Abstract
The present invention generally relates to self healing polymer materials comprising thermoset and thermoplastic polymers. The present invention also relates to a method of manufacturing self healing polymer materials, methods of post-curing and healing the self healing polymer materials, composite materials comprising self healing polymer materials and methods of preparing the composite materials. In an attempt to develop improved structural materials, polymers and polymer materials have been identified that can be used in materials to act as self healing agents to repair structural damage occurring in the materials. The self healing polymer materials that have been identified are capable of being healed under post-curing or healing conditions.
