FRP Composites For The Future of Construction

Although the potential of fiber reinforced polymer (FRP) was realized more than five decades ago, obstacles such as high upfront costs, limited practical data and vulnerability to static fatigue, etc., have continued to emerge. limit their use as a sustainable building material. The construction industry, however, has adopted advanced composite materials to solve some of its major problems such as corrosion, premature deterioration of concrete, and expensive maintenance. Over the past two decades, extensive research has led to a better understanding of FRPs in different environments.

It is very important to bring together the different aspects of composite materials, including their stability and structural characteristics, in order to clearly define the rehabilitation and new applications of FRP composites in civil engineering. Given their advantageous characteristics, FRP is already used as a high strength and corrosion-free concrete reinforcement. The electromagnetic neutrality of FRPs makes them ideal for MRI units, research laboratories and educational institutions.

Modern engineering takes sustainability and the environment seriously. We can find a number of case studies presenting the rehabilitation and design of new concrete elements with FRP. According to most studies, the main advantage of FRP materials, over traditional competitors, is long maintenance-free life. In addition, composite materials are environmentally friendly. The properties of composite materials, such as GFRP fiberglass rebar, can be customized to suit a project’s requirements.

Modernization and rehabilitation of prestressed and reinforced concrete structures using fiber-reinforced polymers are now well established techniques. The strength of externally bonded FRP composites has demonstrated many advantages including strength-to-weight ratio and ease of installation. In addition, the ease of transport and installation without heavy equipment makes FRP a promising material for rehabilitation and construction of bridges.

Manufacturing technologies for the production of advanced composites have been revolutionized by new sophisticated manufacturing techniques. These methods have allowed manufacturers to produce good quality laminates with precise fiber alignment and minimal voids.

Since World War II, the construction industry has suffered from a lack of research and investment. The early 1990s saw a severe decline in the industry in North America. The construction industry was seen as a low labor intensive technology compared to other industries. However, things have changed dramatically over the past two decades. Innovative materials and construction techniques have played a big role in transforming construction into a technology-driven industry. If you are looking for innovative building materials for your next project, you must explore and implement FRP technologies to achieve lasting results.
