Developing Performance and Operating Requirements for Energy Attenuation (EA) Roof Liners for all U.S. Army Military Vehicles

by Julie Klima


The primary focus of this effort is to evaluate the roof liner technology’s ability to reduce the head injury criteria (HIC) and head acceleration to mitigate vertical impact related injures to mounted crew injures which may occur during top and bottom threat events. In an effort to reduce the likelihood of head injury during top and bottom threat attacks, an adequate roof liner is needed to reduce the force exerted on the solider. The roof liners were able to pass all system level tests. The successful system level testing confirmed the blast mat technology’s TRL-6 recommendation.
