Title: Innovations by John Rhoat in Ceramic Matrix Composites
Introduction
John Rhoat is an accomplished inventor based in Wakefield, Rhode Island. He has made significant contributions to the field of ceramic matrix composites (CMCs) through his innovative patents. With a total of two patents to his name, Rhoat's work focuses on enhancing the performance and measurement capabilities of CMCs.
Latest Patents
Rhoat's latest patents include a "Temperature and thermal gradient sensor for ceramic matrix composites and methods of preparation thereof." This invention relates to a device that can be applied to the surface of CMCs, allowing the material itself to contribute to extraordinarily large thermoelectric power. The invention achieves greater resolution of temperature measurements, which can be obtained at exceedingly high temperatures.
Another notable patent is for "High resolution strain gages for ceramic matrix composites and methods of manufacture thereof." This patent describes strain gages designed for use with CMCs, utilizing the CMC as a strain element. For semiconductor CMCs, such as SiC fiber-reinforced SiC CMC, their large gage factor enables high sensitivity and accuracy in strain measurements at elevated temperatures. The strain gages can operate at temperatures exceeding 1600°C and can be configured to measure only the mechanical strain, independent of apparent or thermal strain.
