Abstract:
The development and relaxation of stresses in epoxy matrix-filler systems were studied experimentally under isotropic thermal and baric effects. Data on the nuclear quadrupole resonance of the filler crystals were analyzed using an empirical model for the relaxation processes in the matrix of the composite material. The effective stress-relaxation time was found to depend on the temperature, external pressure, and the magnitude and type of deformations of the polymer matrix.
Keywords:
relaxation, granular composites, nuclear quadrupole resonance.
