Non-destructive testing of fiber-cement boards using time domain terahertz spectroscopy

Tomasz Chady, Krzysztof Schabowicz

The article proposes the use of NDT method utilizing electromagnetic waves with frequencies in the terahertz range for the inspection of fiber-cement boards. First, the most frequently appearing material defects in the plates, are presented. The measurements of defective and flawless plates were carried out using the terahertz method and the selected results are presented. The preliminary tests have confirmed the usefulness of the proposed method for testing fiber cement boards.
