VOLSUN
As a leading supplier of high-performance composite materials, VOLSUN presents our premium unidirectional carbon fiber fabric, a lightweight, ultra-strong reinforcement material engineered for automotive manufacturing, structural engineering, aerospace, and high-performance sports equipment production. Made from high-strength virgin carbon fiber yarn (≤12k), this unidirectional fabric delivers exceptional tensile strength (more than 5 times that of steel of the same weight) with a density of just 1/5 of steel, making it the ideal material for industrial clients seeking to optimize strength-to-weight ratios in their products and projects. Available in standard 200g/㎡ and 300g/㎡ specifications, it is designed for use with specialized carbon fiber impregnating adhesive to deliver consistent, reliable reinforcement performance.
At the core of our unidirectional carbon fiber fabric cloth is its exceptional mechanical performance, with a tensile strength of ≥3400MPa, elastic modulus of 230GPa, and flexural strength of ≥700MPa, tested to GB3354-2014 standards. This ultra-high strength, paired with its ultra-lightweight composition, enables industrial clients to achieve significant weight reduction without compromising structural rigidity and load-bearing capacity. For automotive manufacturers, this translates to improved vehicle energy efficiency, enhanced acceleration and braking performance, and reduced carbon emissions, while for structural engineering projects, it delivers superior reinforcement without adding excessive load to existing structures.
Our carbon fiber fabric cloth features excellent flexibility, making it adaptable to complex structural shapes including beams, columns, walls, curved surfaces, and irregular automotive components, with no restriction on structural geometry. It delivers outstanding chemical corrosion resistance, high and low temperature stability, and X-ray translucency, making it suitable for use in harsh industrial, outdoor, and chemical environments. Its unidirectional fiber design ensures concentrated tensile strength along the fiber axis, enabling precise, targeted reinforcement for high-stress areas in automotive parts, building structures, and industrial equipment.
This carbon fiber fabric for automotive parts is designed for easy, efficient installation, with a thin, uniform thickness (0.167mm per layer for 300g/㎡ specifications) that minimizes finished part size and structural profile. It is compatible with standard resin impregnation and wet lay-up processes, supporting both manual installation and automated production lines for high-volume manufacturing. With interlaminar shear strength ≥45MPa, it delivers excellent bonding performance with resin matrices and base materials, ensuring long-term, stable reinforcement performance with no delamination or degradation over the service life.

Our unidirectional carbon fiber fabric delivers targeted solutions for industrial clients across high-demand sectors:
Automotive Lightweight Manufacturing: Production of automotive body panels, chassis components, interior structural parts, and racing vehicle components, delivering significant weight reduction while enhancing vehicle rigidity, torsion resistance, and crash safety performance.
Building & Infrastructure Reinforcement: Seismic reinforcement, load-bearing capacity upgrade, and crack repair for bridges, tunnels, commercial buildings, and industrial structures, providing a cost-effective, non-intrusive alternative to traditional steel reinforcement.
Aerospace & Aviation Engineering: Manufacturing of aircraft interior components, UAV airframes, and satellite structural parts, leveraging its ultra-lightweight, high-strength properties to improve payload capacity and flight performance.
High-Performance Sports Equipment: Production of bicycle frames, golf club shafts, sailing equipment, and winter sports gear, enabling optimized weight distribution and enhanced mechanical performance for professional and recreational products.
VOLSUN works closely with industrial partners to deliver customized unidirectional carbon fiber fabric solutions aligned with unique project and production requirements. We offer customizable specifications including fabric weight (200g/㎡, 300g/㎡, and custom grades), width (100mm to 500mm, and custom sizes), yarn count, and warp yarn density, to match specific application needs. Our flexible supply chain supports both small-batch prototype orders and large-volume bulk shipments, with reliable lead times and global delivery capabilities to support manufacturing and construction operations worldwide.
Our carbon fiber fabric cloth is designed for use with specialized carbon fiber impregnating adhesive, including epoxy resin systems, which are recommended to achieve optimal bonding performance and mechanical properties.
The 300g/㎡ high-strength grade is the standard choice for automotive structural components, while 200g/㎡ grade is suitable for non-structural lightweight parts and complex curved surfaces. Our technical team can provide tailored recommendations based on your specific performance requirements.
When stored in a cool, dry environment away from direct sunlight and moisture, the unidirectional carbon fiber fabric has a shelf life of 12 months from the date of manufacture.
