FRP Products Versus Conventional Building Materials

FRP (Fibre-reinforced plastic) is an amalgamated material created from the polymer mold toughened with fibres. These strands used are normally carbon, glass, basalt or aramid. The other types of strands used are wood or asbestos. Various industries such as marine, automotive, construction and aerospace make use of these products.

This material is becoming popular, especially in the construction industries. Due to its excellent properties such as lightweight, high tensile strength and non-corrosive nature, this material has gained acceptance over the traditional materials such as steel. Following are some of the advantages of the FRP over the conventional building materials:

• This particular composite material is highly resistant to corrosion, unlike steel and other metals. This material remains unaffected by the impact of water, chemical gases and fumes. Due to this non-corrosive property, there is an extensive variation of these products that are capable of withstanding the effects of rust and chemicals.

• The FRP products are about 65 to 75% lighter than steel, yet stronger than steel. This lightweight of this material has reduced the costs associated to its transport, handling and installation.

• Due to its non-corrosive property, this composite material hardly requires maintenance, thus removing the need of maintenance costs. One only needs to take care of cleaning this material of dirt and debris. Also, being lighter than steel, this material could be lifted with ease and moved as per one's convenience.

• In comparison to steel, this advanced composite material tends to get back to its original shape after the deflection. This is possible mainly due to its advanced elastic property. Even test conducted have shown that these materials can withstand a huge amount of pressure, without displaying lasting shape deformation.

• The products made from this composite material have the highest level of resistance to slip. As per the safety standards set by OH&S, it is 50-70% safer than the other materials in terms of slip resistance. This percentage is crucial for safety conscious workplaces such as factories, oilrigs and so on.

• This material is perfect for using in sensitive environments mainly due to its intent ability to disperse static electricity. This property is very crucial while working in underground locations and gaseous environment where there are chances of sparks rising from the colliding of metals.

• The FRP products are capable of withstanding the intense amount of heat for prolonged periods. This heat resistance varies according to the type of fibre strands used in the crafting of these products.

These properties truly make the FRP products popular than the conventional building materials. These materials are becoming the best choice for engineers and constructors.

Have Strong Fibre-Reinforced Profiles With Pultrusions

FRP materials are in great demand in the current market scenario. A popular method used in the manufacture of fibre-reinforced plastics is pultrusions. This is one of the traditional methods used for producing FRP materials. It is a conventional processing technique used in many industries to a great extent. Pultrusion consists of two words - 'extrusion' and 'pull'. Extrusion is pushing materials like aluminum while pultrusion is pulling materials like resin and fibreglass.

Historical Background of the Technique:

W. Brant Goldsworthy, the "father of composites" had developed this process in the year 1954. This pioneer of fibre composite technology had provided an elaborate description of this relevant process to the professional circles in United States. This process is ideal for making profiles of hammer handles, fishing rods, vaulting poles, ski poles and so on. Corresponding to this, Ernst Kuhne too developed the method of pultrusion in 1950. He successfully produced the first product by employing this technology without external intrusion.

Other countries also started using the technique for creating pultruded profiles featuring the strength of glass fibre. In this regard, vertical and horizontal approach came into existence. With the help of vertical approach, industries developed a huge array of profile cross-sections. However, the entire process has undergone a lot of diversification in the last few years.

A Quick Review of Pultrusion Method:

The whole process begins with creels or racks that hold fiber mat rolls or doffs of fibre roving. Usually, fibreglass serves the purpose of reinforcement, but aramid, carbon or their mixture can very well serve the purpose. After pulling out the raw fibre from the racks, they pass through a resin impregnation system or resin bath. Some pultrusion systems even inject resin straight in the die. Resin, in its raw form, acts as thermosetting resin and might at times combined with pigments, catalysts and fillers.

Make sure that the resin mixture completely saturates the fibre filaments so that fibre reinforcement is totally wet. When raw resin comes out of resin impregnation system, this material passes through line of customized tooling that assists in organizing and arranging the fibres in their proper shapes. The extra resins get squeezed out. This step of tooling is 'pre-former'. Surface veils and continued strand mat added to the product in this tooling step boost up surface finishing and structure.

After removal of extra resin and organization of impregnated fibre, it passes through hot steel die. Now, the profile that comes out of the die is the pultruded FRP or Fiber Reinforced Polymer. These final products, so obtained from pultrusions, get ready for distribution in the market.
