Ultrasonic Characterization of Epoxy Composites Reinforced by Glass Powder

Abstract

The aim of this work is to find relationships between the selected parameters of an ultrasonic waves and the glass powder content in an epoxy composites . Epoxy composites materials with 10% , 20% , 30% , 40% , 50% and 60% glass powder volume fraction were all examined by means of pulse-echo ultrasonic . The experimental results showed relationships between , ultrasonic echo amplitude response , ultrasonic attenuation , ultrasonic velocity and glass powder content in the investigated composite materials. This study has also assessed the ability of pulse-echo technique to carry out such testing . The described method can be applied to the post-production quality control of a finished composite products and has great importance for products with a high failure-free requirements . Keywords
