一种超声波透声复合材料的研究.

In this paper, a kind of ultrasonic transmission composite material is studied. Epoxy resin is used as adhesive material, metal powder with small acoustic impedance is added to improve the ultrasonic conductive performance, liquid rubber CTBN is added to toughen and modify, mercaptan curing and fatty amine accelerator are added to shorten the curing time, and a kind of composite material with good adhesive viscosity, good toughness, short curing time and ultrasonic penetration is developed functional composite materials with strong overactivity. It provides a solution to the problem that the transmission channel of the real-time monitoring system of ultrasonic rail breaking is cut off and the monitoring function cannot be played.
