As a supplement to our investigation into R-curves in a short-fiber reinforced dental resin composite, we investigate the effects of 2-months water storage. Water is known to degrade the siloxane bonds linking matrix and fillers, which has been suggested to decrease the fracture toughness in conventional resin composites. However, fiber-reinforced systems seem to be less affected as the toughness is dependent on fiber bridging, which is only effective if a weaker interfacial bond between fiber and matrix is present.

储水后短纤维增强树脂复合材料的R曲线行为。

作为对短纤维增强牙科树脂复合材料中R曲线研究的补充，我们研究了2个月储水的影响。已知水会降解连接基体和填料的硅氧烷键，这被认为会降低常规树脂复合材料的断裂韧性。但是，由于韧性取决于纤维桥联，因此纤维增强体系似乎受到的影响较小，这仅在纤维与基质之间存在较弱的界面键合时才有效。
