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.
