Technology

TeXtreme® Spread Tow carbon reinforcements are using spread tows to produce optimized reinforcements for ultra light composites.

Spreading tows (yarns) into very thin tapes enables reinforcements in woven structure as well as unidirectional tapes with mechanical performance and possibility for weight savings that are unique compared to conventional reinforcements.

 


SPREADING CARBON FIBER TOWS INTO TAPES

The Spread Tow UD tapes produced are much thinner than conventional carbon fiber tapes and have more material packed in the same area which gives better mechanical performance.

These Spread Tow tapes are then used as they are as local reinforcements etc. or used to weave the novel TeXtreme® Spread Tow fabrics.

The patented TeXtreme® Spread Tow fabrics are then used by companies manufacturing composite products found in: bicycles, Formula 1, NASCAR, surfing, golf shafts, ice hockey, aerospace, industrial and Americas Cup.

The ply thickness of each separate layer is clearly connected to the strength of the composite part. The benefit from using thin TeXtreme® Spread Tow reinforcements when looking at the apparent strength is illustrated above.

Combining the weight savings possible from the optimal fiber structure with the thin nature of Spread Tow reinforcements renders a performance that no other composite reinforcement can match.

 


layup time savings

By using TeXtreme® Spread Tow carbon fabrics one opens up possibilities to save money and time in the manufacturing of the composite parts.

Due to TeXtreme® being balanced in already in one ply one can achieve savings in both the use of material and reducing the lay-up time through using fewer plies and still be able to achieve a symmetrically balanced laminate.

benefits

  • Weight savings
  • Increased stiffness
  • Improved impact tolerance
  • Superior surface smoothness
  • Reduced labor costs
  • Increased strength

 

FLEXIBILITY

TeXtreme® is available in a wide variety of configurations. TeXtreme® Spread Tow fabric is manufactured using TeXtreme® Spread Tow tapes and its construction can be optimized by interlacing the dry UD tapes in different angles +α/-β and through combination of different fiber types and materials.

 

Product categories:

  • 0/90
  • +45/-45
  • UD tapes
  • Hybrids

 

Optimization variables:

  • Areal weights
  • Fiber type
  • Fiber angle
  • Fiber distribution
  • Tape width
  • Fabric width
