This document provides an overview of carbon fiber, including its history, structure, types, manufacturing process, properties, and applications. Carbon fiber was first created in 1860 but has primarily been developed since the 1950s through improvements in manufacturing. It is produced from polymer precursors like polyacrylonitrile and petroleum pitch. The manufacturing process involves spinning the precursor into filaments, then oxidizing, carbonizing, and applying surface treatments to produce the final carbon fiber. Carbon fiber has very high strength and stiffness to weight ratios, making it useful for applications in aerospace, automotive, civil engineering and sports equipment.

Cite the distinction between graphite and carbon. Carbon and graphit.pdfalokkesh
Cite the distinction between graphite and carbon. Carbon and graphite fibers are manufactured
by pyrolysis. Describe the process to produce fibers.
Solution
Carbon:
1)“Carbon” comes from the Latin word “carbo,” which in English means “charcoal.” It is an
element represented as the letter “C” and bearing the atomic number 6. Carbon is the fourth most
abundant element in the world and is essential to all living things and their respective processes.
All living things contain carbon.
2)Carbon produces the softest material (graphite) and the hardest substance (diamond). The main
difference among carbon substances is how the carbon forms in each matter. Carbon atoms bond
in chains and rings. In every carbon substance, a unique formation of carbon can be produced.
3)Carbon has a wide variety of uses both as pure carbon and carbon compounds. Primarily, it
acts as hydrocarbons in the form of methane gas and crude oil. Crude oil can be distilled into
gasoline and kerosene. Both substances serve as fuel for warmth, machines, and many others.
4)Carbon is also responsible for forming water, a necessary compound for life. It also exists as
polymers such as cellulose (in plants) and plastics.

6)Carbon is also responsible for forming water, a necessary compound for life. It also exists as
polymers such as cellulose (in plants) and plastics.
Graphite :
1)Graphite is an allotrope of carbon. It means that it is a substance made of pure carbon and is
made of only carbon. Other allotropes include diamonds, amorphous carbon, and charcoal.
2)Graphite comes from the Greek word “graphein,” which in English means “to write.” Formed
when carbon atoms link with each other into sheets, graphite is the most stable form of carbon.
3)Graphite is soft but very strong. It is resistant to heat and, at the same, a good conductor of
heat. Found in metamorphic rocks, it appears as a metallic but opaque substance in a color that
varies from dark grey to black. Graphite is greasy, a characteristic that makes it a good lubricant.
4)Graphite is also used as a pigment and a molding agent in glass manufacturing. Nuclear
reactors also use graphite as an electron moderator
b) process of manufacturing of Carbon and graphite fibers:
A precursor material, which is rich in carbon, is subjected to pyrolysis to extract its carbon
content.
Pyrolysis Pyrolysis: Thermochemical chemical decomposition decomposition of organic organic
material material when it is subjected subjected to elevated temperatures, but no oxygen.
Through such a process, the precursor organic material breaks down into gases, liquids, and a
solid residue which is rich in carbon.
Precursor: Precursor: It is a carbonrich chemical chemical compound, com.
Carbon Fibre is one of the most recent developments in the field of composite materials and is one of the strongest fibers known to man. It is usually the first choice of fibre if something very strong and very light is required.
Carbon fibre was originally developed in space technology, but has now been adopted in many other areas of manufacture. Racing car monocoques and aeroplane wings are usually constructed of carbon fibre.
With the decrease in its cost over recent years, it is fast becoming one of the leading materials in many areas, including performance sport equipment, transport, scientific experiments and even wallets and watches.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

HISTORY
When was carbon

Although carbon fiber has been
around for more than 150 years, it
has only been through
manufacturing process
improvements in the last half century
or so that its excellent strength-to-
weight and stiffness-to-weight ratios
have been achieved. These modern
advances, coupled with decreases in
manufacturing costs over the last
couple of decades, are what have
made carbon fiber become such a
popular material for design
engineers to use in some of today's
greatest technological advances.
Union Carbide Parma Technical

petroleum-based carbon fibers
6. Carbon Fibers Were Developed In The 1950s By Heating Strands
of Rayon Until They Carbonized.
In The Early 1960s, A Process was Developed using Polyacrylonitrile As
a raw material.
During The 1970s, Experimental Work To Find alternative raw materials
led to the introduction of carbon fibers made from a petroleum pitch
derived from oil processing.

The atomic structure of carbon fiber is
similar to that of graphite, consisting
of sheets of carbon atoms arranged
in a regular hexagonal patter
(graphene sheets), the difference
being in the way these sheets interlock.

carbonization of oil/coal pitch precursor.
Pan type carbon fiber
A type of the fiber produced by carbonization of PAN
precursor (PAN:Polyacrylonitrile)
14. HOW IS CARBON FIBER MADE?
Production from two sources:-
•Polyacrylonitrile(PAN)
•Pitch
The raw material used to make carbon fiber is called the precursor.
15. MANUFACTURING
Each carbon filament is produced from a polymer such as
polyacrylonitrile (PAN), rayon, or petroleum pitch, known as a
precursor.
The precursor is first spun into filament yarns, using chemical
and mechanical processes to initially align the polymer atoms
in a way to enhance the final physical properties of the
completed carbon fiber.
