Abstract

Multilayer riblet applique and methods of producing the same are described herein. One disclosed example method includes applying a first high elongation polymer material to a web tool, where the web tool is to be provided from a first roll, and heating, via a first heating process, the first high elongation polymer material. The disclosed example method also includes applying a second high elongation polymer material to the first high elongation polymer material, and heating, via a second heating process, the second high elongation polymer material. The disclosed example method also includes applying, via a laminating roller, a support layer to the second high elongation polymer material.

First claim

What is claimed is:

1. A method of producing a multilayered riblet structure comprising:
applying a first high elongation polymer material to a web tool, the web tool provided from a first roll;
heating, via a first heating process associated with a first inline oven, the first high elongation polymer material as the first high elongation polymer material passes through an interior length of the first inline oven to cure the first high elongation polymer material;
applying a second high elongation polymer material to the first high elongation polymer material;
heating, via a second heating process associated with a second inline oven, the second high elongation polymer material as the second high elongation polymer material passes through an interior length of the second inline oven to cure the second high elongation polymer material; and
applying, via a laminating roller, a support layer to the second high elongation polymer material.

2. The method as defined in claim 1 , further including placing the multilayered riblet structure onto a rewind roll after the support layer has been applied.

3. The method as defined in claim 1 , further including:
placing the multilayered riblet structure onto a redirect reel after the support layer has been applied;
removing the web tool from the multilayered riblet structure; and
applying at least one of a masking or a liner to the multilayered riblet structure via pinch rollers.

4. The method as defined in claim 3 , further including applying a masking polymer coating to the first high elongation polymer material prior to applying the at least one of the masking or the liner.

5. The method as defined in claim 3 , wherein the web tool is removed via a removal roll.

6. The method as defined in claim 1 , wherein the second high elongation polymer material includes a color layer.

7. The method as defined in claim 1 , wherein at least one of the first or second high elongation polymer materials includes fluorosilicone.

8. A method of producing a multilayered riblet structure comprising:
dispensing a web tool from a first roll;
applying a first high elongation polymer material to the web tool;
applying, via a first roller, a riblet liner to the first high elongation polymer material to define a first layered construction;
placing the first layered construction onto a first rewind roll;
curing the first layered construction;
dispensing the first layered construction from the first rewind roll;
removing the riblet liner via a removal reel;
applying a second high elongation polymer material to the first high elongation polymer material;
applying, via a second roller, a support layer to the second high elongation polymer material to define a second layered construction;
placing the second layered construction onto a second rewind roll; and
curing the second layered construction.

9. The method as defined in claim 8 , wherein curing at least one of the first layered construction or the second layered construction includes moving the at least one of the first layered construction or the second layered construction through an oven via a conveyor.

10. The method as defined in claim 8 , further including at least partially curing the first high elongation polymer material prior to placing the first layered construction onto the first rewind roll.

11. The method as defined in claim 8 , wherein the second roller includes a nip roller.

12. The method as defined in claim 8 , wherein at least one of the first or second high elongation polymer materials includes fluorosilicone.

13. The method as defined in claim 1 , further including moving, via a conveyor, the first high elongation polymer material through the first inline oven and the first and second high elongation polymer material through the second inline oven.

14. The method as defined in claim 1 , wherein the first and second inline ovens are partially enclosed.

15. A method comprising:
casting a fluorosilicone riblet tip structure using web tool provided from a first roll, wherein casting the fluorosilicone riblet tip structure includes applying a first fluorosilicone material to the web tool as the web tool is unrolled from the first roll;
heating the flurosilicone riblet tip structure via a first inline oven to cure the fluorosilicone riblet tip structure;
applying a fluorosilicone layer to the fluorosilicone riblet tip structure, the fluorosilicone layer including a second fluorosilicone material;
heating the fluorosilicone layer via a second inline oven to cure the fluorosilicone layer; and
applying, via a laminating roller, a support layer adjacent to the fluorosilicone layer.

16. The method as defined in claim 15 , further including:
removing the web tool; and
applying at least one of a masking or a liner to the fluorosilicone riblet tip structure.
