Evaluating thermal properties of sugarcane bagasse-based composites by using active infrared thermography and terahertz imaging
This study is devoted to the analysis of impact damage in composite samples by applying techniques of IR and
Terahertz imaging. The samples made of high-density homogeneous particleboards of sugarcane bagasse and
castor oil polyurethane resin were subjected to impacts with the energy from 5 to 30 J. The impact damage
defects were evaluated by applying one- and two-sided thermal non-destructive testing. Both the apparent
thermal effusivity and diffusivity were determined to analyse their relationship to impact energy. In the abovementioned
