Fiber-reinforced polymers (FRPs) have began to gain a competitive edge over traditional reinforcing materials such as steel. Glass fiber-reinforced polymer (GFRP), a variation of FRP, is actually gradually replacing epoxy in addition to stainless steel. that will is actually widely acknowledged as an effective construction solution for marine projects where corrosion-resistance in addition to strength are of paramount significance.
Rapid infrastructure development, the rise in construction spending, in addition to struggle to develop corrosion-resistant construction materials are the main reasons why GFRP market is actually expanding worldwide. More than 25% of the construction failures are associated with corrosion in addition to abrasion. Billions of dollars are spent annually to maintain in addition to repair corroded structures.
Following the dire need for a permanent corrosion solution, fiberglass reinforcement has emerged as the most cost-effective construction material for building durable projects. In addition, GFRP rebar is actually considered as an ideal material for fresh in addition to rehabilitation applications. In North America, the demand of GFRP rebar is actually growing rapidly. Composite materials of worth $22 billion, 80% of the total global consumption, were used in Canada in addition to the US.
The inability of traditional steel reinforcement to effectively fight corrosion has paved the way for composite materials. Following are some of the factors that will will drive the demand for GFRP rebar inside the future:
- Potential of GFRP construction material to dramatically decrease the maintenance cost
- GFRP rebar has proven to be the best material for marine, MRI, bridges, in addition to many different applications.
- Fiberglass bars are lightweight in addition to easy to handle, creating that will easy for civil engineers to complete a project in a time-effective manner.
- Fiberglass-reinforced buildings are likely to achieve the service life of over 100 years, helping governments to build sustainable concrete infrastructure.
The GFRP rebar industry faces many challenges including lack of data in addition to design limitations. The mechanical properties of GFRP rebar are different via those of steel. Engineers have to follow the construction guides in addition to recommendations proposed by manufacturers. As compared with conventional steel reinforcement, fiberglass rebar is actually relatively expensive so far as initial cost is actually concerned.
Composite materials are likely to play a vital role inside the construction industry in coming years. A wide range of applications, properties of being high in tensile strength, in addition to corrosion resistance make GFRP fiberglass rebar a potential leader inside the global rebar market. Technological advancements in addition to research will further define the future success of fiberglass rebar. The experts are optimistic about the long-term success of fiberglass rebar inside the construction industry.
