Abstract
A casing for a gas turbine engine, including: a containment fabric layer wrapped around a structural shell; and a bi-material shell located around the containment fabric layer, the bi-material shell formed from a plurality of bi-material shell segments, each of the plurality of bi-material shell segments include an inner layer and an outer layer, the outer layer comprises a plurality of individual segments that form the outer layer and a plurality of embedded fuse lines defined by the plurality of individual segments of the outer layer, wherein an overall structure of the bi-material shell does not impede a rapid expansion of the containment fabric layer.
