Abstract
Honeycomb cores for use in aerospace applications include two honeycomb core sections operably joined at a splice joint, the splice joint defined by a foam adhesive that is sandwiched between a sheet of film adhesive. Methods of assembling honeycomb cores also are disclosed herein.
Claims20
A honeycomb core for use in an aerospace application, the honeycomb core comprising:
- a first honeycomb core section defining a plurality of first cells, wherein the first honeycomb core section has (i) a first edge generally aligned with longitudinal axes of the first cells, and (ii) a first side generally perpendicular to the longitudinal axes of the first cells;
- a second honeycomb core section defining a plurality of second cells, wherein the second honeycomb core section has (i) a second edge generally aligned with longitudinal axes of the second cells and positioned adjacent to and spaced apart from the first edge, and (ii) a second side generally perpendicular to the longitudinal axes of the second cells and generally aligned with the first side;
- a sheet of film adhesive including a first portion extending partially along the first side, a second portion extending along the first edge, a third portion extending along the second edge, and a fourth portion extending partially along the second side;
- and
- a foam adhesive positioned between the second portion and the third portion of the sheet of film adhesive.
