Rapid Processing of Net-Shape Thermoplastic Planar-Random Composite Preforms

Véronique Michaud, Patrick Blanchard, Martyn Douglas Wakeman, Simon Jespersen, Daniel Schmäh

A novel thermoplastic composite preforming and moulding process is investigated to target cost issues in textile composite processing associated with trim waste, and the limited mechanical properties of current bulk flow-moulding composites. The thermoplas ...

In situ strain and temperature monitoring of adaptive composite material

René Salathé, Véronique Michaud, Hans Georg Limberger

An optical fiber sensor is designed to simultaneously measure strain and temperature in an adaptive composite material. The sensor is formed by splicing two fiber Bragg gratings (FBGs) close to each other, which are written in optical fibers with different ...

Observation of pulse delaying and advancement in optical fibers using stimulated Brillouin scattering

Luc Thévenaz, Kwang-Yong Song

We demonstrate experimentally that it is possible to control optically the group velocity of an optical pulse as it travels along an optical fiber. To achieve this control we use the effect of Stimulated Brillouin Scattering. In our experiments we have ach ...
