Carbon fiber raw materials;Carbon fibers (carbon fibre), as the name implies, it not only has natural intrinsic
characteristics of carbon materials, and both the soft and machinability of textile fiber, is a new generation
of reinforcing fiber.Compared with the traditional glass fiber (GF), young's modulus is its three times as
much;It with kay fulla fiber (KF - 49), compared to not only the young's modulus is its 2 times the left and
right sides, and insoluble in organic solvents, acid, alkali is not expanding, the corrosion resistance to
excel.Some scholars in 1981 will PAN CF immerse in strong alkali NaOH solution, time has past more than
20 years, it still keep fibrous form.Raw materials or materials, is used in the manufacture of goods, the
human device, component, machines or other products of the material.Material is the material, sometimes
people also known as raw materials, but not all substance can be referred to as the material.Such as fuel
and chemical raw materials, industrial chemicals, food and drugs, are generally not material.
Carbon fiber is the carbon content is higher than 90% of inorganic polymer fiber.Carbon content is higher
than 99% of graphite fiber.Carbon fiber axial strength and high modulus, creep, fatigue resistance, good
heat and electrical conductivity between non-metal and metal, small thermal expansion coefficient, good
corrosion resistance, low density of fiber, X-ray permeability is good.But its poor resistance to impact,
easy to damage, oxidation, under the action of a strong acid and metal composite metal carbide happens,
carburizing and electrochemical corrosion phenomena.Therefore, the carbon fiber surface treatment
before use must be.
Edit the period of preparation of carbon fiber can be respectively with polyacrylonitrile fiber, pitch fiber
and rayon silk or phenolic fiber made by carbide;According to the state is divided into filament, short-fiber
and chopped fiber;According to the mechanical properties can be divided into general and high
performance.Universal carbon fiber strength is 1 billion MPa (MPa), modulus of 100 gpa.High-performance carbon fiber is divided into high strength type (2000 mpa strength, modulus of 250 gpa)
and high model (modulus of 300 gpa above).Strength is greater than 4000 mpa is also known as ultra
high strength type;Modulus is larger than 450 gpa are called super model.With the development of
aerospace and aviation industry, but also the carbon fiber with high strength and high stretch type, its
elongation is more than 2%.Consumption is the largest polyacrylonitrile PAN based carbon fiber.
Commonly used carbon fiber is mainly polyacrylonitrile carbon fiber and carbon fiber with asphalt.The
manufacture of carbon fiber includes fiber spinning, thermal stabilization (oxidation), carbonization and
graphitization four process.With the chemical change include, such as dehydrogenation and cyclization,
oxidation and deoxidization.
