Factors affecting the embedding of optical fibre sensors in advanced composite structures.

05 - 07 Oct 1992.
Composite materials offer tremendous benefits for engineering applications and arc now specified for use in several safety critical studies. However, despite extensive materials research and development, they do have a number of areas where their behaviour is still not fully understood. This is particularly so with the more complex mechanical parameters in larger structures. Current structural design attempts to allow for these unknowns by overdesigning, extensive testing and frequent inspection.
Embedded optical fibre sensors offer the potential to monitor many of these parameters, and are additionally of a similar physical and mechanical nature to the reinforcement fibre used in advanced composites.
