Abstract: The subject invention discloses a composite structure and a resin component for use in the composite structure. The composite structure includes a first layer, comprising a styrenated unsaturated polyester, and a second layer. The first layer is a show surface of the composite structure. The second layer includes the reaction product of the resin component and an isocyanate component.
