A-6 UHN-40T UD carbon fiber prepreg

UHN-40T Unidirectional Carbon Fiber Prepreg Product Description

The UHN-40T unidirectional carbon fiber prepreg is a high-performance composite material that stands out as a cornerstone in advanced manufacturing, catering to industries where exceptional strength, lightweight properties, and customization are non-negotiable. As a specialized unidirectional prepreg, its defining feature is a fiber modulus of 40TON—an impressive metric that enables it to deliver robust structural support while remaining significantly lighter than traditional materials like steel or aluminum. What truly enhances its versatility is its adaptability in key manufacturing parameters: the carbon fiber surface density can be precisely calibrated to range from an ultra-light 10g/m², ideal for precision components requiring minimal weight, to a heavy-duty 1000g/m², designed for load-bearing structures that demand maximum strength. The prepreg’s width also offers flexible adjustment between 1 meter and 1.5 meters, seamlessly accommodating both small-batch, intricate projects and large-scale production runs such as wind turbine blades or aircraft panels. Adding to its customization potential, the resin system integrated into the UHN-40T can be tailored to meet specific customer needs, with options including high-temperature epoxy for aerospace applications, flame-retardant phenolic for industrial safety requirements, and flexible resins for sports equipment—each formulated to align with unique thermal, chemical, or mechanical performance demands.

Performance Characteristics of UHN-40T Unidirectional Carbon Fiber Prepreg

The UHN-40T’s performance profile is what elevates it above standard composite materials, combining a suite of properties that address the most stringent industry challenges.

First and foremost, it boasts an exceptional strength-to-weight ratio. With high tensile strength that often exceeds 3000 MPa, the UHN-40T delivers structural performance comparable to or even surpassing steel, yet it weighs up to 70% less. This transformative attribute is a game-changer for industries where weight reduction directly translates to tangible benefits: in aerospace, it cuts fuel consumption and emissions; in automotive, it boosts fuel efficiency; and in sports equipment, it enhances maneuverability without sacrificing durability. Unlike heavy metallic alternatives, components made from UHN-40T reduce overall system weight while maintaining critical load-bearing capacity, making it a preferred choice for cutting-edge engineering projects.

Durability is another standout feature of the UHN-40T. It exhibits excellent fatigue strength, enabling components to withstand millions of stress cycles—essential for applications like aircraft wings, wind turbine blades, or automotive chassis that operate under constant dynamic loads. Its superior vibration damping performance further minimizes operational noise and reduces wear on adjacent parts, extending the lifespan of entire systems. Complementing this, the prepreg has a low friction coefficient (typically below 0.15) and exceptional wear resistance, making it suitable for high-contact components such as industrial machinery parts. Additionally, it offers robust corrosion resistance, remaining unaffected by moisture, saltwater, industrial chemicals, and harsh environmental conditions that degrade metallic materials. This resistance ensures a service life that is often 2-3 times longer than traditional materials, significantly reducing maintenance costs and replacement frequency for end-users.

The UHN-40T also excels in moldability and processability. Its inherent good plasticity allows it to be shaped into any form according to precise mold designs, from simple flat panels to intricate, complex geometries with tight tolerances (as low as ±0.1mm) required for aerospace and automotive components. This flexibility integrates seamlessly with standard composite manufacturing techniques, including autoclave curing, compression molding, and filament winding. Unlike some rigid composites that demand specialized equipment, the UHN-40T can be processed using conventional machinery, lowering entry barriers for manufacturers. It maintains consistent resin content and fiber alignment during processing, reducing scrap rates to less than 5% in optimized production lines, while its easy processability cuts down on post-production refinement—saving both time and labor costs.

Product Applications of UHN-40T Unidirectional Carbon Fiber Prepreg

The UHN-40T’s unique combination of strength, moldability, and customization makes it indispensable across a diverse range of high-demand industries. Its high plasticity renders it ideal for producing core carbon fiber components, including carbon fiber tubes, carbon fiber panels, and a wide array of complex-shaped parts that would be difficult or impossible to manufacture with traditional materials.

In the aerospace industry, the UHN-40T is a critical material for manufacturing load-bearing structural components such as aircraft wings, tail fins, and cabin walls. Its 40TON modulus and lightweight properties enable a 20-30% weight reduction compared to conventional composites, directly lowering fuel consumption and carbon emissions while meeting the rigorous safety standards set by organizations like the FAA and EASA. For the automotive industry, it is a favorite among high-performance sports car manufacturers for crafting body parts such as doors, chassis, and hoods. These components not only reduce the vehicle’s overall weight by 10-15% to improve fuel efficiency but also enhance impact resistance—thanks to the material’s energy absorption capability, which is three times higher than steel—boosting passenger safety in collisions.

The high-end sports & leisure equipment sector leverages the UHN-40T’s high strength and flexibility to create premium products. Golf club shafts made with this prepreg offer 15% more flexural strength than standard carbon shafts, allowing players to generate greater swing speed and distance. Fishing rods benefit from its vibration damping, reducing hand fatigue during long casting sessions, while ski poles gain enhanced durability to withstand the harsh conditions of mountain slopes. In industrial equipment, the UHN-40T is used to manufacture pressure vessels, pipelines, and other high-pressure-resistant structures. Through advanced filament winding processes, it forms seamless components that can withstand pressures up to 10,000 psi, making it ideal for the oil and gas, chemical, and pharmaceutical industries where safety and efficiency are paramount.

Beyond these core applications, the UHN-40T excels in wind energy, where it is used in wind turbine blades ranging from 30m to 80m in length. Its high modulus ensures blade stability at high wind speeds, while its corrosion resistance stands up to coastal and offshore environments, extending blade lifespan to 25 years or more. In rail transit, it is used for lightweight, durable components like bogie frames and interior panels, reducing train weight by 10-15% and lowering energy use and track maintenance costs. It also finds use in medical equipment (such as lightweight imaging machine frames) and marine applications (like boat hulls and propeller shafts) where corrosion resistance and weight savings are critical. From aerospace innovation to everyday sports gear, the UHN-40T unidirectional carbon fiber prepreg delivers consistent, high-performance results that meet the most stringent industry demands, solidifying its status as a top-tier composite material in global markets.
