Abstract

The present invention relates to a fan containment case assembly (62) for a turbofan gas turbine engine, wherein the case assembly (62) includes an outer case (70) extending about an axis (A), and a thermally conforming liner assembly (78) radially inward of the outer case (70). The liner assembly (78) has a shell (82), a wrap (108) radially outward of the shell (82), and a ballistic liner (74) between the outer case (70) and the wrap (108). The wrap (108) has a first fiber construction, and the ballistic liner (74) has a second fiber construction that differs from the first fiber construction in stiffness. The wrap (108) is made of non-impregnated fibers, preferably aramid fibers, reducing overall weight. The ballistic liner (74) may be made of metal or of resin impregnated fibers. For mainting circumferential position of the liner assembly (78), ribs (114) cooperate with corresponding torque blocks (112).
