Arnet-carbon is William Barnet & Son LLC’s (Barnet, Spartanburg, S.C., U.S.) signature line of high-performance carbon fiber products, designed to meet the growing demand for lightweight, high-strength materials in thermoplastic compounding and engineered composites. With decades of experience and strong industry partnerships, Barnet has developed customized carbon fiber solutions that enhance mechanical properties while reducing overall weight across a wide range of applications.

Barnet’s product portfolio is engineered for versatility and includes oversized and chopped fibers, straight chopped fibers and milled fibers — offered in lengths ranging from 3-25 mm. Barnet says these materials are optimized for both low- and high-temperature thermoplastic composite applications and deliver a combination of tensile strength, compression strength and stiffness-to-weight ratio. Produced in North America and Europe using high-quality raw materials, barnet-carbon ensures consistent fiber quality, high-bulk density for smooth flow during processing and optimal dispersion characteristics in compounding operations.

At CAMX 2025, the company is spotlighting its oversized and chopped carbon fiber, a solution made from post-industrial recycled material. Engineered specifically for thermoplastic compounding, this product is designed to provide high mechanical reinforcement while aligning with sustainability goals. To support a wide range of polymer systems, Barnet applies custom thermoplastic sizings tailored to the compound matrix — ensuring optimal compatibility, dispersion and performance. Whether the application requires enhanced flow, increased strength or better surface finish, Barnet says its oversized and chopped fibers provide an adaptable, eco-conscious reinforcement solution.

Barnet’s capabilities extend well beyond carbon fiber. As a global supplier of synthetic fibers, yarns and polymers, the company serves a wide range of industries including automotive, industrial, protective apparel, home furnishings and more. Its vertically integrated operations, global manufacturing footprint and technical expertise enable its team to support innovation and sustainability across complex applications and supply chains.
