| Abstract: | It is well known that crazing occurs sometimes when a magnet wire is immersed in an impregnating varnish after coiling. A quantitative study between residual stress of a magnet wire film and crazing is presented in this paper by using a magnet wire having poor adhesive strength between the film and the conductor. The residual stress of a magnet wire was found to be maximum in the range of 3–5% elongation. A morphological study of crazing which occurred in crosslinked and linear polymers is also described in this paper. |
