FIBERS

3. Glass fiber is a material
consisting of numerous extremely
fine fibers of glass. Glass wool,
which is called "fiberglass"
today, was invented in 1932–
1933 by Russell Games .

Types of glass fiber
The major types of glass
fiber have been listed
below
•C-Glass Fiber
•AE-Glass Fiber
•A-Glass Fiber
•E-Glass Fiber

1. A-glass: With regard to its composition, it is close to window glass.
In the Federal Republic of Germany it is mainly used in the
manufacture of processed equipment. Alkali glass made with soda
lime silicate. Used where electrical resistivity of E-glass is not
needed. A-glass or soda-lime glass is the predominant glass used for
containers and windowpanes.
2. C-glass: This kind of glass shows better resistance to chemical
impact. Corrosive resistant glass made with calcium borosilicate.
Used in acid corrosive environments.

3. E-glass: This kind of glass combines the characteristics of
C-glass with very good insulation to electricity. Alkali free,
highly electrically resistive glass made with alumina-calcium
borosilicate. E-glass is known in the industry as a general-
purpose fiber for its strength and electrical resistance. It is the
most commonly used fiber in the fiber-reinforced polymer
composite industry

Properties of Glass Fibres
1.It has more Incombustibility.
2.It has Corrosion resistance.
3.It has High strength at low densities.
4.It has Good thermal.
5.It has Sound insulation properties.
6.It has Some Special electrical properties.

Use of Glass fiber in civil
engineering
Glass fibers were first used to reinforce cement and
concrete in Russia.
However they were corroded by the highly alkaline
Portland cement matrix.
Therefore, alkali resistant glass fibers have been
subsequently developed in UK and other countries.

Glass fibers are available in the form of
continuous rovings, chopped strand mats, cranette,
wool, ropes and woven fabric.
Glass fibers coated with epoxy resin compounds
have also been tried out to protect them from alkali
attack by Portland cement.

COMPOSITE MATERIALS
Composite means Something made up of
distinct parts (or constituents).
A materials system composed of suitably
arranged mixture or combination of two or more
micro and macro constituents with an interface
separating them that differ in form and chemical
composition and are essentially insoluble in each
other.

13. Carbon Fiber
 Composed of carbon atoms bonded
together to form a long chain.
 A super strong material that’s also
extremely lightweight.
 Five times stronger than steel, two
times stiffer and about two-third
times less in weight.

Carbon Fiber
Carbon even thinner
than human hair.
 Strands can be
twisted together, like
yarn- can be woven
together, like cloth
extremely lightweight.

15. 15
Properties
Carbon fiber had very high tensile
strength.
It is a light weight material having low
density.
It has low thermal expansion.
It is a good conductor of electricity.
It can wear a high resistance.

16. 16
It has long working life.
It’s density is less than density of steel.
It is insensitive to change in temperature.
It’s properties is much better than any of the other metals.
It’s compressive strength is greater than all the reinforcing
material.
ADVANTAGES

17. DISADVANTAGE
It is very costly.
It is little bit harmful for the
human body as it cause some
form of cancer of the lungs. 17

18. 18
Automotive body is
also made up of the
carbon fiber.
It is used in making
sports equipment such as
light weight badminton
rackets, golf stick etc.
