Wear and Erosion Resistance of Aircraft Engine Composite Elements in a Gas Abrasive Flow

Abstract

The results of the experimental study of the structural carbon fiber reinforced plastic (CFRP) erosion resistance applied to gas turbine engine structural elements are presented. A methodology for characterizing the process of gas abrasive wear of thin-walled structures made of polymer composite materials has been developed. The factors are found that determine the level of the abrasive effect of dust and gas mixture formed at the take-off and landing. A criterion for material erosion resistance assessment is presented.
