Fundamental understanding on scratch behavior of polymeric laminates Conference Paper uri icon

abstract

  • Scratch-induced deformation mechanisms in polymers are known to vary with material properties and surface characteristics. Knowledge on how scratch-induced damage features are influenced by bulk mechanical and surface properties is thus highly desirable. Extensive experimental observations and modeling work have been carried out in our group to gain fundamental insights on how different scratch-induced damage mechanisms evolve in polymers. The formations of key scratch-induced deformation features that are responsible for scratch visibility and deleterious properties of polymer surfaces, such as scratch depth, shoulder height, fish-scale formation, parabolic cracking, and plowing along the scratch path, have been correlated with the bulk material parameters and surface properties of polymers. Some fundamental knowledge has thus been gained. Guidelines for preparation of scratch resistant polymers for engineering applications have also been proposed, and will be discussed.
