The influence of ultrasound on physico- mechanical properties of composite materials reinforced with carbonaceous fibers in the formation process

摘要

The process of reinforcement in the ultrasonic field of structural elements from ABS plastic composite structures containing carbon fibers was studied. The fact of formation of an adhesive-strong interface of "composite-plastic" under the action of ultrasound on the sample during the curing of the composite is established. It is shown that ultrasonic action causes the formation of a homogeneous morphology of the surface and structure of the composite layer, as well as a change in the ratio of the strength parameters of the material. In tensile tests, an increase in strength of 18 % was found with a certain decrease in the elongation.
