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.

A method for manufacturing a glass fiber reinforced article, the method comprising: (a) spraying a mixture of chopped glass fiber and binder over a mold surface of a first mold section to form a glass fiber matrix, wherein the binder provides adhesive properties at room temperature so that the binder holds the chopped glass fiber in place;(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 and the binder to react and form a thermoset resin, wherein the process does include heating the binder. 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, 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. 9. 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. 10.

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. 13. A method according to claim 12, 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. 14. A method according to claim 12, 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. 15. A method according to claim 1, wherein the mixture of chopped glass fiber and binder comprises an organic solvent. 16. A method according to claim 1, wherein the binder has a viscosity of about 0.1 cps to about 100 cps at room temperature. 17. A method according to claim 15, wherein the organic solvent is provided with the binder in an amount of about 10 wt. % to about 70 wt. % organic solvent to combination organic solvent and binder. 18. A method according to claim 15, wherein the organic solvent is provided with the binder in an amount of about 30 wt. % to about 60 wt. % organic solvent to combination organic solvent and binder.
