    Eco-compass

    Composites are important materials used in aircrafts due to their excellent mechanical properties combined with relatively low weight enabling the reduction of fuel consumption. Expensive carbón fibre reinforced plastics (CFRP) are used in fuselaje and wing structures and increasingly replace classic metals. Glass fibre reinforced plastics (GFRP) are mainly used for the interior panels. All these composite materials used in aviation have one thing in common: they are man-made. Renewable materials like bio-fibres and bio-resins are under investigation for a long time for composites but they did not made it into modern aircraft yet. The Project ECO-COMPASS aims to bundle the knowledge of research in China and Europe to develop ecological improved composites for the use in aircraft secondary structures and interior. Therefore bio-based reinforcements, resins and sándwich cores will be developed and optimized for their application in aviation. relationship between both continents. The duration of the Project is three years.

    ResCiclo

    The objective of this project is the development of a methodology for assessing the residual strength of reinforced concrete structural elements that have been subjected to different dissipative events in their service life, both cyclic and monotonic ones. The evaluation of the residual strength of a structure or a structural part also gives an indication of its vulnerability at a given moment in its service life to posible future events. These may be of seismic origin, strong winds, vibrations, etc. Reinforced concrete will be analysed like a composition of materials with different constitutive laws for Steel and concrete. The overall behaviour at structural element level will be obtained by means of the generalized rule of mixtures that will also take into account the orientation of the Steel inside the concrete. The behaviour of each material component will be analysed with a fatigue numerical model that will be calibrated with experimental results found in literature. The main assumption of this study is that each material counts with an initial dissipation capacity that can be spent in one or several seismic events occurring in its service life. A structural element is considered to have failed when one or both of the constituents have exhausted their dissipative potential, or have stopped working together at a structural level due to loss of adherence. The predicted structural failure due to low-cycle fatigue and the remaining service life of structures during and after one or several earthquakes should be considered in the future in the design codes.

    OMMC

    Laminate composites have become the optimal material for the structural applications requiring of excellent stiffness-weight and strengthweight ratios. Among the different composite materials available, this project will focus in textile laminates. This project will develop a material design platform capable of providing a composite configuration that will optimize the composite mechanical performance and its structural adaptability. This will be achieved with the development of a multi-scale procedure,such as numerical homogenization, and multi-objective material design optimization code. The results obtained from this model are used afterwards to calculate the structure response to the actions applied. This project will also develop a new laminate macro-element that will incorporate the optimization procedure naturally. These elements will have to fulfill also other requirements specific of transportation structures such as handle large curvature gradients, changes in material orientation, variations of material through their thickness, etc. The code developed will lead to safer designs that will contain less material, with the consequent reduction in price, weight and energy requirements of the structure.
