FRP or Fibre Reinforced Plastic is a polymer which is made by reinforcing it with fibre. This plastic is also known as a fibre-reinforced polymer. This type of material falls under the category of composite materials. Composite materials are those materials which are made up of one or more materials by dispersing their particles and forming a continuous network around them. Fibre-reinforced plastic is somewhat different from the constructional materials which are traditionally utilized such as Aluminium and Steel. Therefore, the properties of these materials are different from other materials. The original plastic material which is used without the reinforcement of fibre is known as the binding agent or matrix. This original plastic material is tough but as compared to reinforced plastic is very weak. This plastic is made stronger by reinforcing it with fibre.
There are two processes which are used to develop a polymer. These two processes are step-growth polymerization and addition polymerization. Fibre-reinforced plastic is formed when several homogenous materials of different properties bond together to form a final product which has all the desired material and mechanical properties. This type of plastic falls under the category where the enhancement of the mechanical strength and elasticity of the plastics is made through the bonding of fibre materials.
The formation of most of these plastics is made possible through different moulding processes where the utilization of a mould or a tool assists to place the fibre pre-form. After this process, the dry fibres are wet out with resins and then, curing takes place. During this process, the fibre and matrix take the shape of the mould. During this phase, heat and pressure are applied sometimes
Types of FRP:
There are three types of FRPs which are described below:
Glass Fibre-reinforced Polymer:
This type of FRP is made by blending limestone, silica sand, folic acid, and other ingredients in small quantity. To prepare this FRP, this mixture is heated at about 1260°C. These FRPs have high electrical insulating properties, high mechanical properties, and low susceptibility to moisture.
Carbon Fibre-reinforced Polymer:
The elasticity of these carbon FRPs is very high. These FRPs do not absorb water and resist many chemical solutions. They endure weariness amazingly and there is no sign of any corrosion or relaxation in these carbon fibre-reinforced polymers.
Aramid Fibre-reinforced Polymer:
The full form for Aramid is aromatic polyamide. These FRPs have an ultimate elongation of about 1.5-5% based on the quality of the material. These materials have high fracture energy and this is the reason they are mainly utilized for bullet-proof garments and helmets. They are highly sensitive to moisture, high temperatures, and ultraviolet radiations. Thus, these are not mostly utilized in civil engineering applications.
Properties of FRP:
There are numerous properties of FRP which are very useful for everyone such as:
The foremost important property of FRP is its inherent property of corrosion resistance
Another important property of this plastic is its low weight-to-strength ratio, which makes it very easy to install
High strength is another great property of this plastic because of which it is used in missiles and many other apparatus
This fibre-reinforced plastic is also very economical
This plastic is also a great product to use because of its flexibility
Applications of FRP:
FRP is one of the widely used products in most of the items because of their unique properties. Some of the applications of FRPs are described below:
Carbon FRPs are utilized in the applications of prestressed concrete
CFRPs are also utilized in underwater piping and structural fragments of the platform of offshore
FRPs are also used to manufacture various stairways and walkways
High-performance hybrid structures are also manufactured with FRPs
There is also usage of FRPs in seismic retrofitting
These are also utilized in the development of special structures which require electrical neutrality
