OPEN ACCESS
The use of the lignin–corundum hybrid fillers for phenolic resins was showed. The very important aspect of the use of lignin for phenolic resin composites is the reduction of phenol emission. The emission of phenol from the phenolic resin-hybrid filler composites were studied by headspace analysis. The physicochemical properties of the new hybrid fillers as well as the thermomechanical properties of the composites with them were examined. The surface properties of hybrid fillers were studied by inverse gas chromatography (IGC). The chemical structure of the new fillers was tested by Fourier transform infrared spectroscopy (FTIR). The dynamic mechanical thermal analysis (DMTA) was used to test the thermomechanical properties of the model composites for the use of abrasive tool production.
