Viscoelastic Loss Characteristics of Cord Rubber Composites. Final Report, September 1, 1980-August 31, 1983

摘要

The viscoelastic loss characteristics of cord rubber composites are important in reducing the hysteretic losses of all reinforced products in the rubber industry, with particular attention to automobile tires. Both analytical and experimental programs were undertaken to define the cord rubber loss characteristics, and agreement was satisfactory between theoretical prediction and experimental measurement. Predictions were based on conversion to complex form of the Halpin-Tsai equations for defining the elastic properties of a single sheet of rubber coated fabric. Tubular specimens were subjcted to both cyclic tension and cyclic torsion as a measure of their internal loss characteristics. (ERA citation 09:000819)
