  1. Self-healing materials Multidisciplinary project group 2

  2. Self-healing materials • Introduction • Concepts: • Encapsulated healing agent • Remendable cross-links • Interdiffusion • Biomimetic approach • Opportunities • How to continue

  3. Introduction • Is it feasible to create a self-healing material? • Application?

  4. Self-healing materials • Introduction • Concepts: • Encapsulated healing agent • Remendable cross-links • Interdiffusion • Biomimetic approach • Opportunities • How to continue

  5. Concepts: Encapsulation Autonomic healing After reaction it is over

  6. Concepts: Remendable cross-links • Diels Alder • U-py • Metal Complex • Combinations

  7. Concepts: Remendable cross-links • Diels Alder • U-py • Metal Complex • Combinations

  8. Concepts: Remendable cross-links • Diels Alder • U-py • Metal Complex • Combinations

  9. Concepts: Remendable cross-links • Diels Alder • U-py • Metal Complex • Combinations • Multiple healing • Possibilities  Not autonomically

  10. Concepts: Interdiffusion  Only amorphous polymer Competition between interdiffusion and crosslink Very slow

  11. Biomimetic approach Autonomic healing It’s over when fibre breaks

  12. Biomimetic approach Controlled release of growth-factors  Hydrogel instead of microcapsules  Site specific  How to detect a crack?

  13. Self-healing materials • Introduction • Concepts: • Encapsulated healing agent • Remendable cross-links • Interdiffusion • Biomimetic approach • Opportunities • How to continue

  14. Opportunities • Microcapsules: finetuning • Interdiffusion: Low Tg Polymers • Biomimetic: Unbreakable porous hollow fibres. • Remendable Crosslinks: Dye a U-py

  15. Self-healing materials • Introduction • Concepts: • Encapsulated healing agent • Remendable cross-links • Interdiffusion • Biomimetic approach • Opportunities • How to continue

  16. Focus: • Cross-links with dyes • Detection systems

  17. Why Dye? • Present research: a fluorescent dye on U-py • Our idea: Energy dissipating dye! • Also possible for Diels-Alder crosslinks

  18. Detection Microcapsules detect – repair – capsule broken Crosslinks repair – repair again  Weakest point multiple-healing-systems: no detection

  19. Piezo elements
