Abstract
Official abstract text for this publication.
A method of manufacturing a workpiece includes heating a pre-formed blank of a first fiber reinforced thermoplastic material in an oven. A second fiber reinforced thermoplastic material is heated in an extruder. The second fiber reinforced thermoplastic material is extruded from the extruder, within the oven, to form an extrudate. The extrudate is positioned on the pre-formed blank of the first fiber reinforced thermoplastic material, within the oven, to form a composite blank. The extrudate may be formed into a shape before being positioned onto the pre-formed blank, after being positioned onto the pre-formed blank. The composite blank may then be transferred to a final shaping station.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a composite blank, the method comprising: heating a pre-formed blank of a first fiber reinforced thermoplastic material in an oven; heating a second fiber reinforced thermoplastic material in an extruder; extruding the second fiber reinforced thermoplastic material from the extruder to form an extrudate; positioning the extrudate on the pre-formed blank of the first fiber reinforced thermoplastic material within the oven to form the composite blank; and transferring the composite blank to a final shaping station. 2. The method set forth in claim 1 , wherein the extrudate of the second fiber reinforced thermoplastic material is extruded from the extruder directly onto the pre-formed blank of the first fiber reinforced thermoplastic material. 3. The method set forth in claim 1 , further comprising forming the extrudate of the second fiber reinforced thermoplastic material into a pre-form within the oven. 4. The method set forth in claim 3 , wherein forming the extrudate into the pre-form is further defined as forming the extrudate into the pre-form before positioning the extrudate on the pre-formed blank of the first fiber reinforced thermoplastic material. 5. The method set forth in claim 3 , wherein forming the extrudate into the pre-form is further defined as forming the extrudate into the pre-form after positioning the extrudate on the pre-formed blank of the first fiber reinforced thermoplastic material. 6. The method set forth in claim 3 , wherein forming the extrudate into the pre-form includes forming the extrudate into a sheet. 7. The method set forth in claim 6 , wherein forming the extrudate into the pre-form includes trimming the sheet into a pre-defined shape. 8. The method set forth in claim 7 , wherein positioning the extrudate of the second fiber reinforced thermoplastic material on the pre-formed blank of the first fiber reinforced thermoplastic material includes placing the pre-defined shape of the extrudate on the pre-formed blank of the first fiber reinforced thermoplastic material. 9. The method set forth in claim 1 , wherein the first fiber reinforced thermoplastic material and the second fiber reinforced thermoplastic material each include one of glass fibers or carbon fibers. 10. The method set forth in claim 1 , wherein the first fiber reinforced thermoplastic material and the second fiber reinforced thermoplastic material each include one of a polyamide or polypropylene material reinforced with one of carbon fibers, glass fibers, or mineral fillers. 11. The method set forth in claim 1 , wherein the second fiber reinforced thermoplastic material is virgin material. 12. The method set forth in claim 1 , wherein the second fiber reinforced thermoplastic material is recycled material. 13. A method of manufacturing a composite blank, the method comprising: heating a pre-formed blank of a first fiber reinforced thermoplastic material in an oven; heating a second fiber reinforced thermoplastic material in an extruder; extruding the second fiber reinforced thermoplastic material from the extruder, within the oven, to form an extrudate; positioning the extrudate on the pre-formed blank of the first fiber reinforced thermoplastic material, within the oven, to form the composite blank; and transferring the composite blank to a final shaping station. 14. The method set forth in claim 13 , further comprising forming the extrudate of the second fiber reinforced thermoplastic material into a pre-form before positioning the extrudate on the pre-formed blank of the first fiber reinforced thermoplastic material. 15. The method set forth in claim 13 , further comprising forming the extrudate of the second fiber reinforced thermoplastic material into a pre-form after positioning the extrudate on the pre-formed blank of the first fiber reinforced thermoplastic material. 16. A method of manufacturing a composite blank, the method comprising: heating a pre-formed blank of a first fiber reinforced thermoplastic material in an oven; heating a second fiber reinforced thermoplastic material in an extruder; extruding the second fiber reinforced thermoplastic material from the extruder to form an extrudate; forming the extrudate of the second fiber reinforced thermoplastic material into a pre-form within the oven; positioning the extrudate on the pre-formed blank of the first fiber reinforced thermoplastic material to form the composite blank; and transferring the composite blank to a final shaping station. 17. The method set forth in claim 16 , wherein extruding the second fiber reinforced thermoplastic material is further defined as extruding the second fiber reinforced thermoplastic material in the oven.
