ISO 178 塑料的弯曲性能
ISO178研究塑料的弯曲属性，以确定弯曲强度、弯曲模量，以及弯曲应力/应变关系的其他方面。
此ISO178试验方法适用于挤塑塑料（填充和非填充型）、刚性热塑性片材和热固性模塑塑料（包括填充和增强的模塑塑料）。三点和四点加载弯曲夹具均可用于对这些材料进行评估。当执行四点弯曲试验时，从历史角度看，直接弯曲测量通常需要使用挠度计或其他应变测量装置，如引伸计或LVDT。在ISO178的2010版之前，三点弯曲试验不要求使用直接应变测量装置。要求按照ISO 178修订版进行试验之前，有五年宽限期。因此，到了2015年，用户必须遵守ISO178要求，在测量模量时使用应变测量装置。
弯曲夹具的支撑跨距要求应以试样厚度比率为基础。选择夹具之前，先了解试样尺寸范围非常重要。加载和支撑砧的尺寸大小可能会因试样厚度的不同而不同。在这里，对于三点弯曲试验，我们将结合使用AutoX 750和挠度计直接测量应变。AutoX的传感器臂夹住挠度计，以精确测量直接应变，并依照ISO178确定试样的弯曲性能。
我们建议您重温ISO178的各项内容，以完全理解试验夹具和结果要求。
