A self-sealing nickel-titanium (NiTi) alloy double corrugated composite gasket was designed. The number of corrugation (5-7), the amplitude of corrugated (0.2-0.4 mm), the thickness of corrugated skeleton (0.5-1.0mm) and the seam width (0.2-0.4 mm) of the composite gasket were selected to design a four-factor and three-level experimental scheme by orthogonal experimental method. The ANSYS finite element software was used to study its compression resilience and sealing performance. The statistica software was used to process the data by multi-factor analysis of variance. The results showed that the corrugated number was the most significant factor affecting the resilience rate, and the slot width was the most significant factor affecting the compression rate. The optimal scheme for the resilience performance was obtained. The sealing performances of self-sealing composite gasket and common corrugated composite gasket were compared. The results showed that self-sealing composite gasket had better sealing performance.
