Our 1/2" chopped carbon fiber is a long-strand, high-strength reinforcement filler designed to deliver maximum structural support in composite and marine applications. The extended fiber length improves bridging across gaps and enhances load distribution, making it ideal for critical repairs and fabrication work.

• Recommended Use: Structural reinforcement in laminating, filleting, gap-filling, and composite layups
• Fiber Length: 1/2 inch (12.7 mm)
• Resin Compatibility: Compatible with epoxy, polyester, and vinyl ester resins
• Note: Epoxy resin provides superior bond strength and performance
• Mix Ratio: Gradually add chopped fiber to mixed resin until the desired consistency is reached. For a thick, paste-like structural mix, use approximately 1 quart of resin with 1 to 1.5 quarts of chopped carbon fiber
• Appearance: Coarse black chopped strands
• Key Properties:
• Excellent tensile and flexural strength
• Improved gap-bridging due to longer fibers
• Electrically conductive
• Lightweight and corrosion-resistant
• Application Tips: Mix thoroughly into fully catalyzed resin to ensure even dispersion. Ideal for high-load repairs in transoms, bulkheads, stringers, and custom carbon laminates.

1/2" chopped carbon fiber is the go-to reinforcement for heavy-duty marine builds and repairs where long fiber length and structural integrity are paramount. For best results, use with epoxy resin to achieve optimal bonding and mechanical performance.
