Degradation of Terfenol-D particle epoxy composites under low frequency cyclic magneto-mechanical loading: comparisons of matrix polymer

摘要

Magnetostrictive Terfenol-D particle actuated epoxy polymer matrix composites were prepared with polyamine and anhydride cured epoxy polymer matrices. The different matrix epoxies exhibited large differences in glass transition and creep behavior. The differences in matrix thermal-mechanical properties resulted in important differences in temperature dependant damage behavior and magneto-elastic strain output in the Terfenol-D particle actuated epoxy polymer matrix composites.
