Abstract
A honeycomb structure includes at least two corrugated strips having major flat surfaces extending angularly between opposed strip edges. The strips are offset relative to each other and joined together to define a series of cells extending between the strip edges along axes which are oriented at an angle other than normal to the strip edges. Each of the major flat surfaces includes a central depressed portion forming a matching sub-flat surface which is parallel to and connected to the major flat surface by sidewalls which may be substantially perpendicular to the major flat surface. Abutting undepressed portions of the major flat surfaces of adjacent strips and abutting sub-flat surfaces of adjacent strips are joined together so that the strips form a series of I-beams disposed one to a cell.
Claims19
A honeycomb structure comprising
- a pair of face sheets, and
- at least two corrugated strips arranged between the face sheets and having opposed edges joined to the face sheets, the strips being corrugated to form multiple major flat surfaces extending angularly between the opposed strip edges, the strips being offset relative to each other to define a series of cells extending between the face sheets along axes which are oriented at an angle other than normal to the face sheets, each of the major flat surfaces having a central depressed portion forming a matching sub-flat surface which is parallel to and connected to the major flat surface by sidewalls, abutting undepressed portions of the major flat surfaces of adjacent strips and abutting sub-flat surfaces of adjacent strips being joined together, the strips thereby forming a series of I-beams disposed one to a cell.
A honeycomb structure comprising
- a pair of face sheets, at least a first of which defines a three-dimensional surface, and
- at least two corrugated strips arranged between the
- face sheets and having opposed edges joined to the face sheets, the strips being corrugated to form multiple major flat surfaces extending angularly between the opposed strip edges, the strips being offset relative to each other to define a series of cells extending between the face sheets along axes which are oriented at a substantially consistent angle other than normal to the face sheets, each of the major flat surfaces having a central depressed portion forming a matching sub-flat surface which is parallel to and connected to the major flat surface by sidewalls, abutting undepressed portions of the major flat surfaces of adjacent strips and abutting sub-flat surfaces of adjacent strips being joined together, the strips thereby forming a series of I-beams disposed one to a cell.
A honeycomb structure comprising
- a pair of cylindrical face sheets arranged to define an annular space therebetween, and
- at least two corrugated strips arranged between the face sheets in the annular space and having opposed edges joined to the face sheets, the strips being corrugated to form multiple major flat surfaces extending angularly between the opposed strip edges and being offset relative to each other to define a series of cells extending between the face sheets along axes which are oriented at the face sheets at a substantially consistent angle all around the cylinder, each of the major flat surfaces having a central depressed portion forming a matching sub-flat surface which is parallel to and connected to the major flat surface by sidewalls, abutting undepressed portions of the major flat surfaces of adjacent strips and abutting sub-flat surfaces of adjacent strips being joined together, the strips thereby forming a series of I-beams disposed one to a cell, and
- wherein the corrugated strips are arranged between the parallel face sheets so that all of the cells extend along axes which are oriented at the face sheets at a substantially consistent angle other than normal to the face sheets.
A substantially synclastic honeycomb structure comprising at least two corrugated strips having major flat surfaces extending angularly between opposed strip edges, the strips being offset relative to each other and joined together to define a series of cells extending between the strip edges along axes which are oriented at an angle other than normal to the strip edges, each of the major flat surfaces having a central depressed portion forming a matching sub-flat surface which is parallel to and connected to the major flat surface by sidewalls, abutting undepressed portions of the major flat surfaces of adjacent strips and abutting sub-flat surfaces of adjacent strips being joined together, the strips thereby forming a series of I-beams disposed one to a cell.
A method for making a honeycomb structure comprising the steps of
- providing a plurality of corrugated strips having major flat surfaces extending angularly between opposed strip edges,
- arranging the strips relative to each other to define a series of cells extending between the strip edges along axes which are oriented at an angle other than normal to the strip edges, and
- joining abutting major flat surfaces of adjacent strips together to form a honeycomb structure.
