Description
Carbon fiber UD fabrics are high-performance composite reinforcement materials with all fibers aligned in a single direction, delivering targeted directional mechanical properties for advanced composite structure manufacturing. This product series adopts PAN-derived 12K carbon fiber as the core raw material, with the CUD200-450 as the standard specification widely specified for automotive and industrial component production. The unidirectional fiber layout enables targeted strength reinforcement along the load-bearing axis, serving as a standard reinforcement layer for composite parts. Produced via a weaving process, the fabric supports adjustable specifications to fit diverse commercial procurement needs across multiple industrial sectors.

The standard CUD200-450 model features a 450mm width and 200g/m² surface density, supplied in 50m or 100m per roll. For tailored commercial procurement needs, fabric weight is adjustable within 150g/m² to 1400g/m², and width ranges from 100mm to 1650mm to match specific production line configurations and component dimensions.
Manufacturing
The production workflow follows three core stages.
First, PAN-based carbon fibers are selected as the primary reinforcement material, designed to pair with common matrix resins including epoxy resin, polyester resin and phenolic resin.
Second, fibers are aligned in a uniform 0° direction and formed into a stable unidirectional structure via weaving processing, ensuring consistent fiber orientation across the full fabric width.
Third, the fabric is engineered for standard composite fabrication workflows: after resin impregnation to achieve full fiber wet-out, it can be cured via heat and pressure processes such as press molding, vacuum infusion and autoclave curing to form finished composite parts.
Application Area
Composites reinforced with this UD fabric have a tensile strength above 3500 Mpa, 7 to 9 times that of steel, with a tensile modulus ranging from 230 Gpa to 430 Gpa. Carbon fiber has a density less than one quarter that of steel, enabling significant component weight reduction without sacrificing load-bearing capacity. The material also demonstrates high temperature resistance, corrosion resistance and thermal stability under standard operating conditions.

Maintenance
For surface care, remove dust and stains promptly during use with designated cleaning agents; avoid acidic or alkaline cleaners that may damage fiber surfaces. Avoid prolonged exposure to direct sunlight, as extended UV exposure can cause surface cracking and fading that reduces service life. Store the fabric in dry, ventilated conditions, away from high humidity and high temperature environments to preserve material performance. Regular surface inspections are recommended during use to identify potential damage at an early stage.
 | Clean the surface of the carbon fiber Fabric. During use, dust and stains on the surface of carbon fiber Fabric should be cleaned in time, and special cleaners should be used to avoid acidic or alkaline cleaners. |
 | Prevent carbon fiber Fabric From being exposed to sunlight for a long time. Long exposure to sunlight will make the surface of carbon fiber Fabric crack and fade, affecting the beauty and service life. |
 | When storing carbon fiber Fabric Attention should be paid to avoid humidity, high temperature and other environments. When storing carbon fiber Fabric, avoid humidity, high temperature and other environments, and keep dry and ventilated. |
