Motyka describes Technetics Group's endeavor to develop a better seal starting with a new material. In the compressor section of a jet engine, abradable seals fill the gap between the turbine blade tips and the engine casing. During thousands of cycles between flight idle and high power, these seals perform the critical function of mitigating the leakage of air and gases that would rob the engine of propulsion and payload efficiency. A seal must be replaced once it decomposes too much due to erosion. In 2013, Technetics Group set out to make a new seal material and ultimately a new seal that would last longer and impart less wear on turbine blades compared to seals made of conventional materials, including today's widely used fiber-metals. In 2016 they completed rub tests on a new metal matrix composite, or MMC seal material.
