What is it about?
The failure of FRPs is complex and its behaviour depends on many factors. We have shown that even low energy impact associated with small percentage of absorbed water can significantly reduce the flexural performance of composites. we have also found that removing the absorbed water by drying can improve the properties but this needs more investigation.

Why is it important?
Our findings gives detailed information about the failure mechanisms in this type of composites when subjected to various conditions, and it shows that it is possible to improve the properties by reversing the effect of water.
Perspectives
Working on this project/article was a great pleasure as it has team members with whom I have had long standing collaborations. This article also leads to more collaborations with composites manufacturers and opens door to a greater involvement in studying and predicting the performance of damaged composites.
