Ballistic materials for enhanced energy absorption and gas turbine fan casings including the same

摘要

Ballistic materials for enhanced energy absorption and fan casings (26) for turbine engines including the same are provided. A hybrid ballistic material (10b) comprises a first ballistic fabric (18) and at least one individual member (12)woven through at least a portion of the first ballistic fabric (18). The fan casing (26) comprises at least one layer of a first crushable material (48)circumscribing a fan containment case (36). A ballistic material comprising a net-like ballistic material (10a) or the hybrid ballistic material (10b) circumscribes the at least one layer of the first crushable material (48). At least one layer of a second crushable material (54) may circumscribe the ballistic material (10a,10b) with the ballistic material (10a,10b) disposed between the at least one layer of the first and second crushable materials (48, 54). A containment covering (62) is an outermost layer of the fan casing (26).
