HexTow® Carbon Fiber HexTow® carbon fiber is the preferred carbon fiber for the world’s most advanced aerospace and industrial composite application

• Stronger than steel, lighter than aluminum & as stiff as titanium ¥¥High strength ¥¥High strain • PAN based fiber • Successive surface treatment to improve bonding • Sizing to improve handleability embrace the exploration of new ideas, to challenge the impossible and succeed beyond expectations. We have been pioneers at the forefront of the composites industry for over 50 years and will continue to pave the way for the future. HexTow® carbon fiber The primary building blocks for carbon fiber composite materials begin with Hexcel’s HexTow® carbon fiber which is the preferred carbon fiber...

Continuous fiber can be combined with all thermoset and thermoplastic resin systems. They are used for weaving, braiding, filament winding applications, unidirectional tapes for ATL and AFP processes and prepreg tow for fiber placement. Hexcel offers standard, intermediate and high modulus carbon fibers. While our IM fibers have become an industry standard, particularly the HexTow® IM7 carbon fiber, we continue to innovate and look for better ways to meet customers’ growing needs. Fiber Type Refer to specific product data sheets for more details on each product. * Tensile Modulus Calculated...

* Compatibility with these Matrices is considered theoretically compatible. Hexcel cannot guarantee their results.

Recommended Storage and Shelf Life The inherent properties of Hexcel’s unsized carbon fiber include: • Tow Tensile Strength • Tow Tensile Modulus • Tow Tensile Elongation • Fiber Density • Mass per Unit Length (yield) To enable consumer processing of carbon fiber, proprietary sizing agents are typically applied by Hexcel, such as G, GP, and GS Sizes. It has been found that the original processing characteristics of G Sized carbon fiber will essentially remain constant for at least one year from the date of manufacture while GP and GS Sized carbon fibers will essentially remain constant for...

Chopped fiber is used in compression and injection molding compounds to produce parts as varied as machine parts, gears and chemical valves. The finished products exhibit high strength and modulus, excellent fatigue and creep resistance, low thermal expansion, electrical and thermal conductivity, excellent friction and wear resistance, and low shrinkage. HexTow®, PAN based carbon fiber is available in 1/4 inch chopped fiber lengths, sized for compatibility with various resin matrix systems and processes. The chopped product is small, thin, rectangular flake, 1/4 inch long by 1/8 to 1/4 inch...

AFL Automated fiber layup ATL Automated tape layup AS Standard modulus fiber in the 33 Msi to 38 Msi range Filament The individual threads in a tow. Filaments can vary in diameter. Flexural Modulus: A number referring to a material’s stiffness. It is used to calculate how far a bar will bend when a bending load is applied. Units are normally millions of pounds per square inch. (106 psi) - Giga Pascals (gPa). In two materials of equal thickness, the one with a higher number is more resistant to deflection. Flexural Strength: Also known as bending strength. Describes how much non-moving load...
