Monitoring strain gradients in adhesive composite joints by embedded fiber Bragg grating sensors

Véronique Michaud, Hans Georg Limberger, John Botsis, Georgios Violakis, Roohollah Sarfaraz Khabbaz, Luis Pablo Canal Casado

The adhesive bonding of composite materials can be applied to assemble light-weight structures for aeronautical applications. However, the application of adhesive bonds in primary load-bearing structures is limited by the lack of adequate techniques to mon ...

Dynamic bending compensation while focusing through a multimode fiber

David Ziegler, Demetri Psaltis, Christophe Moser, Salma Farahi

Multimode fiber endoscopes have recently been shown to provide sub-micrometer resolution, however, imaging through a multimode fiber is highly sensitive to bending. Here we describe the implementation of a coherent beacon source placed at the distal tip of ...

Studies of mode I delamination in monotonic and fatigue loading using FBG wavelength multiplexing and numerical analysis

John Botsis, Joël Cugnoni, Samuel Stutz

Bridging by intact fibers in composite materials is one of the most important toughening mechanisms. However, a direct experimental assessment of its contribution is not easy to achieve. In this work a semi-experimental method is proposed to quantify its c ...
