Descripción del proyecto
Nuevos métodos para probar la calidad de las uniones adhesivas en aviones de materiales compuestos
Los materiales compuestos constituyen el 50 % de las estructuras primarias de los nuevos modelos de aviones. La creciente demanda de estos materiales está apremiando a la industria aeroespacial para que desarrolle técnicas de inspección rentables y fiables para los ensamblajes híbridos unidos mediante adhesivos, en particular para uniones débiles y defectos estructurales difíciles de detectar. El proyecto financiado con fondos europeos SealedwithoUTaKiss combinará métodos de evaluación no destructivos, técnicas de inspección de procesos en la línea de producción y pruebas mecánicas para determinar el rendimiento de los ensamblajes unidos de forma adhesiva. Al combinar conocimientos especializados de distintos campos, el proyecto dará a la industria aeroespacial europea una ventaja competitiva, lo cual redundará en unas aeronaves más fiables, con bajo consumo de combustible y de bajo coste.
Objetivo
With the growing demand of composites in aircrafts (more than 50% composites are used in new models), growth in air transport fleets across the world (increasing at 5.65% CAGR), rise in market of MRO operations (increasing at 4.4% CAGR by 2020) and structural failure being the second most common cause of aircraft incidents (16.5% of incidents), it is evident that the aerospace industry needs a reliable, cost-efficient inspection solution for composites and adhesively bonded hybrid assemblies, specifically for kissing bonds and other hard to find structural defects.
SealedwithoUTaKiss presents NDT inspection techniques including a TRL6 demonstrator of laser shock and ultrasonic guided waves for the reliable detection of structural defects in bonded assemblies (e.g. kissing bonds) with a high level of accuracy. The project will implement mechanical adherence testing and comparative experimental analysis of different NDT techniques, as well as identifying different defects in various hybrid bonded assemblies. Our solution will allow the highly reliable, widespread implementation of adhesively bonded assemblies in the aerospace industry by using a combination of NDT methods, inline process inspection and mechanical testing during the manufacturing process.
To realise the stated objectives, SealedwithoUTaKiss brings together strong expertise in the areas of composites, adhesively bonded hybrid materials, kissing bond creation and aircraft component manufacturing from GMI; laser shock, inline inspection and defect detection algorithm development from BUL; and NDT techniques, ultrasonic guided waves, mechanical testing and adhesives in bonding from TWI.
SealedwithoUTaKiss will give the European aeronautical industry a technological and competitive advantage in the growing need for use of adhesively bonded assemblies in aircraft resulting in lightweight aircraft, enhanced performance, better fuel efficiency, lower cost and environmentally efficient flight operations.
