MATERIAL CHARACTERISTICS OF PREFORMED BEARING PADS
Preformed fabric (commonly known as "cotton duck") material made to Mil-C-882E specifications has been used for years as vibration isolation pads in structures. High strength characteristics and resistance to bulging make this material well suited for slide bearing and fixed bearing applications. Published behavior data and design guidelines have not been readily available for the use of preformed fabric material. This paper describes the results of a comprehensive test program designed to provide potential users with test data for uniform and nonuniform compression, creep and shear behavior. Based on the resulting data, the authors suggest design parameters for the use of preformed fabric material in structural applications.
