ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ

How to cut carbon fiber sheets?

Cutting carbon fiber sheets requires specialized tools and techniques to ensure clean edges, prevent delamination, and minimize harmful dust. Here are the most effective methods:

1.Tools & Equipment

  • Diamond/Grit-Coated Blades:
  • Use carbide-tipped or diamond-coated blades (for saws) to reduce fraying.
  • Example: Diamond abrasive cutoff wheels (for angle grinders).
  • CNC Machines:
  • Ideal for precision cuts (laser/waterjet/CNC routers) with minimal material stress.
  • High-Speed Steel (HSS) Tools:
  • Suitable for thin sheets but wear out faster than carbide.

2.Step-by-Step Cutting Methods

  • Using a Circular Saw or Jigsaw
  • Secure the Sheet: Clamp firmly to prevent vibration.
  • Mark the Cut Line: Apply masking tape over the cut area to reduce splintering.
  • Cut Slowly: Use low-to-medium speed to avoid heat buildup.
  • Wear PPE: Respirator, goggles, and gloves (carbon dust is hazardous).
  • Waterjet Cutting
  • Best for complex shapes; no heat damage but requires specialized equipment.
  • CNC Laser Cutting
  • Limited use (may burn resin); CO₂ lasers work but generate toxic fumes.

3.Safety Precautions

  • Ventilation: Always work in a well-ventilated area or use dust extraction systems.
  • Dust Control: Wet cutting or vacuum attachments reduce airborne particles.
  • Protective Gear: N95 respirator, long sleeves, and eye protection.

4.Post-Cutting Finishing

  • Deburring: Sand edges with 120–400 grit sandpaper.
  • Sealing: Apply epoxy or sealant to exposed edges to prevent fraying.

5.Common Mistakes to Avoid

  • ✖ Using dull blades (causes rough edges).
  • ✖ High-speed cutting (melts resin or delaminates fibers).
  • ✖ Ignoring dust management (health risk).

Carbon fiber sheets can be shaped using various techniques depending on the desired geometry, production volume, and performance requirements. Here are the primary methods:
