Ornamentation of composites
View Patent ↗A method for decorating a composite placed in a mold in a resin transfer molding process includes selectively depositing unbonded pigments on one or more areas of a preform of the composite, and injecting a resin into the mold via one or more resin input ports operably connected to the mold. The injected resin carries the selectively deposited unbonded pigments on a path on one or more areas of the preform of the composite along a direction of flow of the injected resin, thereby creating ornamental pigment flow patterns in the composite for decorating the composite. The method also creates bands of ornamental pigment flow patterns by depositing the unbonded pigments on a transfer medium positioned on the composite, positioning the transfer medium in proximity to the resin input ports, and selectively injecting the resin onto the transfer medium deposited with the unbonded pigments, via the resin input ports.
1. A method for decorating a composite placed in a mold in a resin transfer molding process, comprising:
selectively depositing unbonded pigments on one or more areas of a preform of said composite;
applying a vacuum to said mold; and
injecting a resin into said mold for enabling a process of vacuum assisted resin transfer molding, wherein said resin is injected via one or more resin input ports operably connected to said mold, and wherein said injected resin carries said selectively deposited unbonded pigments on a path on said one or more areas of said perform of said composite along a direction of flow of said injected resin;
whereby ornamental pigment flow patterns are created in said composite for decorating said composite.
2. The method of claim 1 , wherein said composite is an artificial stone fiber composite comprising quartz particulates, glass particulates, fillers, and a polyester binder.
3. The method of claim 1 , wherein said vacuum is selectively applied through one or more vacuum ports selectively positioned over said composite in said mold, during said flow of said injected resin that carries said selectively deposited unbonded pigments on said path on said one or more areas of said preform of said composite, for creating different said ornamental pigment flow patterns in said composite.
4. The method of claim 1 , further comprising selectively injecting said resin premixed with pigments into said mold at one or different points of time.
5. The method of claim 1 , further comprising selectively injecting said resin into said mold via a plurality of resin input ports selectively positioned over said composite in said mold, for creating different said ornamental pigment flow patterns in said composite.
6. A method for creating bands of ornamental pigment flow patterns in a composite placed in a mold, in a resin transfer molding process, comprising:
depositing unbonded pigments on a transfer medium positioned on a preform of said composite;
positioning said transfer medium in proximity to one or more resin input ports operably connected to said mold; and
selectively injecting a resin onto said transfer medium deposited with said unbonded pigments, via said one or more resin input ports for creating said bands of said ornamental pigment flow patterns, wherein said injected resin carries said deposited unbonded pigments on a path on said perform of said composite along a direction of flow of said injected resin.
7. The method of claim 6 , wherein said transfer medium is a glass fiber strip.
