    1 : SELF HEALING MATERIALS SUBMITTED BY UMAPADA DASH 4TH SEM ETC Technical Seminar Presentation on
    2 : INTRODUCTION MOTIVATION RESEARCH MECHANISM 4.1 WHAT ARE THE COMPONENTS 4.2 PICTORIAL MECHANISM MINIMAL AND IDEAL SELF-HEALING APPLICATION ACKNOWLEDGEMENT
    3 : Self Healing Materials(SHM) are SMART materials. They detect micro cracks and repair them automatically. As a result they lengthen the lifetime and the reliability of materials.
    4 : At cryogenic temperatures, very small cracks are formed in spacecrafts. There is no detection of these cracks. Repairing is also not possible. As a result the spacecraft undergoes severe damage over time. SHMS can overcome this problem.
    5 : SHM’s remain to be the most sought after research area. In February 2001,researchers at the university of Illinois at Urbana Champaign announced development of SHM’s for spacecrafts. In October 2004,the Dutch government defined “High tech systems and materials” as one of the focal points for innovation.
    6 : SHM’s are biologically inspired. They sense damage and repair. There are 3 parts to SHM’s: 1>Composite material 2>Microencapsulated healing agent 3>Catalyst

    9 : Minimal Self Healing Material Ideal Self Healing Material Repairs damage partially Repairs damage only once. Repairs damage by external triggers. The self healing material has properties inferior to existing materials Is expensive - Repairs damage completely. - Repairs damage an infinite number of times - Repairs damage autonomously - The material has comparable or better properties than existing material - Is cheap
