Nonscratching Windshield Wiper Blade
Abstract
The program was undertaken to assess the possible utilization of low friction and/or porous materials in making wiper blades for helicopter plastic windshields. It was, therefore, directed to a search for new materials rather than a comparison of materials in current use. A literature search was made to acquire the most recent information on the theories of wear and abrasion plus any specific literature on wiper blades for plastic windows. A synoposis of wear theory is presented, emphasizing the facets of the theory that apply to this problem. Ideal material characteristics are defined and a list of materials which approach one or more of these characteristics is presented. Some testing of promising materials was done. The test fixture used and the initial results are described. Recommendations for additional materials to be tested are made.
