About FRP
• Fibre-reinforced plastic is a
composite material made of a
polymer matrix reinforced with
fibers.
• The fibers are usually glass, carbon,
aramid, or basalt.
• Rarely, other fibers such as paper,
wood, or asbestos have been used

PROCESS DESCRIPTION
• FRP involves two distinct processes, the first is the process whereby the
fibrous material is manufactured and formed, the second is the process
whereby fibrous materials are bonded with the matrix during moulding
• When combined with various agents to enhance or in any way alter the
material properties of polymers the result is referred to as plastic.
• Composite plastics refer to those types of plastics that result from bonding
two or more homogenous materials with different material properties to
derive a final product with certain desired material and mechanical
properties.
• Fibre reinforced plastics are a category of composite plastics
that specifically use fibre materials to mechanically enhance
the strength and elasticity of plastics.
• The original plastic material without fibre reinforcement is
known as the matrix. The matrix is a tough but relatively weak
plastic that is reinforced by stronger stiffer reinforcing
filaments or fibres.
COMMONLY USED FIBRES

GLASS
• Insulating material
• To form a very strong and light FRP
composite material called glass-
reinforced plastic(GRP),popularly
known as “fibre glass”
• Not as strong or as rigid as carbon
fibre, it is much cheaper and
significantly less brittle.
CARBON
• Fibres about 5-10 µm in diameter and
composed mostly of carbon atoms
• Carbon atoms are bonded together in
crystals that are more or less aligned
parallel to the long axis of the fibre.
• The crystal alignment gives the fiber
high-strength-to volume ratio (make
it strong for its size.)
• High stiffness, high tensile strength,
low weight, high chemical resistance,
high temperature tolerance and loew
thermal expansion.
ARAMID
• Class of heat-resistant and strong
synthetic fibres. They are used in
aerospace and military applications,
for ballistic rated body Armor fabric
and ballistic composites.
• eg: Kevlar,Nomex

Silicon, aluminium oxide and metal wires are also
used as reinforcing material
The polymer is usually
• Epoxy vinyl ester
• Polyester
• Thermosetting plastic
• Phenol formaldehyde resins
The reason the fiber was discussed in more detail is because they are what
actually differentiate the FRP from its parent polymer.

PARTICLE REINFORCED
• The most imporant feature is the equidistribution of particles in all direction.
• The strength of the bonding at matrix particle interface dictates the
mechanical properties of composite.
