In this paper, we present an improved FBG sensor system using a wavelength swept fiber laser(WSFL) for internal strain monitoring of composite laminates. The WSFL provides unique and functional output characteristics useful for sensor interrogation. In addition a realtime signal processing program was made to measure strains. Five FBG sensors in an optical fiber were used to measure internal st...

Abstract. Matrix accumulations, buckling and tearing of fibers metal sheets are common defects in the deep drawing fiber laminates. The previously developed in-situ hybridization process is a single-step method for manufacturing three-dimensional laminates (FML). During FML, low-viscosity thermoplastic matrix injected into dry glass fabric layer using resin transfer molding process. concurrent ...

This paper investigates the scattering characteristics of the fundamental anti-symmetric (A(0)) Lamb wave at through holes in composite laminates. Three-dimensional (3D) finite element (FE) simulations and experimental measurements are used to study the physical phenomenon. Unidirectional, bidirectional, and quasi-isotropic composite laminates are considered in the study. The influence of diffe...

This study aims to examine the phenomena that occur due projectile penetration on fiber metal laminate. Ballistic testing was carried out experimentally according National Institute of Justice standards (NIJ Standard 0101.06 level III-A) using a 9 mm full-metal jacket with normal angle attack (90° target). The results showed laminate could withstand rate by penetrating first layer (aluminum pla...
