Extent of conversion and its effect on the mechanical performance of Bis-GMA/PEGDMA-based resins and their composites with continuous glass fibres.
The reaction mechanism of bisphenol A bis(2-hydroxy propyl) methacrylate (Bis-GMA) and polyethylene glycol dimethacrylate (PEGDMA) was characterized by differential scanning calorimetry (DSC) and infrared (IR) spectroscopy. Composites of S2-glass fibres with different formulations of Bis-GMA/PEGDMA were fabricated by filament winding. The mechanical properties of neat resins and composites were investigated by dynamic mechanical thermal analysis (DMTA) and a three-point-bending flexural test.
