Molded articles prepared from flexible sheet molding compounds, and method of making the same. A flexibility modifying agent is incorporated into a thermoset resin composition (e.g. sheet molding compound) to improve the flexiblity characteristics of the thermoset resin compositon by lowering the flexural modulus. The thermoset resin composition also contains therein an isocyanate terminated urethane prepolymer; a thickening agent; a catalyst; a fibrous reinforcing material; and an inert filler.
