An anonymous reader writes: U.S. army engineers are developing a new blast-proof wallpaper prototype that they claim could help protect soldiers from the impact of an explosion and flying debris. The lightweight adhesive fabric is lined with ballistic Kevlar fibers embedded in flexible polymer film. Nick Boone, a research mechanical engineer at the U.S. Army Corps of Engineers, said that the rolls of paper could be easily transported by military troops and used to quickly line the walls in temporary buildings. Without the wallpaper, a wall that is hit will “rubblize,” said Boone, hurling shards of rock and mortar at the soldiers inside. However when the blast occurs with the wallpaper installed, he explained that the fabric acts as a “catcher's net,” and is able to contain the flying rubble and prevent debris from injuring soldiers.
