Abstract

Presented an overview of heat-resistant fibers and nonwovens based on them. Their comparative characteristics, description, advantages and disadvantages for use as a basis for the use of afterburner regulators of gas turbine engines as part of air filters. The conclusion is made about the possibility of using nonwovens and the prospects for their application, as well as about a possible way to improve the characteristics of nonwovens to adapt to operating conditions at elevated and lowered temperatures.
