Improvement of fatigue resistance of epoxy composite with heterogeneous solidstate self-healing system

The purpose of this research study was to investigate the improvement in fatigue life parameters and static strength residues of heterogeneous solid-state of the self-healing resin after exposure to fatigue cycles. The healing system is based on the thermoplastic-thermosetting semi-interpenetratin...
