Abstract
Composite containment casing including a body having an interior, an abradable system integrally joined to the interior of the body of the containment casing wherein the abradable system comprises, a sandwich structure including a first facesheet and a second facesheet position about at least one core layer, and at least one abradable layer applied to the sandwich structure wherein the at least one core layer comprises any of a cell configuration, a columnar configuration, or a truss configuration and wherein the sandwich structure is strong radially and weak circumferentially.

A composite containment casing comprising:
- a body having an interior;
- an abradable system integrally joined to the interior of the body of the containment casing wherein the abradable system comprises:
- a sandwich structure including:
- a first facesheet and a second facesheet position about at least one core layer;
- and
- at least one abradable layer applied to the sandwich structure
- wherein the at least one core layer comprises any of a cell configuration, a columnar configuration, or a truss configuration and wherein the sandwich structure is strong radially and weak circumferentially.
A composite fan casing for a gas turbine engine fan assembly comprising:
- a body having an interior;
- an abradable system integrally joined to the interior of the body of the fan casing wherein the abradable system comprises:
- a sandwich structure including:
- a first facesheet and a second facesheet position about at least one core layer;
- and
- at least one abradable layer applied to the sandwich structure
- wherein the at least one core layer comprises any of a cell configuration, a columnar configuration, or a truss configuration and wherein the sandwich structure is strong radially and weak circumferentially.
A composite fan casing for a gas turbine engine fan assembly comprising:
- a body having an interior;
- an abradable system integrally joined to the interior of the body of the fan casing wherein the abradable system comprises:
- a sandwich structure comprising a material selected from the group consisting of carbon fibers, graphite fibers, glass fibers, ceramic fibers, aramid polymer fibers, and combinations thereof, and including:
- a first facesheet and a second facesheet position about a plurality of core layers;
- and
- at least one abradable layer comprising a low-density syntactic film epoxy applied to the sandwich structure
- wherein the at least one core layer comprises any of a cell configuration, a columnar configuration, or a truss configuration, and wherein the sandwich structure is strong radially and weak circumferentially.
