Abstract

A system and process for bonding involves a pocket made into one article is used to secure that article to another using a flowable, curable material (e.g., resin) which during saturation enters through a passageway and at least partially fills the void. When the article is cured, the article is bonded to another article to which resin has also been applied since the void (now containing cured material) is larger than the passageway.

Claims (39)

1. A process comprising:

providing a first material;

growing a part of a second material, the part having at least one surface;

defining, while growing the part, at least one pocket in the part, and further defining a passageway from the at least one pocket to the at least one surface;

applying the first material onto the at least one surface of the part;

introducing the part to a flowable, curable resin saturated into the first material and then traveling through the passageway to enter into and at least partially fill the at least one pocket; and

curing the resin to create a bond between the first material and the part.

2. The process of claim 1 wherein the first material is resin satiable and fiberous.

3. The process of claim 1 wherein the resin is a thermoset resin.

4. The process of claim 1 wherein the resin is a thermoplastic resin.

5. The process of claim 1 wherein the growing step is executed using one of a 3-D printing, a composite layup, and a casting process.

6. The process of claim 5 wherein the step of defining the at least one pocket in the part comprises:

sizing the at least one pocket to have a cross-sectional dimension larger than a dimension of the passageway such that the resin will be retained within the at least one pocket after being cured.

7. The system of claim 1 wherein the part is constructed through an additive manufacturing process, and the first material is constructed by stacking carbon fiber layers.

8. A fastening process comprising:

growing a first article to define a first passageway, into the first article below a first attachment surface, the first passageway leading into an enclosed first void formed into and underneath the first attachment surface;

sizing a void cross section in the first void to have a dimension that is greater than at least a portion of a cross sectional dimension in the first passageway;

causing a curable fluid to be introduced into a second article applied onto the first attachment surface, the curable fluid, after being introduced, passing into the first passageway and then into the first void to at least partially fill the first void; and

curing the fluid to secure the first article to the second article.

9. The process of claim 8 comprising:

configuring a second surface of the first article to have a second void, and

introducing the curable fluid into the second void to secure the first article to a third article on an opposite side of the first article from the first attachment surface.

10. The process of claim 8 comprising:

substantially saturating the second article with the curable fluid before the curing step.

11. The process of claim 10 comprising:

providing a fiber material in a process of constructing the second article; and

completing the second article in executing the curing step creating a first integrated connection between a body of the second article and the first void via a first cured mass of the curable fluid.

12. The process of claim 11 comprising:

providing the fiber material in a process of constructing a third article; and

completing the third article in one of: (i) executing the curing step; and (ii) executing an additional curing step; to create a second integrated connection between a body of the third article and a second void via a second secured mass of the curable fluid.

13. The process of claim 12 comprising:

using the first article to secure the second and third articles together to form an aircraft part.

14. The process of claim 8 wherein a configuring step comprises:

growing a material layer by layer to form the first article such that the first void and first passageway are included in the first article.

15. The process of claim 14 comprising:

wherein the growing step is executed using a 3-D printing process.

16. The process of claim 8 comprising:

constructing the first article of a plastic using an additive manufacturing process; and

constructing the second article of composite materials.
