Descripción del proyecto
Volar alto gracias a una nueva técnica futurista de fabricación de compuestos
Las posibilidades de la fabricación aditiva (FA) para la producción de partes necesarias en la aviación civil podrían un día llegar a ser infinitas. Actualmente, sin embargo, las técnicas de FA de termoplásticos padecen de un rendimiento mecánico mediocre, lo cual las vuelve inadecuadas para fabricar partes con la fiabilidad necesaria. El proyecto Print2fly, financiado con fondos europeos, desarrollará una técnica futurista de fabricación de compuestos que produzca partes reciclables, complejas, robustas y durables para la industria aeronáutica. En concreto, está introduciendo un nuevo método de FA basado en la extrusión denominado «Reactive Liquid Deposition Modelling» (RLDM) para fabricar compuestos termoplásticos reforzados con fibra continua que presentan altas prestaciones y son fiables a temperatura ambiente. El proyecto está conceptualizando una nueva formación interfase entre la capa depositada recientemente y las capas solidificadas. También está relacionando las microestructuras o nanoestructuras con el rendimiento de unión y la macromecánica de los compuestos.
Objetivo
Within the field of aircraft manufacturing and aerospace sector, there is an increasing emphasis on thermoplastic composites and Additive Manufacturing (AM). However, current thermoplastic AM techniques are not suitable to manufacture parts with required reliability. These products suffer from poor mechanical performance stemming from the inherent weakness of printable polymers, high void content and weak bonding between printed layers. Current thermoplastic AM techniques are thermally-driven processes with serious limitations in processing of engineering thermoplastics due to high melt viscosity and process temperature of such polymers. Therefore, Print2fly is devoted to developing a new extrusion-based AM method named Reactive Liquid Deposition Modelling (RLDM) to fabricate reliable and high-performance continues fibre reinforced thermoplastic composites at room temperature. The RLDM technology employs photopolymerization of a liquid resin with tailored flow-ability and polymerization kinetics instead of the conventional melt processing. Print2fly conceptualizes a novel interphase formation between the freshly deposited layer and solidified layers and bridges the nano/micro-structure to the bonding performance and composite macro-mechanics. Print2fly will be a futuristic composite manufacturing technique to produce durable, robust, complex and recyclable parts for the aircraft industry.
The chance to perform this multi-disciplinary project within a world leading thermoplastic composites laboratory will give me the opportunity to excel my competencies in polymer chemistry, mechanics of composites and advanced characterizations. This will extend my scientific knowledge in thermoplastics and AM and augment my professional maturity and independence, helping me to grow my professional network. The fellowship will open excellent career possibilities for me to reach a group leader position in the materials science and production technology fields as a future prospect.
