TEXTREME Applications: From Aerospace to Sporting Goods

How TEXTREME Technology Is Changing Lightweight Composite DesignTEXTREME, developed by Toho Tenax, is a unidirectional (UD) carbon fiber tape material designed to improve the performance, manufacturability, and design freedom of composite structures. By combining ultra-high-modulus carbon fibers with a thin, heat-stable binder and precision-cut tape formats, TEXTREME enables engineers to produce lighter, stronger, and more efficient components across aerospace, automotive, sporting goods, and other high-performance industries.

This article explains what TEXTREME is, how it differs from traditional composite reinforcements, the manufacturing methods that exploit its strengths, the design and performance advantages it brings, key industry applications, limitations and considerations, and future directions.

What is TEXTREME?

TEXTREME is a family of unidirectional carbon fiber tapes that are delivered in a tape or ply format rather than woven fabric. Key characteristics:

• Unidirectional fiber alignment that provides excellent axial stiffness and strength.
• Thin, low-mass resin-compatible binder that holds fibers in place for automated handling and compaction but minimally interferes with fiber packing.
• Wide tape widths and various tow sizes that allow designers to lay fibers precisely where needed.
• High fiber volume fraction potential, enabling improved specific strength and stiffness versus some traditional laminates.

Because fibers arrive already aligned and in tape form, TEXTREME reduces the need to cut and realign tows from larger fabrics or to stitch/braid complex shapes, simplifying the creation of optimized, load-path-oriented laminates.

How TEXTREME differs from traditional reinforcements

Traditional composite reinforcements include woven fabrics, multiaxial stitched fabrics, and prepregs. TEXTREME contrasts with these in several important ways:

• Fiber orientation

  • Woven fabrics keep fibers interlaced, which improves drape and reduces local fiber waviness but introduces crimp (fiber undulation) that reduces in-plane stiffness.
  • TEXTREME’s UD tapes keep fibers straight and aligned, maximizing stiffness and strength along the fiber direction.

• Fiber packing

  • Woven and stitched fabrics often limit achievable fiber volume fractions due to resin-rich areas and architecture-related voids.
  • TEXTREME allows higher fiber volume fractions and denser packing because fibers are laid in thin, well-controlled tapes.

• Tailoring and placement

  • Cutting, stacking, and trimming woven plies can waste material and limits fine-tuned tailoring.
  • TEXTREME tapes can be placed with high precision, enabling load-path-driven design and material minimization.

• Manufacturing compatibility

  • TEXTREME is compatible with a range of processes: autoclave prepregs, out-of-autoclave (OOA) curing, resin infusion (VARI), compression molding, and automated tape laying (ATL)/automated fiber placement (AFP) style operations adapted for tapes.
  • Its thin binder reduces tackiness and allows good consolidation during cure.

Manufacturing methods that leverage TEXTREME

TEXTREME is versatile across processes. Common approaches include:

• Automated and semi-automated tape placement

  • Wide UD tapes can be laid rapidly with accurate fiber orientation control, reducing lay-up time and human error.

• Hand lay-up and manual ply placement

  • For low-volume or complex shapes, manual placement of narrow TEXTREME tapes allows designers to follow complex load paths precisely.

• Resin infusion and vacuum-assisted resin transfer molding (VARTM)

  • TEXTREME tapes can be stacked and infused; their high permeability (compared to densely woven fabrics) eases resin flow in some configurations.

• Compression molding and hot-molding

  • Preforms of TEXTREME tapes can be consolidated under heat and pressure into complex shapes with thin cross-sections and high fiber content.

• Prepreg-style processing

  • TEXTREME products with compatible resins can be used in prepreg workflows for high-performance aerospace parts.

These methods enable quicker cycle times, fewer defects from fiber waviness, and parts with higher specific properties.

Design and performance advantages

1. Higher specific stiffness and strength

   • By minimizing fiber crimp and maximizing fiber volume fraction, TEXTREME laminates achieve superior stiffness-to-weight and strength-to-weight ratios compared with many woven alternatives.

2. Load-path-driven material placement

   • Designers can place fibers exactly where loads demand them (e.g., along stiffeners, edges, stress concentrations), reducing unnecessary material and weight.

3. Reduced part count and assembly complexity

   • Integrating load-carrying fibers into single-piece preforms reduces the need for mechanical fasteners, adhesives, or secondary joining components—cutting assembly mass and potential failure points.

4. Improved fatigue performance

   • Straight, continuous fibers aligned with primary load directions tend to improve fatigue life, as there are fewer matrix-rich areas and fewer local stress concentrations from fiber waviness.

5. Better control over anisotropy

   • TEXTREME’s precision placement allows engineers to tailor anisotropy—stiff where needed, flexible where permitted—optimizing structural efficiency.

6. Surface finish and thin-walled parts

   • The tape’s thinness and ability to conform to molds help produce thin-walled, high-quality surface finishes useful for aerodynamic components and consumer-facing parts.

Typical applications and industry impact

• Aerospace

  • Primary and secondary structures where weight savings directly reduce fuel burn and emissions: UAVs, airframe components, fairings, control surfaces, and interior structural parts.
  • Satellite and space structures benefit from high stiffness and low mass.

• Automotive and motorsport

  • Structural chassis components, crash-optimized parts, body panels, and bespoke performance parts where weight reduction improves efficiency and handling.

• Sporting goods

  • High-performance bicycles, rackets, skis, and paddles where stiffness-to-weight and tailored flex are prized.

• Marine

  • Lightweight hulls, masts, spars, and performance sailing components that need high stiffness and fatigue resistance.

• Industrial and energy

  • Wind turbine blades (sections or reinforcements), robotic arms, and tooling where tailored stiffness and reduced mass improve performance and reduce operating costs.

Limitations and design considerations

• Out-of-plane properties

  • UD tape laminates can be weaker in through-thickness directions unless addressed (e.g., using z-pinning, through-thickness stitching, thin cross-plies, or secondary bonding).

• Handling and placement on complex doubly-curved surfaces

  • While tapes can conform well, extremely compound shapes may require smaller tape widths or hybridization with woven materials to avoid bridging and wrinkles.

• Cost

  • High-performance UD carbon tapes can be more expensive per kilogram than commodity woven fabrics; cost-benefit must be evaluated against lifecycle performance gains.

• Resin compatibility and process qualifications

  • Parts intended for aerospace often require rigorous material/process qualification; TEXTREME-based systems must be qualified for the intended resin system and manufacturing route.

• Joining and repair

  • Repair processes and joining strategies can differ from woven-fabric parts; engineers must plan for field repairability and bonding.

Design examples and practical tips

• Use wider tapes for large, flat or gently-curved panels to speed layup; switch to narrower tapes near cutouts, edges, or highly curved areas.
• Combine TEXTREME UD tapes with thin off-axis plies or lightweight woven skins to improve transverse strength and impact resistance.
• For highly-loaded stiffeners, align multiple passes of UD tape along the stiffener run rather than relying on quasi-isotropic laminates—this yields dramatic weight savings.
• When designing for resin infusion, design resin flow channels and consider breakable flow media between tape bundles to ensure even impregnation.
• In fatigue-critical parts, orient fibers to avoid abrupt changes in ply angle at load-transfer regions; gradual steering of tape paths minimizes ply-drop stress concentrations.

Future directions

• Automated Fiber Placement (AFP) adaptation: further integrating TEXTREME-style tapes into high-speed AFP machines with active steering will expand manufacturing throughput for large structures.
• Hybridization: combining TEXTREME with new thermoplastic matrices, metallic inserts, or nanomaterial interleaves to improve damage tolerance and recyclability.
• Sustainable composites: development of recyclable resin systems and reuse-friendly binders that preserve TEXTREME’s handling benefits while improving end-of-life options.
• Electromechanical multifunctionality: integrating conductive fibers or printed electronics with TEXTREME tapes to add sensing, de-icing, or EMI-shielding capabilities.

Conclusion

TEXTREME technology shifts composite design from architecture-driven compromises toward highly optimized, load-path-oriented laminates. By delivering straight, high-fiber-fraction UD tapes in manufacturable formats, it enables lighter, stiffer, and more efficient structures across aerospace, automotive, sports, marine, and industrial sectors. Designers must still balance out-of-plane properties, cost, and manufacturability, but when applied thoughtfully, TEXTREME can materially improve structural performance and open new possibilities in lightweight composite design.
