“…Some common retrofit techniques have been introduced in previous work which focused on the practical aspects of retrofit techniques used for the blast protection of buildings. it presents the summary of various retrofit techniques [12,14]. in the case of the introduced extraordinary dynamic loads, we needed to select or innovate a high kinetic energy absorbing material.…”

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].

“…The most important part of composite design is the determination of loads and, therefore, the determination of stresses [10][11][12][13][14]. on the basis of the determined loads, we can select the matrix and reinforcing materials and we can analysis their adequacy.…”

The goal of this work was to invent a high energy absorbing composite material. This composite needs to be able to attach on the building's surfaces and increase blast-resistance. In this innovation, the test samples were reinforced with aramidfiber, glass fiber and carbon fiber and tested by Charpy pendulum impact testing machine. During the tests, the aramid and glass fiber reinforced composites showed good resistance and high energy absorption against impact load.

Unfortunately, people can’t live in peace in this century: many wars and terrorist attacks have been witnessed even within the last year. In the case of such attacks, both the people and the civil infrastructure is in danger [1-3]. The modern age (infrastructure) provides electrical networks and communication networks for the citizens. Without electricity and/or communications (e.g. the internet), urban life is paralysed. Explosions create heat and shock waves and their effects can potentially damage the wall and cables of a building as changes in the material structure occur. In this article, the authors introduce a blast load effect testing method in an empirical way. The metal microstructure deformation level is measurable by changes in resistance, because resistance is a physical property which depends on the crystal structure of the metal.
