Abstract
A process for manufacturing a composite article includes forming a base component of a base material and forming a structure on the base component by applying a fluid mixture to the base component. Applying the fluid mixture to the base component includes forcing the fluid mixture into a mold cavity in which the base component is disposed. The fluid mixture includes molten plastic and an additive that is reactive with the base material.
Claims24
A method of manufacturing a bottle, the method comprising:
- forming a vessel of metal;
- and
- forming a structure on the vessel by applying a fluid mixture to the vessel, wherein the fluid mixture comprises a molten substance and an additive, wherein the molten substance is a plastic and the additive is reactive with the metal such that the additive reacts with the metal to form a bond layer joining the structure to the vessel.
A method of manufacturing a composite container, the method comprising:
- forming a vessel of glass, wherein the vessel defines an interior space and comprises an outer surface that faces away from the interior space;
- and
- forming a coating on the vessel by applying a fluid mixture to the outer surface, wherein the fluid mixture comprises a molten substance and an additive, wherein the molten substance is a plastic and the additive is reactive with the glass such that the additive reacts with the metal to form a bond layer joining the coating to the vessel.
The method of 11, wherein the chemical reaction comprises oxidation of the glass.
A composite article comprising:
- a vessel formed of a base material, wherein the base material is metal or glass;
- a structure formed on the vessel, wherein the structure comprises plastic;
- and
- a bond layer joining the structure to the vessel, wherein the bond layer comprises a product of a chemical reaction between the base material and a substance comprised by the structure.
