Application of High Energy Absorbing Materials for Blast Protection

Abstract

In the current century, building protection is very important in the face of terrorist attacks. The old buildings in Europe are not sufficiently resilient to the loads produced by blasts. We still do not fully understand the effects of different explosives on buildings and human bodies. [1–3] Computing blast loads are different from that of traditional loads and the material selection rules for this type of impact load are diverse. Historical and old buildings cannot be protected simply by new walls and fences. New ways need to be found to improve a building’s resistance to the effects of a blast. It requires sufficiently thin yet strong retrofitted materials in order to reinforce a building’s walls [4–6].

Meta-Material Layout for the Blast Protection of Above-Ground Steel Pipes

“…The main challenges of the effective blast protection of buildings were identified [66], and special guidelines for the design of blast-resistant buildings [67,68] were suggested. Advanced material solutions were developed for this goal, including fiber-reinforced polymers (FRPs) and composite materials for the blast protection of structural elements [69][70][71], retrofitting materials for enhanced blast performance [72] and high energy-absorbing materials [73]. Other advanced materials can be considered, including ultra-high-performance concrete under impact loading [74][75][76], hybrid-reinforced concrete [77] and reinforced concrete beams strengthened with carbon fiber-reinforced polymer [78].…”
