What is fibre reinforced plastic?
- Fiber reinforced plastic (FRP) is a type of plastic in which the strength of low strength plastic material is increased by means of high strength of fibers.
- Fiber reinforced plastics contain two main things
- The function of the matrix is to support and hold the fibers in the correct position.Matrix also prevents fibers from surface damage and environmental conditions.
- The matrix material should show stability with moisture and temperature. The FRP fibres are the main component which bears the actual load.
- The bond between the fibres and the matrix is generally made with the help of a chemical adhesive.
- The length of fibers should be more so that the strength of bond between matrix and fibers is more than the tensile strength of fibers.
Advantages of fibre reinforced plastic:
- It is lightweight
- It has high strength
- It has high modulus of elasticity
- It has high resistance to fatigue failure
- It has good resistance to corrosion
Disadvantages of fiber reinforced plastic:
- The design of components made from FRP is complex
- The manufacturing and testing of FRP components is highly specialized
Types of fiber reinforced plastics
- Glass reinforced plastic (GRP)
- Carbon reinforced plastics (CRP)
1. Glass reinforced plastic:
Advantages of glass reinforced plastic
- They can be easily drawn into fibers from molten state
- Glass is cheaper and readily available
- Glass fiber is relatively strong
- Glass is chemically inert with respect to plastic matrix materials
Disadvantages of glass reinforced plastic
- It has poor rigidity and stiffness
- Its application is limited to a temperature below 300-degree Celsius
It is used as a manufacturing material in the following things.
- In the manufacturing of Automotive bodies due to its low weight
- Valve bodies
- Pump castings
- Storage containers
2. Carbon reinforced plastics:
Advantages of carbon reinforced plastics
- It has maximum strength compared to other reinforcing fibers
- It retains its strength at elevated temperatures
- At normal temperature moisture, acids and solvents do not affect carbon fibers
- They are relatively cheap
Disadvantages of carbon reinforced plastics
- There is only one limitation of carbon reinforced plastic. The manufacturing techniques associated with CRP are relatively complicated.
Carbon reinforced plastics are used for the manufacturing of
- Pressure vessels
- Aircraft components
- Casting of rocket motors
