TIPS FOR
CUTTING
CARBON
FIBRE
WITHOUT THE
COMPLICATIONS
Carbon fibre is a favourite material
in automotive, aerospace, and
high-performance industries thanks
to its strength-to-weight ratio and
rigidity. However, cutting it can be
tricky. Poor techniques can lead
to frayed edges, tool wear, and
even health hazards from airborne
dust. With the right approach,
these challenges can be managed
effectively, saving time, money, and
stress on the workshop floor.
1. Choose the Right Tools
Selecting the correct cutting tools
is the first step. High-speed steel
blades, diamond-coated tools, and
tungsten carbide tips can reduce
fraying and wear. For larger sheets
or high-volume cutting, consider
CNC machines or automated saws to
ensure precision and consistency.
2. Control the Feed Rate
Feed rate is critical. Too fast, and
fibres splinter; too slow, and
heat build-up can damage both
the material and the tool. Aim
for a steady, moderate pace,
and always follow manufacturer
recommendations for feed and
speed.
3. Use Proper Support and Clamping
Secure the material firmly to prevent
vibration, which causes uneven cuts
and delamination. Support on both
sides of the cut, especially for thin
sheets, can dramatically improve
finish quality.
4. Minimise Dust and Keep Safe
Carbon fibre dust is not just messy;
it can be harmful if inhaled. Use
dust extraction systems and wear
appropriate PPE, including respirators
and gloves. Wet cutting is also an
option for specific setups, keeping
fibres contained and tools cooler.

5. Plan Your Cuts
Planning the sequence of cuts
avoids unnecessary handling and
reduces errors. Start with smaller
sections or less critical pieces to test
settings, then move on to the full
components. This approach reduces
waste and ensures consistent quality.
6. Maintain Your Tools
Carbon fibre is abrasive, and blades
will wear faster than with traditional
materials. Regular inspection,
sharpening, and replacement extend
tool life and maintain cut quality.
7. Train Your Team
Even the best equipment cannot
compensate for lack of experience.
Training operators on correct
techniques, tool care, and safety
protocols is crucial for a productive,
safe workshop.
Why It Matters
Efficient and clean carbon fibre
cutting reduces rework, improves
product quality, and protects
workers. For high-volume workshops,
these tips save time, money, and
headaches while maintaining
the high standards required in
aerospace, automotive, and advanced
manufacturing.
