Izod impact toughness. (A) Results for full fracture at high strain rate are charted, demonstrating remarkable toughness improvements when fiber reinforcement is added to particulate-filled dental pastes (each value is the group mean for 5 sample tests; error bars ± 1 standard deviation). (B) SEM (scale 5 microns) characterizes particulate-filled commercial composite Z100 with minimal debonding. (C) SEM (scale 5 microns) depicts reinforced Z100 with transverse fractured quartz fibers providing a large irregular debonding surface area. Particulate-filled composite essential for fiber-reinforced molding and radiopacity still resides between individual fibrils and as shattered debris.
