Secrets Behind The GFRP Reinforcement

By Ericka Marsh


Look at your surroundings. Observe them one by one very carefully. Take time to scrutinize the things around you. Identify them one by one. If you see buildings, survey its structure. Surely, all the little details of how it is built is a big question mark in your mind. How architects designed them. How amazing that engineers made it possible to become a reality. There are a lot of fascinating facts that you are yet to know.

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 known to be lightweight and useful. It is based on majorly on carbon fiber. It is resilient and affordable. Its amazing solid quality outmatch those that of many metals. It is simple to mold.

Many years before, an accidental discovery of Owens Games Slayter happened. It was not in his intention to invent something extraordinary. Until one day, a jet full of compressed air went straight to a stream of molten glass. He was able to discover that it became hard enough to withhold any pressure or weight. He then tried to manufacture more of it then called the process as pultrusion.

The process of pultrusion is burning of many metals in hot furnace to create fiberglass. It is a widely known composite material of fiber being reinforced with polymer matrix. It is very light, flexible and resistant to rust, etc. This usually used in aerospace, marine, construction, etc. Aside from this, it has two ways how it is manufactured as reinforcing fiber. Let us learn how they differ from each other.

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 Fiber Reinforced Polymer. An incorporation of fibers are aligning in all directions from x, y and z. This decreases 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.

Majority of the construction firms used fiberglass to reinforce the durability of the framework of the foundation of the structure. Even if this weakness had been known to the employees assigned in construction sites, they still use it most of the time. This had given more to complete the beauty of the superstructures and their dependability. It is also used in other places like at household, offices, etc. You can even purchase them at hardware stores near your place. It is sufficient to appreciate the tiny details we just learned. They progress the condition of our structure.
