Overview

Numerical and experimental studies show that microstructures reduce leakage in gaskets, suggesting improved sealing efficiency.

Key Points

  • Introducing microstructures significantly reduces leakage between contact surfaces, enhancing sealing performance.
  • Numerical simulations indicated that optimal geometric parameters, like microprotrusion height, lower flow resistance.
  • Experimental results confirmed structured gaskets outperform quasi-smooth ones, especially at lower contact pressures.
  • A well-designed surface microstructure also intensifies local contact pressure, generating better sealing effectiveness.
