Epoxy compatible Optimized sizing Superior adhesion

Carbon Fiber Woven Fabric For Epoxy Resin

Specially formulated woven reinforcement with optimized sizing chemistry for maximum interfacial bond strength with epoxy resin systems — ensuring superior wet-out, adhesion, and mechanical performance.

Sizing: Epoxy-optimized Weight: 60-1200 g/m² Tow: 1k-24k Weave: All patterns

Epoxy bond optimized

Carbon Fiber Woven Fabric For Epoxy Resin features a proprietary sizing formulation that is chemically matched to epoxy resin systems, ensuring optimal wet-out, adhesion, and stress transfer at the fiber-matrix interface. The sizing agent is applied during the final manufacturing stage and is characterized by a uniform distribution of polar functional groups that react with epoxy hardeners during cure. Available in a comprehensive range of tow sizes (1k to 24k), weave patterns (plain, twill, satin, unidirectional), and areal weights (60 to 1200 g/m²). The sizing is designed to maintain stability during storage while promoting rapid dissolution into the epoxy matrix during infusion, prepreg consolidation, or hand layup processes. This fabric is the preferred choice for high-performance applications where maximum structural integrity and durability are required.

≥65 MPa Interfacial shear strength
98% IFSS retention after 1000h at 80°C

Frequently Asked Questions

The fabric features a proprietary sizing chemistry that is formulated to be chemically compatible with epoxy resin systems. The sizing contains polar functional groups that react with epoxy hardeners during cure, creating a strong covalent bond at the fiber-matrix interface.

Perform a simple wet-out test by placing a drop of your epoxy resin on the fabric surface. Complete wet-out and resin penetration within 60 seconds at 25°C indicates proper compatibility. Contact our technical team for detailed compatibility testing protocols.

For moisture-sensitive epoxy systems, drying the fabric at 60°C for 2 hours prior to layup is recommended to remove adsorbed moisture. The sizing is designed to maintain its compatibility even after proper drying procedures.

The recommended cure schedule depends on your specific epoxy system. A typical post-cure cycle of 4 hours at 150°C is recommended for maximum glass transition temperature and interlaminar fracture toughness. Consult your resin supplier for specific cure parameters.
