Changes of Electrical Parameters of Cement Chipboards Cetris-Basic after Freezing Cycle

Abstract

NDT impedance spectroscopy method was used to characterize a Cetris wood-cement chipboard. Dry specimen pre-stress and post-stress cycle tan δ (f) spectrum variances were observed. Effects of potential dielectric losses and the predominance of the polarization and conductivity components in various regions of the impedance spectrum of samples after frozen stress cycle are described. The method reproducibility has been verified by multiple measurements.
