245 g/m² 3K Twill Carbon Fiber Fabric

245 g/m² 3K Twill Carbon Fiber Fabric

245 g/m² 3K Twill Carbon Fiber Fabric is a woven carbon fiber reinforcement material designed for composite laminate manufacturing. Featuring a nominal areal weight of 245 g/m² and a twill weave construction, the fabric consists of 3K carbon fiber tows arranged in the warp and weft directions, providing bidirectional reinforcement.

The 3K designation indicates that each carbon fiber tow contains approximately 3,000 individual filaments. Carbon fibers are widely used in composite applications where low weight and high specific mechanical properties are required. The mechanical performance of the finished laminate depends on the fiber grade, resin system, laminate construction, and manufacturing conditions.

Twill Weave Construction

Twill weave is a textile construction characterized by a diagonal pattern formed by the interlacing of warp and weft yarns. Compared with plain weave fabrics, twill constructions generally offer improved drapability, allowing the fabric to conform more easily to curved and complex mould surfaces.

The distinctive diagonal carbon fiber pattern also makes twill fabrics suitable for composite components where a visible carbon fiber surface is desired in addition to reinforcement.

Applications

245 g/m² 3K twill carbon fiber fabrics are used in composite panel and component manufacturing, marine applications, sporting equipment, aerospace-related composite components, robotic systems, modelling, prototyping, and custom engineering projects.

The characteristic woven carbon fiber appearance also makes the fabric suitable for decorative composite surface applications. Suitability for specific structural or safety-critical components must be assessed according to the material specifications and design requirements.

Composite Manufacturing

Carbon fiber fabric is combined with a suitable resin system to form the reinforcing layers of composite laminates. Fabric orientation, number of layers, and resin selection depend on the intended component geometry and required mechanical properties.

Resin compatibility may vary depending on the surface treatment and sizing of the carbon fibers. The relevant material technical data sheets should be consulted before selecting a resin system and processing conditions.
