Abstract

Bobbins, such as those used for magnets, that are made of glass filled polymers exhibit unsatisfactory deformation when subjected to high temperatures. While carbon filled bobbins are more satisfactory, specially for heat resistant characteristics, the use of carbon fiber filled nylon improves the operating temperature of bobbins by approximately 70 Degrees C. Bobbins made of glass fiber filler failed to operate at approximately 170 Degrees C, while bobbins made of carbon fiber filled nylon failed to operate at approximately 240 Degrees C. The use of a filler, such as carbon fiber, also improves the heat and electrical conductivity of the material.
