Fibre optic sensors for impact-induced damage detection and assessment in composite materials

Fibre optic sensors for impact-induced damage detection and assessment in composite materials
Low velocity impact (LVI) is considered potentially dangerous for a composite structure mainly because the damage, in the form of delaminations and matrix cracking, is created within the laminate or near the back face and might be left undetected. Most of the conventional damage assessment techniques require the composite structure or component to be taken out of service. A novel in-situ damage monitoring system using embedded fibre optic sensors was employed to study LVI and to perform impact damage assessment together with an instrumented falling dart impact tester.

Abstract

Low velocity impact (LVI) is considered potentially dangerous for a composite structure mainly because the damage, in the form of delaminations and matrix cracking, is created within the laminate or near the back face and might be left undetected. Most of the conventional damage assessment techniques require the composite structure or component to be taken out of service. A novel in-situ damage monitoring system using embedded fibre optic sensors was employed to study LVI and to perform impact damage assessment together with an instrumented falling dart impact tester. In this study, the impact energy varied by adjusting the drop heights.
