Abstract
A method of forming a reinforced foam structure or laminate wherein a low density, fast reacting liquid foamable resin is sprayed under pressure into a low density fiberglass mat to penetrate and wet the fibers. The foam then expands within the fiberglass mat, forming a low density foam sheet having fiberglass distributed substantially continuously therethrough. A support or cover sheet is preferably laminated to the foam-fiberglass sheet and the laminate is formed under heat and pressure in a die into a contoured shape, simultaneously curing the resin foam.
