The elastic moduli and mechanical damping of a range of polymeric restorative materials have been determined using a torsion pendulum. Composite materials have high moduli and low damping compared with unfilled resin. These materials have stable mechanical properties, but variation occurred as a result of different specimen conditioning methods. Non-destructive testing was valuable in that it allowed repeated testing of a single specimen.
使用扭摆测定了一系列聚合修复材料的弹性模量和机械阻尼。与未填充树脂相比，复合材料具有高模量和低阻尼。这些材料具有稳定的机械性能，但由于不同的试样处理方法而出现了变化。无损检测很有价值，因为它允许对单个试样进行重复测试。
