Microcapsules containing epoxy resin EPON 862, phenyl acetate solvent, and multi-walled carbon nanotubes were fabricated by in-situ polymerization for the development of a self-healing composite. The microcapsules were embedded in an epoxy matrix in single-edged notch bend shapes for fracture testing on a three-point bend test fixture. Healing efficiency was calculated for specimens with various microcapsule loading ratios. Fracture tests confirmed healing ability with the microcapsules. Preliminary results indicated higher healing efficiencies with increased microcapsule loading.
