SANDWICH PANEL JOINTS AND METHODS FOR JOINING SANDWICH PANELS

摘要

Joints for joining panels (60, 62) together, such as for joining honeycomb sandwich panels used in aerospace applications, and methods of joining said panels are disclosed. In some examples of disclosed joints, a first panel and a second panel can be joined together to form a joint. The first panel (60) can be a flat panel that includes a rabbet (80) formed along a first longitudinal edge, and the second panel (62) can be a curved panel that includes a notch (86) formed along a second longitudinal edge. In forming the joint, a portion of the rabbet (80) can be positioned within the notch (86), and the flat panel (60) and curved panel (62) can be oriented at a non-parallel and non-perpendicular angle to one another. Adhesive (99) is applied along the rabbet (80) and/or the notch (86) in order to secure the joint.

主权项

1. A joint, comprising:
a first panel having a first honeycomb core having a first thickness, the first honeycomb core being sandwiched between a first skin and a second skin, wherein a first longitudinal edge of the first panel has a rabbet formed along a majority of an entire length of the first longitudinal edge; a second panel having a second honeycomb core having a second thickness, the second honeycomb core being sandwiched between a third skin and a fourth skin, wherein a second longitudinal edge of the second panel has a notch formed along a majority of an entire length of the second longitudinal edge, wherein at least a portion of the rabbet is positioned within the notch such that the first longitudinal edge and the second longitudinal edge are aligned to form the joint; and an adhesive applied to at least one of the first longitudinal edge and the second longitudinal edge, wherein the second skin of the first panel and the third skin of the second panel are oriented at a joint angle with respect to one another, the joint angle being non-parallel and non-perpendicular.
