Fibrous and composite materials for blast protection of structural elements—A state-of-the-art review

Abstract

Contemporary world is facing numerous bomb explosion attacks on public and civil buildings causing huge loss of property and human lives. As a consequence, the society needs more safety and protection for the existing structures against blast loads. Among the various strategies, one effective way to enhance the blast resistance of reinforced concrete and masonry structures is through retrofitting using various types and forms of fibrous and composite materials. This work presents an up to date review of available literature and publications on the fibrous and composite materials utilized for blast protection of structural elements and highlights the lacking areas where further research is required.

Development and characterization of novel auxetic structures based on re-entrant hexagon design produced from braided composites

“…[1e4]. Recently, composites have been applied widely in civil engineering applications to replace conventional materials (concrete and steel) or ceramic based composites [1]. Composites are introduced into structural elements to improve their flexural resistance, shear strength, confinement, bending property, etc.…”

“…Composites are introduced into structural elements to improve their flexural resistance, shear strength, confinement, bending property, etc. [1]. Nowadays, research is being carried out to use composite materials in structural elements to improve their resistance against earthquake, blast or impact loads caused by explosions [5].…”

Performances, challenges and opportunities in strengthening reinforced concrete structures by using FRPs – A state-of-the-art review

“…In the modern world, blasts occur in different places due to terror attacks, nuclear explosions or accidental explosions. Ensuring a sufficient standoff distance is very effective way of protecting structures from blasts [72,73].…”

Textiles and Fabrics for Enhanced Structural Glass Facades: Potentials and Challenges

“…Due to the relatively high vulnerability of glass windows and facades, one of the recent applications of textiles in existing structures can take the form of special curtains, aimed at protecting the occupants in the case of extreme loads, such as impacts and explosions ( Figure 14 and [85]), but also fire [86].
