Abstract
Self- healing is the ability to repair damage in an automatic and specific fashion without manual intervention.
If humans plan to travel far into space and to planets, new advanced technologies will be required for the construction of spacecrafts. One weakness of current materials used for construction is that they form hairline cracks, which causes massive damage over a long period of time.
Damage begins as tiny surface cracks which are invisible to the naked eye. These cracks grow until the material weakens and cracks.
In 2001, researchers at university of lllinios developed a new synthetic material that will heal itself when cracked or broken. This material can be used for constructing spacecrafts, which can traverse millions of miles without incurring any damage.

SELF-HEALING SPACECRAFT

INTRODUCTION

What IS self-healing Spacecraft?
It is related to human’s body self repairing system.
Biomimetic self-healing repair system.

CONCEPT OF SELF-HEALING MATERIAL

Composite material.
Microencapsulated healing agent.
Catalyst.
This composite material will heal itself when crack is formed on it’s surface.

CONSTRUCTION OF SELF-HEALING SPACECRAFT USING SELF HEALING CONCEPT

In April 13, 2006 Jean M. Hoffman Aerospace engineers are on the cusp of developing composites that can repair themselves.
Hollow fibers are used (40 microns in diameter).
Hollow fibers are filled with adhesive like repair agent i.e. Epoxy resin.

DETAILED STUDY OF SELF-HEALING MATERIAL

In composite material, fatigue and impact damage can lead to matrix cracking.
Biological materials is their ability to automatically heal when they are damaged. This is achieved by hierarchical structuring.
The released composite undergoes a chemical
reaction or polymerization.

LIMITATIONS OF SELF-HEALING SPACECRAFT

The main limitation of self healing spacecraft is that they can heal thyself only for hairlines or micro thin cracks. They can’t heal themselves for large damages.
The self healing material used for spacecraft cannot repair damage after lying dormant.

CONCLUSION

The self-healing repair of space composite structures has identified the following conclusions:
The hollow filaments were successfully infused with epoxy resin and hardener.
For the self-healing repair of laminate surface damage, two different activation methods could be employed, i.e. UV curing and the absence of oxygen.
Hollow filaments have been successfully manufactured with an external diameter of 60μm with 50% hollowness.
