METHODS AND APPARATUS FOR FACILITATING RELATIVE SLIDEABLE MOVEMENT BETWEEN STRUCTURES

摘要

Methods and apparatus are provided for permitting relative slideable movement between structures. One or more slip membranes are positioned between first and second structures. The slip membranes reduce the coefficient of friction and/or break surface tension between the structures. The slip membranes may be chemically incompatible with one another and repel one another. The slip membranes may have a textured or non-smooth surface. Features provided on the slip membrane may facilitate drainage of fluid away from the structures or help with receiving or retaining lubricant material.
