The present invention describes a method for curing polymers and polymer composites with X-rays generated by the bremsstrahlung effect, using a high power, high energy electron beam. The process generates X-rays with sufficient throughput and penetration for commercial use. The present invention employs high power, high energy electron beams to create the X-rays. The beams are typically run at energies ranging from 1 MeV to 10 MeV, preferably from 3 MeV to 10 MeV, and more preferably from 5 MeV to 7 MeV. The beams typically have powers ranging from 30 kW or higher, preferably 80 kW or higher, more preferably 100 kW of higher, and ideally at least 200 kW. Suitable polymers and polymer composites include, but are not limited to, polymeric molding materials, fiber reinforced molding materials, reactive monomer impregnated wood, similar and dissimilar materials bonded through adhesives.

1. A method of curing a polymer forming material comprising the following steps: (i) placing an X-ray curable monomer, oligomer, pre-polymer, unsaturated or saturated material, or mixture thereof, within the interior of a mold; and (ii) exposing the exterior of the mold, one or more times, to X-ray
1. A method of curing a polymer forming material comprising the following steps: (i) placing an X-ray curable monomer, oligomer, pre-polymer, unsaturated or saturated material, or mixture thereof, within the interior of a mold; and (ii) exposing the exterior of the mold, one or more times, to X-ray photons generated by the bremsstrahlung effect, using an electron beam having an energy ranging from 1 MeV to 10 MeV and a beam power of at least 1 kW, wherein the X-ray photons penetrate the mold to fully cure the X-ray curable monomer, oligomer, pre-polymer, unsaturated or saturated material, or mixture thereof within the interior of the mold. 2. A method of curing a polymer forming composite material comprising the following steps: (i) placing an X-ray curable monomer, oligomer, pre-polymer unsaturated or saturated material, or mixtures thereof, and one or more reinforcement agents within the interior of a mold; and (ii) exposing the mold, one or more times, to X-ray photons generated by the bremsstrahlung effect, using an electron beam having an energy ranging from 1 MeV to 10 MeV and a beam power of at least 1 kW wherein the X-ray photons penetrate the mold to fully cure the X-ray curable monomer, oligomer, pre-polymer, unsaturated or saturated material, or mixture thereof within the interior of the mold. 3. A method of claim 1 or 2 where said mold is made of a metallic material. 4. A method of claim 1 or 2 where said mold is made of a plastic material. 5. A method of claim 1 or 2 where said mold is made of a ceramic material. 6. The method of claim 1 or 2 wherein the X-ray curable materials are reactive and the X-ray curing of said materials results in the production of near-zero volatile organic compounds (VOCs). 7. The method of claim 1 or 2 wherein the X-ray curable materials are selected from the group consisting of monomers, oligomers, pre-polymers, unsaturated or saturated materials. 8. The method of claim 1 or 2 where the electron beam has an energy ranging from 1 to 10 MeV. 9. The method of claim 1 or 2 where the electron beam has an energy ranging from 3 to 10 MeV. 10. The method of claim 1 or 2 where the electron beam has an energy ranging from 5 to 7 MeV. 11. The method of claim 1 or 2 where the electron beam has a power of at least 1 kW. 12. The method of claim 1 or 2 where the electron beam has a power of at least 30 kW. 13. The method of claim 1 or 2 where the electron beam has a power of at least 80 kW. 14. The method of claim 1 or 2 where the electron beam has a power of at least 100 kW. 15. The method of claim 1 or 2 where the electron beam has a power of at least 200 kW. 16. The method of claim 1 or 2 further comprising the step of rotating the mold during the step of exposing the mold to X-ray photons. 17. The method of claim 1 or 2 wherein the X-ray curable material comprises unsaturated material wherein the unsaturation is in the form of an acrylate and/or methacrylate vinyl functionality. 18. A method of curing a polymer forming material comprising the following steps: (i) placing a polymer forming material within the interior of a mold; and (ii) exposing the exterior of the mold, one or more times, to X-ray photons generated by the bremsstrahlung effect, using an electron beam having an energy ranging from 1 MeV to 10 MeV and a beam power of at least 1 kW, wherein the X-ray photons penetrate the mold to fully cure the polymer forming material within the interior of the mold. 19. The method of claim 18 wherein the polymer forming material consists of X-ray curable monomer, oligomer, pre-polymer, unsaturated or saturated material, or a mixture thereof.
