The demand of fuel economy for reduced motor vehicle weight has led to widespread interest in high modulus reaction injection molded urethane (RIM) for automotive exterior parts as well as for many non-automotive applications. Reinforcing fibers and fillers, combined with the versitility of urethane chemistry, are important parameters for achieving composites with stiffness and toughness while reducing coef ficients of thermal expansion.
