Fan case ice liner for turbofan engine

An ice liner assembly for a fan containment case assembly, the ice liner assembly comprising:

• a plurality of arcuate panels arranged end to end to form a cylinder with a plurality of splice joints, each splice joint formed by an end of one panel abutting an end of another panel;
• a plurality of splice support cores, each splice support core engaging and being disposed radially outside of one of the splice joints;
• a plurality of standard support cores, each standard support core being disposed radially outside one of the arcuate panels and between two of the splice support cores;
• the splice support cores including a molded polymer selected from the group consisting of polyetherimide (PEI), polyimide, polyether ether ketone (PEEK), polycarbonate (PC), polyether ketone ketone (PEKK), polysulfone, Nylon, polyphenylsulfide, reinforced polyetherimide, reinforced polyimide, reinforced PEEK, reinforced PC, reinforced PEKK, reinforced polysulfone, reinforced Nylon, reinforced polyphenylsulfide, and combinations thereof.

A fan containment case assembly, comprising:

• a cylindrical outer case;
• a front cylindrical liner disposed inside the outer case;
• an ice liner assembly disposed inside the outer case;
• an abradable strip liner disposed inside the outer case and between the front liner and the ice liner;
• a rear liner disposed inside the outer case and opposite the ice liner from the abradable strip liner;
• the ice liner assembly including a plurality of arcuate panels arranged end to end to form a cylinder with a plurality of splice joints, each splice joint formed by an end of one panel abutting an end of another panel;
• the ice liner assembly further including a plurality of splice support cores, each splice support core engaging and being disposed radially between one of the splice joints and the outer case;
• the ice liner assembly further including a plurality of standard support cores, each standard support core being disposed radially between one of the arcuate panels and the outer case and circumferentially between two of the splice support cores;
• the splice support cores including a molded polymer selected from the group consisting of polyetherimide (PEI), polyimide, polyether ether ketone (PEEK), polycarbonate (PC), polyether ketone ketone (PEKK), polysulfone, Nylon, polyphenylsulfide, reinforced polyetherimide, reinforced polyimide, reinforced PEEK, reinforced PC, reinforced PEKK, reinforced polysulfone, reinforced Nylon, reinforced polyphenylsulfide, and combinations thereof.
