Influence of different fillers on phenolic resin abrasive composites. Comparison of inverse gas chromatographic and dynamic mechanical-thermal analysis characteristics

Abstract

The resin resol with selected zeolites fillers and abrasive grain (fused alumina) in a form of cuboid were studied as model material of investigated composites. Inverse gas chromatography (IGC) was used to determine the degree of hardening of studied resol and resol in the filler-resol composites. Dynamic mechanical thermal analysis (DMTA) was used for assessment of the influence of different inorganic fillers on the thermo-mechanical properties of phenolic resin, applied as a binder in manufacturing of abrasive articles. The application of IGC method supported by DMTA analyses makes possible to assess filler/resin interactions and hardening of resin matrix. These results can be applied in industry of abrasive articles. Moreover, presented measurements are cost-effective - there is no need to produce trial product. It was evidenced that fillers reveal significant impact on the thermo-mechanical behaviour of model semi-product used for production of abrasive articles. © 2014 Elsevier Ltd.
