<p>A method for forming a structural foam article having a cellular core, a high density integral skin with fiber reinforcement embedded therein, and exterior facing sheets so as to substantially avoid blistering of the facing sheets, is disclosed. The foam article is prepared by foaming an expandable resin composition between the fiber reinforcing material and facing sheets. The resin has a predetermined viscosity which is a direct function of the porosity of the reinforcing material and an indirect function of the foam initiation time.</p> |
