extensive time. Further, because the aramid paper and PPS film are laminated directly without an adhesive layer, the laminate is reduced in thickness. This allows further thinning of the laminate.
