摘要
Abstract
Pores in CFRP samples were characterized by metallography and ultrasonic attenuation coefficient. The effect of pore morphology on ultrasonic attenuation was researched. The results show that ultrasonic attenuation coefficient is increasing with the increase of pore geometric morphology parameter; the slope of average pore length-porosity is bigger than of width-porosity; ultrasonic attenuation coefficient is decreasing with the increase of the percentage of pores in main sizes; ultrasonic attenuation coefficient is increasing with the increase of the percentage of big pores at the same porosity. In short, the pore morphology has some influence on ultrasonic attenuation and can not be ignored.
