Non-Destructive Testing of Inhomogeneity of Wood Plastic Composite

Abstract:

The purpose of this study is to investigate of Non-Destructive Testing of Wood Plastic Composite (WPC), where the axis errors are mainly cracks caused by not change of cutting conditions (cutting speed and feed rate), respectively geometry of he cutting tool, but their imperfect encapsulation of wood with plastic (HDPE). Detection of surface defects was used visual inspection, colour penetrate test and fluorescent penetrate method. To detect internal defects was used X-ray. Pictures taken with a digital microscope camera does not provide sufficient information about internal defects, captures only the surface and as a result it is postulated that the cracks are spreading along the length of the profile extrusion axis (it is not possible to state their course in different layers – cross section along the thickness). Solution is use of the new technology – connection of metrology and tomography – metrotomography (X-ray scanning).
