The objective of this project was the investigation of a compaction process using high-power ultrasonic energy. The application of the ultrasonic process was focused on the compaction of composite materials, in particular brake pads for the car industry. The new technology aims for a fast high-quality compaction process.
A high-power ultrasonic press was constructed and tested. New composite materials and new types of glue were developed and optimised for the ultrasonic technology. The work was focused on the analysis of the technology and on the optimisation of the process parameters. Computer simulations were included in the project.
The advantages of the ultrasonic process is manifold. In particular the ultrasonic technology allows for a lighter press construction and shortening the production time. In particular the pressing and the curing cycle can be shortened. One other major advantage was the increased fading coefficient.
