A Novel Use of a Composite Material to Limit the Loads in Windshield Wiper Systems 2001-01-0104
Using a thermoset polyester/glass fiber pultruded composite material, and taking advantage of column post-buckling behavior, a rigid/perfectly-plastic member can be approximated. Employment of the composite material is essential to realize an appreciable reduction in length of the member, while staying within the elastic range of the material. Utilizing this member as the connecting rod of 4-bar linkages found in automotive windshield wiping systems can limit the peak system loading occurring as a result of snow/ice pack above the cowl screen. This technology holds the potential for reliability, wipe quality, and cost improvement along with mass reduction in windshield wiping systems.
