Fraunhofer IPT (Aachen, Germany) reported that it has developed a quasi-continuous fiber-based measurement system that assesses the temperature and rate of expansion in composite structures. The system comprises fiber probes up to 70m/230 ft long. In up to 7 million checkpoints, the probes record temperature variations of 0.1°C/0.18°F and expansions of 1 micrometer per meter. Fraunhofer says the small caliber of the fiber, combined with its flexibility, means it can be built relatively easily into components and semifinished products.
Editor PickA better method of structural health monitoring?
Fibersail, a 2014 startup firm with offices in Rotterdam, The Netherlands and Leça de Palmeira, Portugal, aims to change the current state of real-time structural health/shape monitoring for composite structures — initially, for wind farm operators.
