T700 Unidirectional Carbon Fiber Prepreg is a composite material made of carbon fibers that are pre-impregnated with a resin system. It is specifically designed to enhance the performance and durability of products while offering ease of use in manufacturing. The unidirectional arrangement of the carbon fibers ensures maximum strength in a single direction, making it ideal for structural applications that require stiffness, high tensile strength, and low weight.
T700 is a higher-performance carbon fiber from Toray.
It’s stronger and slightly stiffer than T300, commonly used in aerospace, high-end automotive, and advanced sporting equipment.
Typical properties of T700 fibers:
Tensile Strength: ~4.9 GPa
Tensile Modulus: ~230–240 GPa
Elongation at Break: ~2%
Density: ~1.78 g/cm³
Notice that the modulus is similar to T300, but the strength is significantly higher, meaning it can take more load before breaking.
Same as T300 UD: fibers are aligned in one direction only.
Provides maximum strength and stiffness along the fiber direction.
Often combined in multi-directional laminates to achieve specific mechanical properties.
Pre-impregnated with resin (usually epoxy).
Advantages:
Accurate fiber-to-resin ratio.
Cleaner and easier than manual wet-layup.
Controlled curing process: typically heat and pressure (oven or autoclave).
Handling:
Stored in a freezer before use to prevent premature curing.
Requires specific curing cycles depending on the resin system.
Layup: Begin by laying out the prepreg sheets in a mold or onto a tool. The unidirectional fibers should be oriented in the direction of the primary load.
Curing: The prepreg material needs to be cured in an autoclave or oven at the specified temperature and pressure to achieve optimal bonding and performance.
Finishing: After curing, trim, sand, or finish the composite part to meet the required specifications for your application.
Unmatched Strength-to-Weight Ratio: The T700 prepreg provides an exceptional balance of strength and low weight, making it perfect for industries where reducing weight without compromising performance is critical.
Superior Fatigue Resistance: Thanks to the advanced resin system, T700 carbon fiber exhibits excellent fatigue resistance, making it an ideal choice for long-lasting, high-performance applications.
High Stiffness: The unidirectional fiber alignment increases stiffness in the primary loading direction, resulting in superior load-bearing capabilities.
Customization: Available in various thicknesses and widths, T700 Unidirectional Prepreg can be tailored to meet specific requirements for different projects and industries.
Thermal Stability: T700 prepreg maintains its strength and stability under a wide range of temperatures, making it suitable for both extreme heat and cold environments.
Consistent Quality: Each batch of T700 prepreg is rigorously tested for quality, ensuring reliable and uniform performance for every use.
