Abstract: In this paper, a method for measuring Poisson's ratio of composite by real-time laser holograph is introduced. The fundamental principle of the method is described briefly. Some specimens made of ID aligned fiber with 0° and 90° angle CFRP and GRP plates are measured. It is understood that the method is very convenient and especially suitable for materials with rough surface and low value of Poisson's ratio.

摘要： 本文主要介绍了采用激光全息法测量材料泊桑比的方法,简要叙述了方法的基本原理,测量了0°和90°的单向碳纤维增强塑料(CFRP)板材和玻璃钢(GRP)板材的泊桑比。通过实验表明本法简便易行,特别适用于粗糙表面、小泊桑比材料的测量。
