FIBERS :



A fiber is a composite material that has been drawn into a long and thin filament.

Classifications:
  •     Glass fibers.
  •     Armid fibers.
  •     Carbon fibers.

Glass fibers:
  •     E- glass fiber (Electrical)
  •     S-glass fiber (High strength)

E-glass fiber:

The composition of E-glass ranges from 8-13%  , 12-16%  , 16-25% CaO,  .

1.    Its tensile strength is about 3.44GPa.

2.    It is used for continuous fibers.

S-glass fiber:

        Composition are 10% Mgo, 25%   , 65% .

1.    Its tensile strength is over 650 Ksi.
2.    Used in military applications.



Armid fibers:

1.    It is characterized by low density and high strength.
2.    It is used as ballistic protection, ropes and cables.

Carbon fibers:


    Composite materials made by during carbon fibers for reinforcing plastic resin matrices such as epoxy are characterized by having a combination of light weight, high stiffness and high strength.
