Abstract
The invention is directed towards a film-based polymeric cellular matrix, methods for making the polymeric cellular matrix, articles of manufacture incorporating the polymeric matrix and methods for making articles of manufacture. The polymeric cellular matrix is characterized as a plurality of generally identical cells (open-ended geometric prisms) arranged to form a repeating geometric form. The matrix is particularly suited for use as a core between two panels.
Claims21
A collapsible polymeric matrix of single-walled cells comprising:
- a first row of film-based, open-ended hollow prisms, each prism having a perimeter enclosing wall that includes a plurality of wall segments, the first row having at least a first type of prism alternating with a second type of prism to form a repeating sequence of prisms wherein each prism in the row shares a common enclosing wall segment with a directly adjacent prism;
- and
- a second row of film-based, open-ended hollow prisms, each prism having a perimeter enclosing wall that includes a plurality of wall segments, the second row having at least the first type of prism alternating with the second type of prism to form a repeating sequence of prisms, wherein each prism in the row shares a common enclosing wall segment with a directly adjacent prism, wherein each row has a generally constant upper and lower boundary and wherein no row overlaps another row, when the matrix is in an expanded state, wherein each wall segment of each prism defines an orifice to establish fluid communication with an adjacent prism.
