Abstract
The weak interface between aramid fiber and epoxy resin is the main reason why the mechanical performance of aramid fiber reinforced composites is greatly lower than that of aramid itself. The ultrasound technology of improving the wettability and the interface strength between epoxy resin and aramid fiber was used to increase the interface performance. The changes of the viscosity and the surface tension of the resin system after the ultrasonic treatment were studied, and then the wettability before and after the ultrasonic treatment was characterized. All these researches lay a foundation for the improvement of the interface performance of composites.
