Carbon fabric 245 g/m² (style 462 Aero, twill weave), width 100 cm

Style 462 Aero is manufactured from Tenax® HTA 40 or Pyrofil™ TR30S carbon fibres to specification WL 8.3611 and complies with aerospace fabric specification DIN 65147 / WL 8.3522. The 2/2 twill weave with 6 ends/cm in both warp and weft allows good conformity to curved component contours. At 245 g/m², the fabric provides a high fibre mass per ply for efficient laminate build-up.

Technical data

Typical applications

• Structural and fairing components for aircraft, subject to component-specific approval
• Fuselage shells, wing components and fairings for model aircraft and UAVs
• Body panels and air ducts for motorsport and automotive applications
• Boatbuilding, marine applications and lightweight sports equipment
• Sandwich skins, CFRP shells and technical moulded parts
• Technical housings and visible carbon components with a twill pattern

Properties and processing

The 2/2 twill weave has fewer yarn interlacings than a plain weave, allowing the fabric to conform more easily to radii, curved mould surfaces and complex component geometries. The balanced yarn count provides reinforcement in both principal fibre directions. Its diagonal twill pattern also makes it suitable for high-quality visible carbon surfaces.

Epoxy laminating resin systems with good fibre wet-out characteristics are suitable for high-quality CFRP laminates. Maintain accurate fibre alignment during cutting and lay-up, as twill fabrics may be prone to yarn displacement. Complete resin impregnation and careful air removal are particularly important in multi-ply laminates.

The ECC data sheet provides mechanical test results for press-moulded reference laminates with 50% fibre volume fraction at room temperature, manufactured according to WL 5.3200. Typical values are 820 MPa tensile strength, 635 MPa compressive strength, 795 MPa flexural strength and 71 MPa interlaminar shear strength (ILSS). These values apply to the tested reference laminate and are not guaranteed properties of arbitrary finished components.

Material selection

For applications without a specified aerospace material requirement, the 245 g/m² twill-weave carbon fabric (CT-245100T) is available as an alternative. Style 462 Aero additionally provides a defined aerospace material specification to DIN 65147 / WL 8.3522. Applications requiring formal approval must also meet the relevant material documentation, resin system and component approval requirements.
