Aluminum alloy 6082 is a medium strength
alloy with excellent corrosion resistance. It has the highest strength of the
6000 series alloys. Alloy 6082 is known as a structural alloy. In plate
form, Aluminium alloy 6082 is the alloy most commonly used for
machining. As a relatively new alloy, the higher strength of Aluminum
alloy 6082 has seen it replace 6061 in many applications. The addition
of a large amount of manganese controls the grain structure which in turn
results in a stronger alloy.
In the T6 and T651 temper, Aluminum
alloy 6082 machines well and produces tight coils of swarf when chip
breakers are used.

How is Carbon Fiber Made?
http://www.zoltek.com/carbonfiber/how-is-it-made/
The raw material used to make carbon fiber is
called the precursor. About 90% of the carbon fibers produced are made from
polyacrylonitrile (PAN). The remaining 10% are made from rayon or petroleum
pitch. All of these materials are organic polymers, characterized by long
strings of molecules bound together by carbon atoms. The exact composition of
each precursor varies from one company to another and is generally considered a
trade secret.
During
the manufacturing process, a variety of gases and liquids are used. Some of
these materials are designed to react with the fiber to achieve a specific
effect. Other materials are designed not to react or to prevent certain
reactions with the fiber. As with the precursors, the exact compositions of
many of these process materials are considered trade secrets.
The
process for making carbon fibers is part chemical and part mechanical. The
precursor is drawn into long strands or fibers and then heated to a very high
temperature with-out allowing it to come in contact with oxygen. Without
oxygen, the fiber cannot burn. Instead, the high temperature causes the atoms
in the fiber to vibrate violently until most of the non-carbon atoms are
expelled. This process is called carbonization and leaves a fiber composed of
long, tightly inter-locked chains of carbon atoms with only a few non-carbon
atoms remaining.
Here
is a typical sequence of operations used to form carbon fibers from
polyacrylonitrile (PAN):
Spinning
·
Acrylonitrile plastic powder is mixed with
another plastic, like methyl acrylate or methyl methacrylate, and is reacted
with a catalyst in a conventional suspension or solution polymerization process
to form a polyacrylonitrile plastic.
·
The plastic is then spun into fibers using
one of several different methods. In some methods, the plastic is mixed with
certain chemicals and pumped through tiny jets into a chemical bath or quench
chamber where the plastic coagulates and solidifies into fibers. This is
similar to the process used to form polyacrylic textile fibers. In other
methods, the plastic mixture is heated and pumped through tiny jets into a
chamber where the solvents evaporate leaving a solid fiber. The spinning step
is important because the internal atomic structure of the fiber is formed
during this process.
·
The fibers are then washed and stretched to
the desired fiber diameter. The stretching helps align the molecules within the
fiber and provide the basis for the formation of the tightly bonded carbon
crystals after carbonization.
Stabilizing
·
Before the fibers are carbonized, they need
to be chemically altered to convert their linear atomic bonding to a more
thermally stable ladder bonding. This is accomplished by heating the fibers in
air to about 390-590° F (200-300° C) for 30-120 minutes. This causes the fibers
to pick up oxygen molecules from the air and rearrange their atomic bonding
pattern. The stabilizing chemical reactions are complex and involve several
steps, some of which occur simultaneously. They also generate their own heat,
which must be controlled to avoid overheating the fibers. Commercially, the
stabilization process uses a variety of equipment and techniques. In some
processes, the fibers are drawn through a series of heated chambers. In others,
the fibers pass over hot rollers and through beds of loose materials held in
suspension by a flow of hot air. Some processes use heated air mixed with
certain gases that chemically accelerate the stabilization.
Carbonizing
·
Once the fibers are stabilized, they are
heated to a temperature of about 1,830-5,500° F (1,000-3,000° C) for several
minutes in a furnace filled with a gas mixture that does not contain oxygen.
The lack of oxygen prevents the fibers from burning in the very high
temperatures. The gas pressure inside the furnace is kept higher than the
outside air pressure and the points where the fibers enter and exit the furnace
are sealed to keep oxygen from entering. As the fibers are heated, they begin
to lose their non-carbon atoms, plus a few carbon atoms, in the form of various
gases including water vapor, ammonia, carbon monoxide, carbon dioxide,
hydrogen, nitrogen, and others. As the non-carbon atoms are expelled, the
remaining carbon atoms form tightly bonded carbon crystals that are aligned
more or less parallel to the long axis of the fiber. In some processes, two
furnaces operating at two different temperatures are used to better control the
rate of heating during carbonization.
Treating
the surface
·
After carbonizing, the fibers have a surface
that does not bond well with the epoxies and other materials used in composite
materials. To give the fibers better bonding properties, their surface is
slightly oxidized. The addition of oxygen atoms to the surface provides better
chemical bonding properties and also etches and roughens the surface for better
mechanical bonding properties. Oxidation can be achieved by immersing the
fibers in various gases such as air, carbon dioxide, or ozone; or in various
liquids such as sodium hypochlorite or nitric acid. The fibers can also be
coated electrolytically by making the fibers the positive terminal in a bath
filled with various electrically conductive materials. The surface treatment
process must be carefully controlled to avoid forming tiny surface defects,
such as pits, which could cause fiber failure.
Sizing
·
After the surface treatment, the fibers are
coated to protect them from damage during winding or weaving. This process is
called sizing. Coating materials are chosen to be compatible with the adhesive
used to form composite materials. Typical coating materials include epoxy,
polyester, nylon, urethane, and others.
·
The coated fibers are wound onto cylinders
called bobbins. The bobbins are loaded into a spinning machine and the fibers
are twisted into yarns of various sizes.
Calfee's Carbon Frame Repair
Rumors of your bicycle's death may be greatly
exaggerated. Here, we clear up some of the confusion over when your carbon
frame is done for—and when it can be brought back to life.
By
Matt Phillips
What Is Repairable?
According to Heather Ross, the former frame-repair service manager at Calfee Bicycles, in La Selva Beach, California, most damage can be fixed. Calfee has mended more than 6,000 frames since 2003. Shawn Small, of Portland, Oregon-based Ruckus Components, who has fixed more than 200 bikes, agrees.
"Pretty much anything can be repaired," he says, noting that the process of layering carbon, compressing the frame, and curing the new material is similar to the way new carbon bikes are made.
This type of work is not limited to minor damage; the pros can fix tubes snapped through and frames snapped into multiple pieces. Bottom-bracket shells can be replaced; cable stops and front-derailleur braze-ons can be mended.
Repairs can be done on more than frames, too. Some companies will fix wheels as long as the brake track is not damaged. Liability concerns, however, seem to dissuade most companies from working on forks and handlebars.
Beyond repairing damage, the same techniques can be used to add carbon to a frame—for example, to lengthen an integrated seatmast, if you want to sell your frame to a taller friend.
There are some limits, though, especially when carbon dropouts are involved. Calfee doesn't touch carbon dropouts, but its crew can sometimes graft on new ones, along with stays from a compatible donor frame. (Perhaps USA Cycling should include a donor option line on racing licenses, in case of crash damage.)

How Is It Done?
"Technologically, there's nothing about carbon that takes special skill to repair," says Cervélo engineer Damon Rinard. The procedure starts with removal of the damaged carbon. Next, the area surrounding the damage is sanded, tapering toward the missing fibers. New layers of carbon fabric are used to rebuild the affected area, then cured. Finally, the repair is sanded to match the original frame shape.
The greater challenge is restoring the original finish, and quality work can set better jobs apart. Typically, painted frames can be made to look close to what they did when new, for a (sometimes high) price. In other cases the repair is left unpainted, for a battle-worn look.
