Correct Answer - Option 1 : Only II
Explanation:
Fibre reinforced composite(FRP):
- These materials consist of fibres of significant strength and stiffness embedded in a matrix with distinct boundaries between them.
- Both fibres and matrix maintain their physical and chemical identities, yet their combination performs a function which cannot be done by each constituent acting singly. It appears obvious that FRP having continuous fibres is indeed more efficient.
According to the matrix used these are
-
Polymer matrix composites: these are made of thermoplastic or thermoset resins reinforced with fibres such as glass, carbon or boron and matrix as Epoxy Polyimide, Polyester Thermoplastics & Polysulfone.
-
Metal matrix composites: consist of a matrix of metals or alloys reinforced with metal fibres such as boron or carbon and matrix as Aluminium, Magnesium, Titanium & Copper
-
Ceramic matrix composites: consist of ceramic matrices reinforced with ceramic fibres such as silicon carbide, alumina or silicon nitride. They are mainly effective for high-temperature applications. Matrix used are Silicon carbide, Alumina, Glass-ceramic & Silicon nitride
-
Carbon/carbon composites: consist of graphite carbon matrix reinforced with graphite fibres and matrix used is Carbon. In addition to the above, there are other types of composites as well. The flake composites consist of a matrix reinforced with flakes which may be of different types such as glass flakes, mica flakes and metal flakes. The distribution of the flakes throughout the matrix provides a considerable barrier to moisture, gas and chemical transport. It can suitably be used for obtaining high thermal and electrical resistance or conductivity.
