Objectives

Scientific objectives

• To design and manufacture novel layer concept with multifunctionality based on nanomaterials, combining next properties:
  • Electrical / thermal conductivity capable of distribute the necessary heat on composite surface to prevent ice formation on its surface in rough fly conditions or remove the already existing one. With respect to current electrothermal system it can be estimated that a weight reduction of 99% and a power consumption reduction of 50% can be achieved.
  • Fire resistance. Reduced flammability (50% of reduction in Heat Release Rate HRR with respect to base composite material).
  • Sensing of temperature and stress by electrical conductivity variation measures.
• Integration, modelling and validation of multifunctional system in novel structural composite materials.

Scientific objectives

• Coupling of the conductivity characteristics of the composite with ice /fire protection and health monitoring systems.
• Development of modelling tools which will facilitate analysis and design of multifunctional layers.
• Manufacturing and validation of composite components with ice/ fire protection, as well as sensing capabilities for real time temperature and damage assessment.

Final objective of the LAYSA proposal is to develop a multifunctional layer with thermal and electrical conductivity, improved fire performances and sensing capabilities to be incorporated in aircraft composite structures for ice and fire protection, as well as health monitoring.
