Abstract
A method of assembling a composite panel includes disposing a pliable matrix material between a first side of a ceramic core structure and a ceramic matrix composite face sheet, wherein the ceramic core structure comprises a plurality of hollow cells defined by a plurality of walls extending from the first side of the ceramic core structure to a second side of the ceramic core structure opposite the first side; and densifying the pliable matrix material to bond the pliable matrix material with the ceramic core structure and the ceramic matrix composite face sheet.
Claims18
A method of assembling a composite panel, the method comprising:
- disposing a pliable matrix material tape between a first side of a ceramic core structure and a ceramic matrix composite face sheet, wherein the ceramic core structure comprises a plurality of hollow cells defined by a plurality of walls extending from the first side of the ceramic core structure to a second side of the ceramic core structure opposite the first side, and wherein the pliable matrix material tape comprises chopped fibers;
- and
- densifying the pliable matrix material tape to bond the pliable matrix material tape with the ceramic core structure and the ceramic matrix composite face sheet.
A composite panel comprising:
- a ceramic core structure comprising a plurality of hollow cells defined by a plurality of walls extending from a first side of the ceramic core structure to a second side of the ceramic core structure, the second side opposite the first side;
- a ceramic matrix composite face sheet disposed at the first side of the ceramic core structure;
- and
- a matrix material tape that is densified and bonded with both the ceramic core structure and the ceramic matrix composite face sheet, wherein the matrix material tape comprises chopped fibers.
A composite panel comprising:
- an additively-manufactured ceramic core structure comprising a plurality of hollow cells defined by a plurality of walls extending from a top face to a bottom face;
- a ceramic matrix composite face sheet;
- and
- a conformal interface layer tape bonding the top face of the additively-manufactured ceramic core structure to the ceramic matrix composite face sheet, wherein the conformal interface layer tape comprises chopped fibers.
