Beschreibung:
Composites of ceramic powders in epoxies appropriate for both insulating and impregnating NbTi windings are studied. Specific heat, thermal conductivity, thermal contraction, and magnetocaloric measurements on composites are presented. Thermal contractions well matched to copper are found and thermal shock resistance is greatly enhanced. Enthalpies, 4.2-6 K, range up to 80 mJ/cu cm and are 20-50 times larger than that of the pure epoxies. Results are not specific to the epoxies used but apply to composites with any amorphous matrices.
