Creep and Creep-Rupture Behavior of a Continuous Strand, Swirl Mat Reinforced Polymer Composite in Automotive Environments

摘要

Creep and creep-rupture behavior of an isocyanurate based polyurethane matrix with a continuous strand, swirl mat E-glass reinforcement was investigated for automotive applications. The material under stress was exposed to various automobile service environments. Results show that environment has substantial effects on its creep and creep-rupture properties. Proposed design guide lines and stress reduction factors were developed for various automotive environments.
