A recommended guideline for how to work with te xtreme spread tow fabrics

  1. 1. A recommended guideline for how towork with TeXtreme® Spread Tow Fabrics
  2. 2. This guide will aid in learning to use TeXtreme®Spread Tow Fabrics effectivelyTeXtreme® Spread Tow Fabrics are based on Oxeons Tape Weaving Technology that uses tapesinstead of yarn. In any given area more fibers can be packed in tape form than in a yarn. Awoven material comprising interlacing fibrous tapes, instead of yarns, displays a substantiallyreduced number of interstices/openings. This means that a tape woven structure presents lessaccumulation of matrix at the interstices and hence increased fiber volume fraction.
  3. 3. Tools to be used in this guide: Hairdryer, lamination tool, knife,scissors.
  4. 4. Take advantage of the distinct lines seen through release film whenlaying the patterns at 0-, 90- and +/-45 or other ply orientations.
  5. 5. Use tool surfaces that are polished and release agents with relativelyhigh degree of slip.
  6. 6. Start with a +/-45 ply if possible which makes draping in the sharpcorners easier with less spring back. Choose initial starting pieceaccording to internal layup procedure/standard.
  7. 7. Start at the tightest section working towards larger less complicatedareas.
  8. 8. Work along 45-degree direction and soften the resin by using a hairdryer or heat gun to allow the fabric to scew.
  9. 9. Use helping aids at tight corners, do not use any sharp metal objects.Bridging needs to be addressed to assure good definition in corners.
  10. 10. Make sure to evacuate all air before debulking so no air bubbles arepresent (highlighted section in the image).
  11. 11. Cut darts at complex geometries to avoid folds/creases.
  12. 12. Cut away excessive material to allow consolidation at all corners. Thishelps in reducing the risk of bridging.
  13. 13. Always debulk the fist ply! Perforated release film is recommendedduring this step due to the dense nature of TeXtreme®.
  14. 14. Follow standard bagging techniques. To maintain consistent vacuumpressure, the breather should cover the entire laminate.
  15. 15. The vacuum valve should be positioned outside of the laminate with abreather connection to maintain vacuum flow.
  16. 16. Ensure that the bag is not bridging at any corners, be careful not tocause a tear or puncture of the bag.
  17. 17. Envelope bag the tool when possible to avoid tool leakage leading topoor air evacuation.
  18. 18. Vent possible bubbles to avoid trapping air at tool surface using needleor similar being careful not to scratch the mold surface.
  19. 19. Start 2nd ply using the same sequence as the first, making darts whereneeded.
  20. 20. By using a hair dryer or heat gun the TeXtreme® fabric can be scewedwhere needed (highlighted in the image above).
  21. 21. Stagger ply drop-offs at stiffened sections. There is no need torepeatedly debulk unless six layers or more are being used orotherwise recommended by prepreg manufacturer(s).
  22. 22. Use release films recommended by the prepreg manufacture(s).
  23. 23. Follow standard bagging procedure.
  24. 24. Use thermocouple that measures the temperature at the tool and notin the air. Following the prepreg manufactures cure cycle is importantto achieving a high quality surface smoothness.
  25. 25. Some resin will bleed, as normal for fiber reinforced composites.
  26. 26. Demold the part. Notice well defined tight corners with no bridging onthe relatively complex geometry of the finished part.
  27. 27. An ultra light composite has now been produced.www.oxeon.se | contact@oxeon.se | +46 33 20 59 70
