Abstract

Abstract:

Leakage and wear of a finger seal are two key factors that affect seal dynamic performance and service life. Optimum design of a finger seal structure is difficult to realize because of the mutual suppression between the two factors in seal performance improvement. Carbon-carbon composites are applied to finger seal component preparation to improve seal performance for its self-lubrication property, which may prove to be a most feasible solution to this issue. It is meaningful work to carry out an analysis for carbon-carbon composite finger seal performance to provide the theoretical basis for its design. This paper evaluated the elastic properties of the materials by using the constituent material properties to calculate the stiffness matrix of the 2.5D carbon-carbon composites, and established a finite element model for carbon-carbon composite finger seal dynamic performance analysis. By this model, the effects of yarn density and weaving mode on the dynamic performance of finger seals are studied. The results show that increasing the yarn density in the circumferential direction of the finger seal and using shallow direct-joint structure can improve the finger seal dynamic performance. Finally, compared with metalseals, the 2.5D carbon-carbon composite finger seal exhibits better seal dynamic performance. The study shows that it is feasible to use carbon-carbon composites for finger seal component preparation.

Key words: carbon-carbon composites, finger seal, stiffness matrix, dynamic analysis, displacement response, contact pressure
