Multi-directional load joint system
A structural joint includes a first member having a first base portion and a first leg portion. The structural joint further includes a second member having a second base portion and a second base portion. The first base portion and the second base portion are coupled together at an overlapping portion. The first leg portion and the second leg portion form a cavity for structurally coupling to a structural member.
1. A structural joint comprising:
a first member having a first base portion and a first leg portion; and
a second member having a second base portion and a second leg portion;
wherein the first base portion and the second base portion are coupled together at an overlapping portion;
wherein the first base portion and the second base portion are coupled to a skin;
wherein only the first base portion is in contact with the skin;
wherein the second base portion is smaller than the first base portion;
wherein the first leg portion and the second leg portion form a cavity for structurally coupling to a structural member; and
wherein the first member and the second member are “L” shaped.
2. The structural joint according to claim 1 , wherein the first base portion and the second base portion are coupled together with an adhesive.
3. The structural joint according to claim 1 , wherein the first base portion and the second base portion are coupled together with a fastener.
4. The structural joint according to claim 1 , wherein the first base portion and the second base portion are coupled to the panel skin with an adhesive.
5. The structural joint according to claim 1 , wherein the structural member is a structure in an aircraft.
6. The structural joint according to claim 1 , wherein the structural member is a panel having a first face, a second face, and a core disposed therebetween.
7. The structural joint according to claim 1 , wherein the first member and the second member are cured composite material.
8. The structural joint according to claim 1 , wherein the first base portion and the second base portion are scarfed at the overlapping portion.
9. The structural joint according to claim 1 , wherein the second member is located top of the first base portion of the first member.
10. A joint system for attaching a panel to a skin, the system comprising:
a first member having a first leg portion, and a first inner base portion, the first inner base portion being coupled to the skin along a first bonding surface; and
a second member having a second leg portion, a second inner base portion, the second inner base portion of the second member being coupled to the first inner base portion of the first member;
wherein the first inner base portion separates the second member from the skin, the first inner base portion extending underneath the second inner member, the first inner base portion being coupled to the second member along a second bonding surface;
wherein the first inner base portion is larger than the second inner base portion;
wherein only the first inner base portion is in contact with the skin;
wherein the panel is coupled to the first leg portion and the second leg portion; and
wherein the first member and the second member are approximately “L” shaped.
11. The joint system according to claim 10 , wherein the first member and the second member are coupled to the skin with adhesive.
12. The joint system according to claim 10 , wherein the first member and the second member are coupled to the skin with at least one fastener.
13. The joint system according to claim 10 , wherein the panel is coupled to the first leg portion and the second leg portion with an adhesive.
14. The joint system according to claim 10 , wherein the panel is coupled to the first leg portion and the second leg portion with at least one fastener.
15. The joint system according to claim 10 , wherein at least one of the first inner base portion, and the second inner base portion is tapered.
