A composite aero-structure with self-repair capabilities will offer durability, extend its service life and prolong maintenance protocols leading to lower aircraft operational costs. Despite the extensive research activities in the area of self-healing resins applied to composite materials, the research for aeronautical applications is currently very limited. To this end, the main objective of HIP ...

Flexible Conductive Composite Repair Heaters (CONDUCTOR)

Date du début: 1 déc. 2011, Date de fin: 31 août 2014,

"Appropriate curing of the patch resin and the adhesive layer is an essential step to secure the integrity and the sound mechanical performance of a bonded composite repair. Today, the required elevation of temperature is usually achieved by means of resistance heating blankets, which conduct heat to the repair area, regulated through closed loop temperature control, using one or two spot temperat ...

"The wind turbine industry is the fastest growing market area for the use of composite materials. Current state-of-the-art turbines are increasing in size, providing multi-megawatt power output. To generate such power turbine rotorblade diameters exceeding 100m along with nacelle heights of 120m are becoming standard. As turbines grow and their deployment becomes more widespread and remote, it is ...

"The aim of MAGNASENSE is to develop the appropriate smart maintenance technologies, using magnetostrictive sensors, in order to enable self-sensing of the strain field developed in components manufactured by CFRP. For this reason, all the hardware (embedded sensors – sensing elements etc.) and software (transformation of measurements to strain readings, ispection supporting fotware, initial corre ...

"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 o ...

"Even though adhesively bonded composite repairs exhibit significant advantages in terms of mechanical efficiency compared to mechanically fastened ones, they are at the same time extremely sensitive to process parameters variations. Small deviations against the repair specifications (e.g. surface preparation) may lead to disproportionally larger consequences to the final mechanical performance of ...

"Composite materials are being used extensively in many industrial applications with higher production needs than the yielded by current technologies. New developments such as textile preforming combined with liquid moulding technologies will support this tendency. Nevertheless, there are still some drawbacks. More repeatable and automated processes are required and tools must be developed to assi ...

However they are at the same time extremely sensitive to process parameter variations. Small deviations against the repair specifications and subsequent flaws, could lead to disproportionally larger consequences to the final mechanical perform ...

"The required elevation of temperature for curing of composite repairs is usually achieved by resistance heating blankets, controlled through spot temperature measurements. Although this method is simple and works adequately for small repairs, when larger areas are heated, cold or hot spots frequently occur, due to variable heat losses, caused by geometrical asymmetry etc. For this reason, autocla ...

"The basic problem of damage detection is to deduce the existence of a defect in a structure from measurements taken at sensors distributed on the structure. Especially in aeronautical structures, cracks, delaminations and debondings are typical types of damages often encountered. The problem is essentially one of pattern recognition. Artificial neural networks show considerable promise for damage ...
