StructureSens: Development of a structurally integrated sensor system for fibre-reinforced plastics based on technical fibres with metal coatings and sensor wires
Project description
The aim of the project was the integration of component-specific sensor inserts (functionalised fibres and sensor wires) into continuous fibre-reinforced components for structural health monitoring and functionalisation. A sensor principle based on conductive metallic coatings for technical fibres was developed and implemented. The basis of the intended sensor system for structural health monitoring and functionalisation of fibre-plastic composites are the coated glass fibre rovings and sensor wires. The functionalised sensors make use of the inherent material properties, i.e. of the electrical conductivity of the sensor inserts. By measuring the electrical resistance, mechanical deformations can be detected and additional sensor functions integrated into the component.
The advantages over current structural health monitoring systems are:
- Structure- and process-integrated functionalisation
- Application for thermoplastic and thermoset matrix systems
- Structural health monitoring for damage detection
- Adaptive structures of the sensor insert for the application
