Summary

The effect of strong static magnetic field (SMF), i.e. magnetic field with constant strength in time to 19 T, on the epoxy resin, traditional matrix for composites has been studied. SMF exerts a substantial influence on the process of curing of epoxy resin resulting in an anisotropy of it's structure and properties. The effect of SMF resulted in an anisotropic linear thermal expansion coefficient and shift of glass-transition temperature. The wide-angle X-ray scattering showed a shift of the peak of the amorphous halo. The microhardness of cured epoxy resin with an increase in field strength attained the maximal level at approximately 8T.
