Things To Know About Glass Fiber Reinforced Polymer

By Lelia Hall


As of today, a wide array of fiber options are available in the industry. Each of them is useful for the reinforcement of polymer composites. Basically, one of the reasons of corrosion of the reinforcing steel metals is due to the failure of structures made of concrete. This phenomenon cannot be avoided that most concrete composition will crack creating an avenue for chlorides and other substances to oxidize the steel bars. Fiberglass is one of the popular reinforced plastics used for reinforcement fibers particularly for glass fibers.

It is a lightweight material and used for many products. It is an immensely versatile material because to its lightweight, weather resistant finish, inherent strength and variety of surface textures. Actually, glass fiber reinforced polymer is a proven and successful alternative reinforcing spectrum of authoritative consensus design guides, construction standards, materials, test methods, product procurement specs and qualification of procedures available to the designer.

This is to ensure that designers and owners are safely and commercially implement the reinforcement in different types of structures. Fiberglass is a glass that has been used into different forms of fibers. It is not as strong or stiff as the carbon types, but has characteristics that make it advisable in many applications. It is not also non conductive and generally invisible to all types of transmissions. This makes it an ideal choice when dealing with broadcast or electrical applications.

The mechanical behaviors and properties of fiber reinforced polymers including composites with carbon and glass fibers, versus metal reinforcing must be understood before undertaking the design of structures with the use of these reinforcements. These systems are increasingly acceptable alternative to steel reinforcement for reinforced concrete structures.

The advantages of these systems over steel reinforcement is its flexibility to corrosion. Masonry structures may also benefit from these systems. They are useful to strengthen the structures that is specified by structural engineers in both private and public industries. Using glass fibers are the primary reinforcing fiber in all FRPs.

An essential factor to consider when choosing the type of reinforced composite for structural applications is to understand the limitation of the fibers to resist long term loading. Cyclic and continuous loading in a fiber polymer in excess of its ability to resist loads may persuade fatigue failure, long term deflection and creep rupture in the structural element.

Most of these advantages may also include the high strength, corrosion resistant and lightweight, as well as low thermal conductivity, stable and non conductive. It is also electromagnetically transparent, impact resistant and low life cycle costs. However, it has higher initial costs than steel reinforcements.

FRPs used as structural augmentation are widely used in variety of applications. They are used in bridges, roads, tunnels, slopes and marine environments. An internal augmentation has a particular advantage in tunnel walls, where steel reinforcement would damage the face of the tunnel boring machine.

Knowing all of those things about the system is somewhat critical to the success of your structural projects. This way, you will be aware on things that would affect the whole process of your project. Once you understand the materials and the procedures, it would be easier for the project to be done successfully.
