Impact damage resistance

The 2020 Samos, M7.0 earthquake was characterized by an unusual bi-modal-type distribution of damage: limited damage in the nearfield (especially northern Samos coast) and serious localized damage in multi-story buildings in the far field (İzmir area). This pattern is not consistent with the typical distribution of isoseismal lines, and it seems not to represent an isolated effect; the 2014 Samothraki- Gökçeada M6.9 earthquake, for example, may in fact represent a parallel, though at smaller scale.

In this study, the impact response of glass/epoxy laminates interleaved by Polycaprolactone (PCL) nanofibers is considered. PCL is a thermoplastic polymer, which is a good choice for toughening epoxy-based composite. The impact tests were conducted on curved laminates and under 24 and 36J.

Variation of the impact characteristics such as maximum contact load, maximum deflection, maximum contact time, absorbed energy are depicted in the figures. The results showed that PVDF nanofibers are not a good choice for toughening epoxy and improving impact damage resistance of GFRP.
