A glass fiber reinforced article can be manufactured by: applying a mixture of glass fiber and binder over a mold surface of a first mold section to form a glass fiber matrix, wherein the binder comprises an organic solvent based binder capable of holding the glass fiber in place at room temperature
A glass fiber reinforced article can be manufactured by: applying a mixture of glass fiber and binder over a mold surface of a first mold section to form a glass fiber matrix, wherein the binder comprises an organic solvent based binder capable of holding the glass fiber in place at room temperature; closing a second mold section over the first mold section to form a plenum between the first mold section and the second mold section, wherein the glass fiber matrix is provided in the plenum between the first mold section and the second mold section; injecting a reactive polymer forming composition into the plenum; and allowing the reactive polymer forming composition to react and form a thermoset resin. A glass fiber reinforced article is provided according to the invention.

We claim: 1. A method for manufacturing a glass fiber reinforced article, the method comprising: (a) spraying a mixture of glass fiber and binder over a mold surface of a first mold section to form a glass fiber matrix, wherein the binder comprises a reactive binder and an organic solvent, and is capable of holding the glass fiber in place at room temperature; (b) closing a second mold section over the first mold section to form a plenum between the first mold section and the second mold section, wherein the glass fiber matrix is provided in the plenum between the first mold section and the second mold section; (c) injecting a reactive polymer forming composition into the plenum so that the reactive polymer forming composition infuses with the glass fiber matrix; and (d) allowing the reactive polymer forming composition to react, and react with the reactive binder, and form a thermoset resin. 2. A method according to claim 1, further comprising a step of applying a gel coat over the mold surface of the first mold section prior to the step of applying a mixture of glass fiber and binder. 3. A method according to claim 2, further comprising a step of applying a barrier coat over the gel coat prior to the step of applying a mixture of glass fiber and binder. 4. A method according to claim 1, wherein the glass fiber reinforced article comprises a boat hull. 5. A method according to claim 1, wherein the glass fiber reinforced article comprises about 20 wt. % to about 80 wt. % of the reactive polymer forming composition. 6. A method according to claim 1, wherein the glass fiber reinforced article comprises about 20 wt. % to about 60 wt. % of the glass fiber. 7. A method according to claim 1, wherein the reactive polymer forming composition comprises an unsaturated polyester forming composition. 8. A method according to claim 1, further comprising a step of reacting the reactive polymer forming composition and the binder to form the thermoset. 9. A method according to claim 8, wherein the reactive polymer forming composition comprises at least one of polyester, vinyl ester, acrylic polymer, polyepoxide, aminoplast, alkyd resin, polyamide, polyolefin, polyurethane, vinyl polymer, phenolic resin, or mixtures thereof. 10. A method according to claim 1, wherein the reactive polymer forming composition comprises at least one of curing catalyst, viscosity modifying agent, mold release agent, filler, pigment, opacifier, or mixture thereof. 11. A method according to claim 1, wherein the binder comprises an unsaturated polyester resin. 12. A method according to claim 1, wherein the binder comprises acrylic urethane. 13. A method according to claim 1, wherein the mixture of glass fiber and binder comprises about 80 wt. % to about 98 wt. % of the glass fiber and about 2 wt. % to about 20 wt. % of the binder. 14. A method according to claim 13, further comprising a step of applying a layer of continuous strand fiber over the mold surface prior to the step of closing a second mold section over the first mold section. 15. A method according to claim 13, further comprising a step of applying a second layer of fiber matrix over the mold surface prior to the step of closing a second mold section over the first mold section.
