Spread Tow Carbon Fiber Fabric: Advanced Lightweight Composite Materials
Spread tow carbon fiber fabric represents the cutting edge of composite reinforcement technology. This innovative material offers exceptional mechanical properties with significantly reduced weight compared to traditional carbon fiber fabrics. At Bulk Composites, we provide premium-quality spread tow fabrics engineered for applications where every gram matters and performance cannot be compromised.
What Is Spread Tow Carbon Fiber Fabric?
Spread tow fabric (STF) is a specialized carbon fiber reinforcement manufactured using an innovative spreading technology. Unlike conventional carbon fabrics where fiber tows are bundled in round or oval shapes, spread tow technology flattens these tows into ultra-thin, wide tapes before weaving. This process creates an exceptionally thin fabric with dramatically reduced crimp (fiber undulation).
The spreading process transforms standard carbon tows into flat, thin tapes that are then precisely woven into lightweight composite fabrics. This unique structure delivers several key advantages:
- Reduced fabric thickness (as thin as 0.02mm)
- Lower weight (starting from just 40 g/m²)
- Significantly straighter fibers
- Reduced crimp at weave intersections
- Superior mechanical properties

Significant Weight Reduction
Spread tow fabrics can reduce composite weight by up to 20% compared to traditional carbon fiber fabrics. This weight saving comes from both the thinner fabric structure and the reduced resin uptake during lamination.
Superior Mechanical Properties
The flatter, straighter fibers in spread tow fabrics provide enhanced stiffness and strength. With minimal crimp, fibers can carry loads more efficiently, resulting in improved tensile, compressive, and flexural properties.
Exceptional Surface Finish
The ultra-flat nature of spread tow fabrics creates composites with superior surface finish. The distinctive checkerboard pattern is not only functional but also aesthetically appealing for visible carbon applications.
Reduced Resin Consumption
The flat structure of spread tow fabric requires less resin to fully impregnate. This leads to higher fiber-to-resin ratios in the finished composite, enhancing mechanical properties while reducing weight and cost.
Enhanced Damage Tolerance
Spread tow fabrics demonstrate improved resistance to crack propagation and impact damage. The woven structure distributes impact forces more effectively than unidirectional materials, increasing overall durability.
Versatile Processing
Our spread tow fabrics are compatible with all standard composite manufacturing processes including hand lay-up, vacuum bagging, resin infusion, and prepreg molding techniques.
