Designing an Ultrasonic System Used to Reduce the Cross‐Linking Time of Epoxy Resins Used in the Construction of Brake Cylinders

Ultrasounds and their applications constitute fields of theoretical and practical research with applicability starting with the military, medicine, automotive industry, and ending with household appliances. The use of ultrasonic field in the cross‐linking of epoxy resins reduces the time required to produce composite structures, independent of the type of reinforcing components used. Brake cylinders, made by successive deposition of two layers of epoxy resin and quartz sand used in applications where frictional forces are very high, constitute a challenge for composite structures. The article presents the analytical calculation and the design of the ultrasonic system used in making a sample made of metallic base material and two layers of epoxy resin reinforced with quartz sand. Using this new proposed technology, there is a substantial reduction in the time required to solidify the structure and the elimination of the need for a high temperature necessary to carry out the traditional technological process.
