Acoustic Emission Properties Of Frp Composite Damage

Abstract

The use of composite materials is very extensive, so we need to study the properties of these materials. In this paper, the tensile properties and fatigue properties of CFRP sheets are investigated experimentally, besides that, the method has certain reference value for obtaining corresponding application prospects and engineering background. The main work is to obtain the tensile and fatigue acoustic emission characteristics of CFRP sheets experimentally, the corresponding curve is given and its characteristic law is studied. The experimental results show that the carbon fiber plate has obvious acoustic emission characteristics in tension and fatigue, as well as the corresponding law.
