Obiettivo del progetto (Objective)
'Bonded composite patches are ideal for aircraft structural repair as they offer enhanced specific properties, case-tailored performance and excellent corrosion resistance. Bonding further eliminates stress concentrations induced from mechanical fastening of metal sheets, seals the interface, and reduces the risk of fretting fatigue between the patch and the component. IAPETUS focuses on the use of improved composite repair systems offering (i) the introduction of new on-aircraft simplified curing technologies, (ii) enhanced fatigue and damage tolerance properties and (iii) integrated damage sensing. This will be performed via the incorporation of carbon nanotubes (CNTs) both in the composite matrix of the repair patch as well as in the adhesive. The use CNT modified repair concept will lead to improved performance in the blunting of stress concentrations in the parent surface and the inhibition of crack propagation, leading to enhanced fatigue resistance at the locus of the repair as well as for the patch itself. At the same time, the patch repair acquires additional functionalities. The CNT doped Carbon Composites can be tailored to reduce the galvanic corrosion in repaired Aluminium structures. As the patch becomes electrically and thermally conductive thermal energy can be infused in the patch either by direct resistance heating (using the patch itself as heating element via the application of electrical voltage) or by induction heating, to instigate a uniform matrix polymerization since the patch system appears improved thermal conductivity too. The electrically conductive percolated network can be employed to assess the damage within the patch and its interface with the repaired structure, as conductivity changes mirror the damage in the doubler/substrate system by tracing micro damage through breaches in the CNT network; thus, the structural efficiency monitoring at any stage in the service life of the aerostructure can be assessed non-destructively.'
Introduzione (Teaser)
When a defect occurs in an aircraft structure, the crack must be bonded. Novel composite patch repair technology exploits carbon nanomaterials for enhanced process control, patch performance and structural health monitoring.
