High modulus carbon fiber Plate 300mm*500mm*2.0mm laminate veneer
sheets, carbon fiber .
This carbon fiber plate unidirectional plate is layered up so that
all carbon fibers run in 0° direction
(parallel to the long direction) of the part. It is used to add
stiffness to almost any material: fiberglass,
foam, balsa wood, etc. The plate can be used for a variety of
applications such as aircraft and rocket
fuselages, surfboards, boat centerboards, guitar necks, etc.
One side of the laminate has been purposely roughened to facilitate
bonding to the surface. If bonding
on both sides is required, the smooth side should be roughened up
Carbon filaments are often made from the oxidation and thermal
pyrolysis of polyacrylonitrile material.
Polyacrylonitrile is a acrylonitrile-based polymer used in the
creation of some synthetic materials.
Polyacrylonitrile molecules are made of long chains which are
aligned by drawing continuous filaments.
When these chains are heated under the correct conditions they bond
side to side forming ladder
polymers. Narrow graphene sheets are formed which merge together to
make a single round filament.
This product is approximately 94-95% carbon. Instead of
polyacrylonitrile, pitch or rayon can also be
used although this produces a lower-quality fiber. If the carbon is
heat treated in the range of 1500-3000 degrees celcius, the fiber
a higher strength, higher molulus product.
The highest tensile strength (>800,000 psi) can be created by
heating the fiber between 1500 and 2000
degrees. The highest modulus of elasticity (77,000,000 psi) can be
obtained by heating the fiber material
from 2500 degrees to 3000 degrees. This balance between strength
and elasticity is what allows a carbon
fiber hood to be so strong but also so durable. Carbon fiber
density is about 1740 kg/m3. The three kinds
of carbon fiber are standard modulus, intermediate modulus and high
modulus. Tensile strength tends to
vary between 2000 MPa and 7000 MPa. Rayon used to be a more popular
precursor for carbon fibers
and is still used on some applications like rockets. However, it is
not much more common for PAN or even
pitch to be used. The fiber yarns can be processed in many ways.
