  2. Content • NPSP Composites • NaBasCo • Optimization NaBasCo  Conclusion

  3. NPSP Composites

  4. Established in 1998 • Around 25 employees • Thermosetting composites • Some customers: • Nedtrain, ANWB, G-Star,

  5. Products NPSP Composites

  6. Production process Vacuum Assisted – Resin Transfer Moulding

  7. Options NPSP Composites • Transparent resins • Different kinds of fibres possible • Integration of LEDs • Use of inserts • Details on all sides • Double shaped curves • Elegant products

  8. Mission NPSP Composites ‘It is our mission to make sustainable composites common ground.’ Fibres Resins  

  9. Nature Based Composites

  10. NaBasCo

  11. Nature Based Composites

  12. Nature Based Composites • NaBasCo is: • Natural fibres: flax, hemp • Resins: polyester • Sandwich material & additives

  13. Current situation • Current reasons to apply natural fibres: • Weight • Price • Acoustics • Radiance permeability • Health and safety in processing • Esthetics • Sustainability

  14. Current situation • Non-wovens • No optimization fibres for use in composites  Hands on approach

  15. Current situation • Consequences: a lot of uncertainties • What about: fire resistance, moisture sensitivity, lifetime, etcetc.

  16. Optimization NaBasCo

  17. Potential natural fibres Mechanical properties

  18. Optimization NaBasCo • Mechanical properties • Current optimization steps: • Use of wovens and unidirectional mats

  19. Optimization NaBasco • Mechanical properties • Current optimization steps: • Low-torque yarn or direct use of sliver: • Twining results in reduction of tensile strength • of at least 10%

  20. Optimization NaBasco • Mechanical properties • Current optimization steps: • Lower moisture content of natural fibres • Moisture content natural fibres around 10%. • Influence drying on mechanical properties: • E-modulus: 60% higher • Tensile strength: 25% higher

  21. Optimization NaBasco • Mechanical properties • Other possible optimization steps: • Use of sizings to improve adhesion resin-fibres • Thermal modification of natural fibres • Other natural fibres • Besides mechanical properties: • This year official tests on: fire resistancy, • moisture absorption and uptake, aging,… • Further “greening” of NaBasCo:

  22. Optimization NaBasCo Potential fully bio-based composites The next step: also bio-based resins.  A few resins on the market;  25%-100% bio-based;  Not all fit for VA-RTM: viscosities, high curing temperatures (>140 degrees);  Compatibility with natural fibres limited: moisture sensitivity, aggressive.

  23. Conclusion

  24. Conclusion • NaBasCo shows a lot of potential: • UD flax already show mechanical properties • comparable (or higher) to that of glass non- • woven. • Fully bio-based composites are proven to be • feasible in the future

  25. Conclusion • Optimizations and development are needed: • Optimization of processing of natural fibres • for use in composites; • Optimization of natural fibre reinforced • composites; • Towards fully bio-based composites (bio-resins!); • Chain & market development.
