Secrets Behind The 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.

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.

Pultrusion happens when several minerals were burnt to hot furnace to achieve the creation of fiberglass. It is a composite material of reinforced with fiber and polymer matrix. It is light, reliable, corrosion resistant, and many more. This is commonly used in aerospace, construction, marine, etc. There are two ways in how the manufacture of fiber reinforcement is done. Here are the following.

Two Dimensional Fiber Reinforced Polymer. It is a laminated structure where the materials are aligned to x and y directions only. The z direction is not included. Labor and price are affected in this.

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.

In addition, there are ways to do the textile processing. It includes weaving, knitting, stitching and braiding. Unfortunately, GFRP is not just as great as it seem. It also has its own limits. In spite of its strength and other features, it has a weak point. It is also subject to weakness depending on the amount of correct mixture when it was created. Its liability is depending on the quality of the way it was made.

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.
