The demand for biobased polymers is growing fast. According to the current state of the art, metal-containing catalysts are needed to improve the polymerisation rate of lactones, posing a hazard to health and the environment. InnoREX will develop a novel reactor concept using alternative energies for the continuous, highly precise, metal-free polymerisation of PLA. In InnoREX, metal-containing catalysts will be replaced by organic catalysts. These have been shown to efficiently control the polymerisation of lactide, but their activity must still be improved to meet industrial standards. This will be achieved by the low-intensity but highly-targeted application of alternative energies (microwaves, ultrasound, laser light). These energies increase catalyst activity and enable precise control of the reaction by exciting only small parts of the reaction mixture without response time. To ensure short market entry times commercially well-established co-rotating twin screw extruders will be used as reaction vessels. The reason commercial polymerisations are not yet carried out in twin screw extruders is the short residence time and the static energy input of the extruder, which allows no dynamic control of the reaction. Again, these obstacles will be overcome in InnoREX. The project will utilise the rapid response time of microwaves, ultrasound and laser light to achieve a precisely-controlled and efficient continuous polymerisation of high molecular weight PLA in a twin screw extruder. Additionally, significant energy savings will be achieved by combining polymerisation, compounding and shaping in one production step. For a deepened scientific and engineering understanding of the reaction, the effect of the alternative energies on the reaction kinetics and the potential applications for alternative energies in reactive extrusion, offline chemical and polymer analytics and online characterisation and simulation of the process within the reactor will be carried out.

Poly(lactic acid) or polylactide (PLA), a biodegradable polyester produced from renewable resources, is used for various applications (biomedical, packaging, textile fibers and technical items). Due to its inherent properties, PLA has a key-position in the market of biopolymers, being one of the most promising candidates for further developments. Unfortunately, PLA suffers from some shortcomings, whereas for the different applications specific end-use properties are required. Therefore, the addition of reinforcing fibers, micro- and/or nanofillers, and selected additives within PLA matrix is considered as a powerful method for obtaining specific end-use characteristics and major improvements of properties. This review highlights recent developments, current results and trends in the field of composites based on PLA. It presents the main advances in PLA properties and reports selected results in relation to the preparation and characterization of the most representative PLA composites. To illustrate the possibility to design the properties of composites, a section is devoted to the production and characterization of innovative PLA-based products filled with thermally-treated calcium sulfate, a by-product from the lactic acid production process. Moreover, are emphasized the last tendencies strongly evidenced in the case of PLA, i.e., the high interest to diversify its uses by moving from biomedical and packaging (biodegradation properties, “disposables”) to technical applications (“durables”). © 2016 Elsevier B.V.

Inspection and Maintenance are important aspects when considering the availability of aircraft for revenue flights. Modern airframe design is exploiting new exciting developments in materials and structures to construct ever more efficient air vehicle able to enable smart maintenance including self-repair capabilities. The improvement in the aircraft safety by self-healing structures and protecting nanofillers is a revolutionary approach that should lead to the creation of novel generation of multifunctional aircraft materials with strongly desired properties and design flexibilities. In recent years, the development of new nanostructured materials has enabled an evolving shift from single purpose materials to multifunctional systems that can provide greater value than the base materials alone; these materials possess attributes beyond the basic strength and stiffness that typically drive the science and engineering of the material for structural systems. Structural materials can be designed to have integrated electrical, electromagnetic, flame resistance, regenerative ability and possibly other functionalities that work in synergy to provide advantages that reach beyond that of the sum of the individual capabilities. Materials of this kind have tremendous potential to impact future structural performance by reducing size, weight, cost, power consumption and complexity while improving efficiency, safety and versatility. Actually, also a very advanced design of an aircraft has to take required inspection intervals into account. An aircraft with inherent protective and smart abilities could help to significantly extend the inspection intervals, thereby increasing aircraft availability. The main objective of this EASN endorsed proposal is to develop and apply a multifunctional autonomically healing composite for aeronautic applications. The multifunctional composite systems will be developed with the aim of overcoming serious drawbacks of the composite materials.

On the 28th of September 2012, Six events will be organized in five Belgian cities in the frame of the European Researchers night : Brussels (2); Charleroi, Lige, Louvain-la-Neuve and Mons. For this edition, 17 partners agreed to animate the different events on the theme of Science@home : How science, research and innovation are indispensable in a normal house, and how they will improve our daily life and our houses in the (near) future... This theme will enable the citizens to better understand and appreciate the work of researchers but also the role of innovation to transform research results in concrete (daily) applications. Before the night, young people will be invited through a wide communication campaign, to draw the house of the future and to come afterwards to the nearest organized event if they were close from reality ! Animations, games, experiments, discussions, films, and other activities will make this event dynamic. The interaction between researchers and visitors will enhance the recognition of the role of the researchers in society and in daily life. It will also promote the careers of researchers among the younger public. Finally, this will help the public to go beyond certain preconceptions about researchers and show that these are not odd characters stuck in a laboratory, but people like you and me.
