  1. 1.

    The components of the complex permittivity in the ILF range have the greatest variation in accelerated aging of glass-reinforced plastics by boiling in water. In addition such properties as the ultimate bending strength, the logarithmic decrements under torsional and flexing vibrations, the components of the complex permittivity in the radio-frequency range, and the light-transmission factor undergo profound change. Boiling shows a smaller effect on the change in the propagation rate of ultrasonics and on the dynamic moduli of elasticity under longitudinal and flexing vibrations and shear.

  2. 2.

    Unlike the majority of physicomechanical properties, which indicate mainly the initial changes in the strength properties of a glass-reinforced plastic, the components of the complex permittivity to a first approximation have a linear dependence on the ultimate bending strength, the absolute variations of these properties diminishing with an increase in the frequency.
