Joint member for a composite wing structure
First Claim
1. A joint system for a composite skin assembly, comprising:
- a composite skin comprising a first skin, a second skin, and a honeycomb core, disposed between the first skin and second skin, the honeycomb core and the second skin extend in a spanwise direction on the first skin, the honeycomb core having an edge disposed on the first skin, the second skin haying an edge disposed on the honeycomb core; and
a joint member comprising;
a support member having a first side and a second side;
a first flange extending laterally from the first side and having an attachment surface configured for attachment to the first skin; and
a second flange extending laterally from the second side and having an attachment surface configured for attachment to the second skin;
wherein the attachment surface of the first flange is coupled to the first skin and the attachment surface of the second flange is coupled to the second skin;
wherein the joint member secures the second skin to the first skin.

Abstract
In one aspect, there is a joint member for a composite having a laminate layer including a support member having a first side and a second side; a first flange extending laterally from the first side and having an attachment surface for attachment to a structure; and a second flange extending laterally from the second side and having an attachment surface configured for attachment to the laminate layer. The joint member is configured to provide a load path from the first flange to the second flange. In an embodiment, a joint system for a composite system includes a joint member attached to a first skin and a second skin. In still another embodiment, a joint system for a rib assembly includes a joint member attached to a rib web and rib post.
