Abstract
This paper lays out a technique whereby delamination growth in a GFRP panel
subjected to a low velocity impact is compartmenatlised using discrete thermoplastic
film rings. By comparing the compartmentalised configurations with an unmodified
baseline panels the thermoplastic film rings have been shown to suppress delamination
crack growth at the desired interfaces and effectively prevented any growth beyond
the outer diameter of the rings. This has resulted in the reduction of the damage
footprint areas by up to 38% and an improved compression after impact (CAI)
strength of up to 18% relative to a baseline panel.
