Our 1/4" chopped carbon fiber is a premium structural filler designed to enhance the mechanical properties of resin systems. With its high strength-to-weight ratio and stiffness, it's ideal for reinforcing structural bonds, laminates, and high-stress areas in boatbuilding and composite fabrication.

• Recommended Use: Structural reinforcement in bonding, filleting, and laminating
• Fiber Length: 1/4 inch (6.35 mm)
• Resin Compatibility: Compatible with epoxy, polyester, and vinyl ester resins
• Note: Best bonding performance is achieved with epoxy resin
• Mix Ratio: Add gradually to resin until desired consistency is reached. For a paste-like structural mix, use approximately 1 quart of resin with 1 to 1.5 quarts of chopped carbon fiber
• Appearance: Short black carbon fiber strands
• Key Properties:
• Extremely high tensile strength
• Lightweight and stiff
• Electrically conductive
• Application Tips: Blend into fully mixed resin using slow, thorough stirring to ensure uniform distribution. Suitable for reinforcing fillets, transoms, stringers, and custom carbon fiber layups.

This filler is trusted by professionals for demanding applications where strength, weight savings, and durability are non-negotiable. Use with epoxy for maximum bond strength, or with polyester/vinyl ester where compatibility is sufficient for the task.
