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

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.

OTHER APPLICATION

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.

India gets first carbon

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.

CARBON FIBER MARKET

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.
