摘要

<正> By means of ultrasonic attenuation apparatus

the ultrasonic velocity and attenuation ofanhydride-cured epoxy resins （EP）/poly （ethylene oxide）（PEO） blends were measured on thebasis of pulse-echo method. It was found that the sonic velocity of the blends decreased as thetemperature increased

but attenuation coefficient increased and possessed a peak value. Largervelocity and smaller attenuation coefficient（α）can be obtained from perfect crosslinking networkstructures of pure DGEBA cured with phthalic anhydride（PA）. As for cured DGEBA/PEO blendsystems

sonic velocity decreased as a function of PEO concentration

but attenuation coefficient（α） increased.

Abstract

By means of ultrasonic attenuation apparatus

sonic velocity decreased as a function of PEO concentration

but attenuation coefficient（α） increased.
