Abstract

This project is designed to develop a process of vulcanization of retainers through microwaves and molds in compound materials, in accordance with the subject of a doctoral thesis. Work already carried out includes the study of the behavior of polymers and plastics to be used at industrial level microwave frequency (2.45 GHz), by placing pieces of material with wavelength guide ends (this stage was carried out jointly between OmniTek and the microwave laboratory of the Polytechnic School), and simulation of the behavior of the system in finite electromagnetic 3D elements (this stage was also carried out with the participation of OmniTek). The new stages include the theoretical sizing of the wavelength guides and sounding chamber, the design of the part to be manufactured and the mold in polymeric PEEK material plus 30 per cent carbon fiber and the establishment and study of method of injecting elastomers that are more appropriate to the project in question. It also includes the manufacture of an injector set and chamber supports to be installed in commercial injectors, injection and vulcanization testing and improvement of the process parameters. (AU)
