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.
