FEATURE / SYNTHETIC EPOXY FOAM
Figure 8. Stress-strain curve of a double layer capsules filled
foam in the first three loading cycles and the optical microscopic images on the surface of foams.

CONCLUSIONS
Though the development of double layer capsules-based self-healing system, 1st recovered
elastic modulus of epoxy foams reaches 96.7%
compared to that of intact material. Furthermore, multiple cycles of healing effects have been
achieved and cracks have been healed based on
proposed self-healing system.
