CONCLUSION.
INTRODUCTIONA carbon fiber is a long, thin strand material
about 0.0002-0.0004 in (0.005-0.010 mm) in
diameter and composed mostly of carbon atoms.
Carbon fibers have revolutionized the technology
of materials.
A super strong material that's also extremely
lightweight.
Thin strands of carbon- even thinner than human
hair.
HOW IS CARBON FIBER MADE?
Production from two sources -:
Polyacrylonitrile (PAN)
Pitch
The raw material used to make carbon fiber is
called the precursor.
Currently, the former PAN-based carbon fiber is
said to be the mainstream
CARBON FIBER VS
METAL Carbon fibers are twice as stiff as
steel and five times as strong as
steel, (per unit of weight).
It is lighter than aluminum and
stiffer than titanium.
which makes it great for almost anything that requires high strength and low weight.
PROPERTIES
Carbon fiber has very high tensile
strength.
It has low thermal expansion.
It is a light weight material having
low density.
It is a good conductor of electricity.
It can wear a high resistance.
ADVANTAGES It has long working life.
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.
High tensile strength.
Electrically and thermally conductive.
Light weight and low density.
High abrasion and wear resistance.
DISADVANTAGE
It is very costly.
It is little bit harmful for the human
body as it cause some form of
cancer of the lungs.
APPLICATION
Aerospace and Aircraft Industry.
Sports equipments.
Automobile parts.
Civil Engineering.
Energy production; windmill blades.
Medical applications.

AEROSPACE AND
AIRCRAFT INDUSTRY In December 2009
Boeing flew the 787 Dreamliner for the first time. One of the major design features of the Dreamliner was its lightweight, a result of the use of composite materials. 50% of the Dreamliner’s structure is made up of composite
AEROSPACE AND AIRCRAFT
INDUSTRY When it comes to airliners, weight
is money. The heavier a plane is,
the more fuel it takes to drive it
through the air. The more fuel it
takes, the more it costs.
in June 2013 Airbus is flight testing
the A350XWB. The latest Airbus
now boast a 53% usage of
composite material among its long
lists of new features
Most of the A350 XWB's wing is
made of the lightweight carbon fiber
reinforced plastic (CFRP)
composites
SPORTS EQUIPMENTS Tennis rackets, golf clubs,
softball bats, hockey sticks, and products commonly manufactured with carbon fiber reinforced composites
Anywhere where high performance is required carbon fiber's superior strength to weight ratio offers significant advantages, and sporting goods are no exception. It is used to replace or reduce metal, wood and steel content in a wide variety of sports applications.
SPORTS EQUIPMENTS
An obvious requirement of any high performance racing car, motorbike or powerboat construction is that it should be strong and lightweight.
Formula One cars are some of the most expensive pieces of sporting equipment and as a result, a huge amount of money and research has been put into the development of safety and performance of various materials and composites over the years
SOME OF THE SPORTS
APPLICATIONS IN WHICH CARBON
FIBER IS USED
Sailboats
Gliders
Fishing rods
Running shoes
Bicycles
Rowing shells
archery arrows
CONSTRUCTING UP OF WIND MILL
BLADES
Carbon fiber is used to
provide
the necessary stiffness,
without adding a
tremendous amount of
weight. This is
important, because the
lighter a wind turbine
blade is, the more
efficient it is at
creating electricity
CIVIL ENGINEERING
Due to the characteristics of the lightweight and high stiffness of carbon fiber composite materials, they are widely used as reinforcing materials in building structures, pier of expressways and Shinkansen bullet trains. Recently, they began to be used as earthquake-proof or its supportive materials for buildings.
MEDICAL
APPLICATIONS The use of carbon fiber to
strengthen of damaged
cruciate ligaments in the
knee is being researched,
but probably the most well
known medical use is that of
prosthetics – artificial limbs.
South African athlete Oscar
Histories brought carbon
fiber limbs to prominence
when the International
Association of Athletics
Federations failed to ban
him from competing in the
Beijing Olympics.
His controversial carbon
fiber right leg was said to
give him an unfair
advantage, and there is still
considerable debate about
this
ELECTRONICS FIELD
Apple
macbook,lenovo
think pad,SONY VAIO
SZ etc.
Due to the
characteristics of the
high strength, high
stiffness and low
specific gravity of
carbon fiber
composite materials,
they are widely used
in slim-type or
weight- saving
notebook and tablet
PCs.
May 9th 2010, Former President Dr A P J Abdul Kalam
on Sunday inaugurated the country's first carbon fiber
manufacturing facility. The Rs 250-crore set up will
produce lightweight material for use in defence,
aerospace and infrastructure — under technology
transfer from the Council of Scientific and Industrial
Research's (CSIR) National Aerospace Laboratory
(NAL), which had developed the ultra-light material for
the Light Combat Aircraft.

fiber plant
FUTURE OF CARBON
FIBERBecause of its high tensile strength and
light weight, many consider carbon fiber
to be the most significant manufacturing
material of our generation. Carbon fiber
may play an increasingly important role
in areas such as-
Energy. Windmill blades, natural gas storage
and transportation, fuel cells.
FUTURE OF CARBON
FIBER
Carbon nanotubes. Semiconductor materials, spacecraft, chemical sensors, and other uses
Aircraft: Defense and commercial Oil exploration.
Deep water drilling platforms, drill pipes.
ircraft. Unmanned aerial vehicles.
Construction. Lightweight pre-cast concrete, earthquake protection.
The growth of carbon fiber is fast, and in just 5 years, I imagine this list will be much longer
FUTURE OF CARBON
FIBER IN AUTOMOBILE
A BMW Press Release (2009) details... ‘The
BMW Group and the SGL Group have agreed on
the establishment of a joint venture for the
production of carbon fibers and textile semi-
finished products (CFRP) for use in vehicle
construction. The total investment volume is $
90 million in the first development phase’.
In December 2011 General Motors announced
that it is working on carbon fiber composites for
mass production of automobiles.
FUTURE OF CARBON FIBER IN
AUTOMOBILE INDUSTRY
As costs come down,
carbon fiber is being more
widely adopted in
automobiles Currently
used just for high
performance vehicles,
carbon fiber technology is
moving into wider use.
Supercar bodies are built
now, but its wider use is
likely to be in internal
components such as
instrument housings and
seat frames.
CONCLUSION
In 2005, carbon fiber had a $90
million market size. Projections
have the market expanding to $2
billion by 2015. To accomplish this,
costs must be reduced and new
applications targeted.
