In this study the effect of moderate magnetic fields on the microstructure of a structural epoxy system was investigated. The changes in the microstructure have been investigated quantitatively using wide angle x-ray diffraction (WAXD) and pole figure analysis. The mechanical properties (modulus, hardness) of the epoxy were probed using nanoindentation. Using the continuous complex compliance analysis, the effect of the low magnetic fields on the viscoelastic properties of the epoxy was investigated. The phase lag angle was measured for both neat and magnetically annealed polymer. The results of this investigation reveal that under low magnetic fields both the quasi-static mechanical properties together with the viscoelastic behavior of the epoxy have been improved.
