Abstract

Apparatus and methods for joining nodes, extrusions, and panels are presented herein. Nodes, extrusions, and panels can be joined together using adhesive joining techniques. The adhesive joining techniques can be applied to additively manufactured nodes or extrusions, and sandwich panels. Sandwich panels can be additively manufactured and/or commercial off the shelf (COTS) components. There can be more than one type of a joint formed by the joining techniques. Exemplary types of j oints can use a liquid adhesive in conjunction with a vacuum and/or a film foam adhesive.

First claim

What is claimed is:

1 . An apparatus, comprising:
a component having a socket; a panel having an end portion positioned within the socket; and an adhesive between the end portion of the panel and the socket to adhere the panel to the component.

2 . The apparatus of claim 1 , wherein the panel is additively manufactured.

3 . The apparatus of claim 1 , wherein the component comprises a channel extending from an external surface of the component to the socket for adhesive injection.

4 . The apparatus of claim 3 , wherein the component further comprises a second channel extending from an external surface of the component to the socket for applying a vacuum during adhesive injection.

5 . The apparatus of claim 1 , further comprising a sealant between the end portion of the panel and the socket to seal the adhesive in the socket.

6 . The apparatus of claim 5 , wherein the sealant between the end portion of the panel and the socket reduces galvanic corrosion by forming a gap.

7 . The apparatus of claim 1 , further comprising a spacer between the end portion of the panel and the socket, the spacer separating a surface of the panel from a surface of the socket.

8 . The apparatus of claim 7 , wherein the surface of the panel is separated from the surface of the socket so as to reduce galvanic corrosion.

9 . The apparatus of claim 1 , wherein the panel comprises a plurality of adhesive patches extending across an edge of the end portion of the panel, the adhesive between the end portion of the panel and the socket extending from the adhesive patches.

10 . The apparatus of claim 9 , wherein the component comprises an additively manufactured node having one or more co-printed heat conductors thermally coupled to the adhesive patches.

11 . The apparatus of claim 1 , further comprising a node having a second socket at one end and a channel extending from the second socket to an opposite end of the node, wherein the component comprises an extrusion located in the second socket, and wherein the panel extends from the socket in the extrusion through the channel in the node.

12 . The apparatus of claim 11 , wherein a first portion of the adhesive is in the channel between the node and the panel, a second portion of the adhesive is in the socket between the extrusion and the panel, and a third portion of the adhesive is in the second socket between the extrusion and the node.

13 . The apparatus of claim 12 , further comprising a plurality of sealants arranged to seal the first, second and third portions of the adhesive from one another.

14 . The apparatus of claim 1 , wherein the component comprises two nodes adhered together to form the socket.

15 . The apparatus of claim 1 , wherein the panel comprises a hole, and wherein the component comprises a protrusion extending into the hole of the panel.

16 . The apparatus of claim 1 , wherein the component comprises an additively manufactured node having one or more co-printed grooves in the socket.

17 . The apparatus of claim 16 , wherein the one or more grooves comprises a first groove and a second groove, wherein the first groove and the second groove form a channel, and wherein the channel is configured to from a seal upon receiving an adhesive injection.

18 . The apparatus of claim 1 , wherein the component comprises an additively manufactured node having a plurality of weep holes.

19 . The apparatus of claim 18 , wherein the plurality of weep holes are for visually monitoring adhesive flow.

20 . The apparatus of claim 18 , wherein the plurality of weep holes are configured to allow adhesive flow unassisted by a vacuum or sealant.

21 . The apparatus of claim 1 , wherein the component comprises an additively manufactured node having a plurality of ports for air expulsion during adhesive injection.

22 . The apparatus of claim 1 , wherein the panel includes one or more thermocouples.

23 . The apparatus of claim 1 , further comprising an additively manufactured modular injector for adhesive injection in a selected region between the component and the panel, the modular injector further comprising a portion that seals the adhesive between the component and panel in the selected region.

24 . The apparatus of claim 1 , further comprising a punctured encapsulated adhesive tube located on an internal surface of the socket, the adhesive extending from the punctured tube into the socket.

25 . The apparatus of claim 1 , wherein the internal surface of the socket includes a notch, the punctured encapsulated adhesive tube being located in the notch.

26 . The apparatus of claim 1 , wherein the panel comprises a hole, and wherein the component comprises an additively manufactured node having a co-printed pin extending through the hole.

27 . The apparatus of claim 25 , further comprising a cap having a hole, wherein the distal end of the pin extends through the hole to secure the panel between the node and the cap.

28 . The apparatus of claim 1 , wherein the component further comprises an additively manufactured node having one or more grooves formed in the socket, the adhesive extending from the one or more grooves into the socket.

29 . The apparatus of claim 27 , wherein the end portion of the panel comprises a surface adjacent to the one or more grooves.

30 . The apparatus of claim 27 , wherein the end portion of the panel comprises first and second surfaces wherein:
the first and second surfaces comprise a core region between the first and second surfaces; and the one or more grooves includes a groove positioned along the core at an edge of the end portion of the panel.

31 . The apparatus of claim 1 , wherein the component comprises an additively manufactured node having a hole extending from the surface of the node to the socket to visually monitor adhesive flow.

32 . The apparatus of claim 1 , wherein the component comprises an additively manufactured node having one or more cups formed in the socket for adhesive or sealant overflow.

33 . A method of joining a panel of a transport vehicle, the method comprising:
obtaining a joining component, the joining component comprising a node; and adhering the panel to the joining component.

34 . The method of claim 33 , wherein the adhering the panel to the joining component comprises:
applying a film foam adhesive to an interface of the panel and the joining component; fixturing a joint between the panel and the joining component; and increasing the temperature of the adhesive so as to create an adhesive bond.

35 . The method of claim 33 , wherein the joining component further comprises an extrusion.

36 . The method of claim 33 , wherein the panel is additively manufactured.

37 . The method of claim 33 , wherein the node is additively manufactured.

38 . The method of claim 33 , wherein adhering the panel to the joining component further comprises:
inserting a spacer between the panel and the joining component, the spacer forming a gap between a surface of the panel and a surface of the joining component.

39 . The method of claim 38 , wherein the spacer forms the gap between the surface of t
