Ground tire rubber filled polyurethanes: Effect of plasma surface modification.

摘要

Ground tire rubber powders were compounded into thermoset polyurethane matrices and cured. Surface modification of rubber particles was accomplished by using radio frequency O;Composite Young's modulus, tear resistance and ultimate stress increased with increasing Young's modulus of the matrix, with decreasing rubber volume fraction, or with decreasing rubber particle size.;Quadratic polynomial expressions were developed to predict composite properties. The polynomials better predicted the properties of high modulus composites and predicted the same trends that the experimental data established.
