Carbon Fiber is a
polymer and is
sometimes known
as graphite fiber.
It is a very strong
material that is also
very lightweight.
Carbon fiber is five-
times stronger than
steel and twice as
stiff.

6. STRUCTURE
OF CARBON
FIBER
• Carbon atoms are bonded
together in crystals that are aligned
parallel to long axis of the fiber.
• Sheets of carbon atoms are
arranged in regular hexagonal
pattern.
• Cross-sectional view:
• Trilobal pattern of C-
atoms.
• Longitudinal view:
• Rod like with wrinkles.

PROCESS
21/12/2022
• Melt spinning is one of the most
popular methods for manufacturing
polymeric filaments. While there are
several methods available for filament
production, melt spinning is the most
economical approach due to the absence
of solvents and the simplicity of the
process

FILAMENT
YARN
• Tenax™ filament yarn is a high-tech
carbon fiber product, which
significantly enhances properties in
thermoset and thermoplastic
composites, including aerospace,
automotive and general industrial
applications.
