Abstract

Fiber optic phase shifting Electronic Speckle Pattern Interferometer system has been used for the Non-Destructive Testing of Composite laminates. This paper describes the application of this system to assess delamination and fiber breakage in Glass Fiber Reinforced Plastic (GFRP) laminates by analyzing the fringe patterns and by applying phase shifting techniques. GFRP laminates have been studied using the ESPI system in various optical configurations. This technique provides the full-field, non-contact method for NDE of composite specimens.
