Abstract

Near infrared (NIR) spectroscopy was used to characterize a set of medium-density fiberboard (MDF) samples. This spectroscopic technique, in combination with projection to latent structures (PLS) modeling, effectively predicted the mechanical strength of MDF samples with a wide range of physical properties. The stiffness, strength, and internal bond properties of the MDF samples could be predicted from the NIR spectra of the MDF surface. The technique is very rapid and provides molecular level insight on subtle changes in the properties of the MDF panels. The results highlight the potential value of NIR spectroscopy for process monitoring and quality control applications.
