The Truth About GFRP Reinforcement

By Ericka Marsh


Look around you in the city. Try to examine the structures. You can see many buildings under construction. They are soon to rise. Beneath the beautiful tall buildings are the necessary equipments and materials needed to make it according to what the architects and engineers planned. There are a lot of details about it that you do not know yet.

In the beginning of the construction, there are certain needed foundations to be placed. Specific measures are required to meet the quality of it. Every building needs a framework. A Glass Fiber Reinforced Polymer, GFRP reinforcement, is part of its brace. This is to strengthen superstructure components of big projects. It is made up of composite materials.

It is a sturdy lightweight object used in numerous purposes. Its contents is based primarily on carbon fiber. It is less brittle and inexpensive. It has great amount of strength that surpasses the capacity of any metal. It is also very uncomplicated to mold into the form you desire.

Years before, Owens Games Slayter accidentally directed compressed air full jet at a stream of hot glass. He then discovered that it produced fibers. That its strength capability is astounding. He called its process, pultrusion.

In pultrusion, many minerals were exposed to hot furnace to form the fiberglass. It is a composite material made of polymer matrix reinforced with fibers. It is very light, durable, rust resistant and sturdy. They are commonly used in aerospace, automotive, marine, construction and many others. The manufacture of this is done in two ways. These ways differ in some way. Take a look at their difference.

Two Dimensional Fiber Reinforced Polymer. In this laminated structure, only the x and y directions are aligned. There is no alignment in the z direction. Through this, job and charges are increased.

Three Dimensional Fibre Reinforced Polymer. It is composed of materials that incorporate the fibre structures in all directions that in includes x, y and z. This was created to minimize the cost and labor.

There are also several ways of textile processing are done in weaving, knitting, braiding and stitching. However, GFRPs have its own advantages and limitations. Though they allow the alignment of the glass fibers of thermoplastics that helps increase heat resistance and strength, it is also its limitation. It always have a weak spot that is where laborers put the hinges. And it is not a guarantee that having a its content is strong enough to hold any weight because it always depend on the amount of components being mixed during the process of it.

Most construction firms use them because there are countless benefits when you use it. It is also anticipated by the experts which they allowed it to be just a reinforcement to the foundation. In total, it contributed in creating the superstructures both attractive and strong. Around the world, both in business and at home used daily. You can even see them everywhere. They are sold mostly in hardware stores. You can even buy one for your home. It is very useful and durable even for daily use. Now let us appreciate the little details we discovered about the fiber glass, GFRP. They greatly added quality to our superstructures.
