Abstract
Creep deformation behavior of an isocyanurate base polyurethane matrix with a continuous strand, swirl mat E-glass reinforcement was investigated for dimensional stability in automotive structural applications. Experimental data were generated in various simulated automotive service environments and analyzed to develop engineering models. Test results showed that environment had substantial effects on the creep deformation properties. Creep deformation design guide lines with respect to temperature, stress level and time have been proposed, environmental reduction factors for creep deformation suggested for automotive structural design applications.
