Vacuum Infusion Carbon Fiber Cloth

Optimized weave architecture for uniform resin distribution in closed-mold processes

Vacuum Infusion Carbon Fiber Cloth is specifically engineered to facilitate rapid, uniform resin flow during vacuum-assisted resin transfer molding (VARTM) and infusion processes. The fabric incorporates a balanced weave with controlled permeability, allowing resin to wet-out the reinforcement completely while maintaining a fiber volume fraction of 55%–60% in the final laminate. Surface treatments are tailored to minimize flow-front disturbances and reduce micro-void formation. The cloth is compatible with low-viscosity epoxy, vinyl ester, and polyester resin systems, and is available in areal weights ranging from 200 to 800 g/m². This product is designed for large-scale structural components where process reliability and laminate quality are critical.

Common Process Questions

How to avoid race-tracking along edges? Apply tacky tape or edge sealant; place flow media at least 20 mm from edges.
What is the optimal fiber volume fraction? Target 55% – 60% for balanced mechanical properties; adjust via compaction pressure.
Can this cloth be used with epoxy tooling resins? Yes. High-temperature epoxy systems (150 °C Tg) are compatible; verify sizing cure schedule.
How to store infused cloth after opening? Re-seal in moisture-barrier bag with desiccant; use within 7 days of opening.
Permeability-tested Void content < 1.5% Large part capable ASTM D4496 compliant

All specifications are validated using standardized infusion test panels per ASTM D6856 and CRAG test methods. Custom permeability grades available upon request for specific resin systems and processing conditions.
