FRP (GRP) is being increasingly used for corrosion Resistant application as it offers better corrosion resistance to specific environment and temperature.
We have over 40 of years experienced staff in fibre glass. Products such as FRP pipes, military shelters, automobile parts, large tanks have been developed by our experienced staff.
Benifits of reinforced plastics
Fibre-reinforced plastic is a composite material, made of a polymer matrix reinforced with glass fibres. Carbon, basalt, aramid, paper, wood or asbestos can be used in different situations. Polymer is usually an polyester, epoxy, thermosetting plastic, vinylester, phenol formaldehyde resins. FRPs are commonly used in the aerospace, automotive, marine, construction industries and military.
FRP allows fibres of plastics to suit specific designs. The specific orientation of reinforcing fibres can increase the strength and resists deformation. Glass fiber is strongest and most resistive to deforming forces when the polymers fibres are parallel to the force being exerted, and are weakest when the fibres are perpendicular. This can be an advantage or a limitation depending on the context of use. Perpendicular fibres can be used for natural hinges and connections, but can also lead to failure of the material when fibre orientation is not parallel to expected forces. When forces are exerted perpendicular to fibres the strength and the elasticity of the polymer is less than the matrix alone. In cast resin components made of frp, the orientation of fibres can be 2D and 3D weaves. This means forces perpendicular to one orientation, parallel to another orientation; eliminating weak spots.
FRP is used for high strength or modulus of elasticity. The primary design consideration for using FRP is to ensure that the material is used economically and in a manner that takes advantage of its structural enhancements specifically. Although, orientation of fibres also create a material weakness perpendicular to the fibres. Thus fibre reinforcement and orientation affects strength, elasticity, rigidity of a product and hence the operation of the final product itself. FRP products are a cost effective alternative to steel in many of the harshest industrial environments.
The advantages of FRP products over other materials include:
- Corrosion Resistance
- Operation in aggressive environments is possible.
- Little or no coating or treating required.
- Low maintenance requirements
- Designed and engineered to last, composite structural materials are virtually maintenance free.
- Impact resistance
- Inherent flexibility allowing products to resist impact and failure.
- Non-conductive and Non metallic
- FRP constructions provide additional safety by stopping sparks and potential electrical hazards.
- Fire Retardant
- FRP has a low flame spread index.
- High strength/weight ratio
- The strong, but light weight alternative where heavy lifting or access is an issue.
- Reduced installation time and cost
- FRP products are easier and lighter to install. Normal ‘hand tools’ are used to make adjustments.
We develop many electric vehicle parts and entire body of e rickshaws in fibreglass material, which provides more strength and being light in weight, is beneficial for battery mileage and longer life of electric and mechanical parts of these vehicles.
