From prototyping to flight hardware manufacturing and looking into the the future toward out-of earth manufacturing, this talk aim to expose the different aspect of polymer 3D printing (FFF/FDM) for space application. The European Space Agency is looking into the implementation and use of new materials to enable new applications for space. Polymers and polymer composites specially are part of such focus among others. However, the benefit of new functionalities or capabilities brought by materials shall be assessed against their behaviour under the effect of space environment. Effect of space environment (VUV, Thermal Cycling, ATOX) on the functional performance of advanced thermoplastics materials (PolyEtherEtherKetone-PEEK) focusing on electrically conductive PEEK processed by additive manufacturing will be presented. The results obtained on this material mechanical, optical and electrical performances be presented including demonstrator enable by such material and process combination. The effect of the process and its relation with the material on the final part performance will be discussed as well showing the importance of having a standardised approach to enable accurate part qualification. The recent advances on the use of 4D printing concepts suitable for space application will be exposed and discussed with an emphasis on the role of meso-structuration.

The monomeric ink is extruded from a print head onto a heated bed triggering the frontal polymerization (FP) reaction. Heat released from the polymerization activates adjacent monomer to further the curing process, thereby forming a self-sustaining propagating reaction wave that polymerizes the printed filament. The stiff polymerized segment of the filament can structurally support the printed part during its fabrication to produce three-dimensional (3D) free form printed structures with excellent fidelity. Fabricated parts exhibit a degree of cure of 99.2% and do not require further post-processing.  The addition of nanoparticles and other reinforcement phases allows access to a range of rheological profiles between low-viscosity liquid and free-standing elastomeric gel – all of which frontally polymerize upon thermal activation. This presentation will summarize the characterization of ink rheology for printing, influence of printing parameters, addition of reinforcing fillers, and the resulting mechanical properties of the printed structures.</span></li></ul></div> <div><br /><br /><a href="https://ui.ungpd.com/Surveys/e19f2bbb-3ee3-4e2f-b259-173b334d614a" style="outline:0px"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Register to the seminar </a><br /><br /></div> <div><a href="/en/areas-of-advance/materials/news/Pages/Additive-manufacturing-can-fundamentally-change-the-way-we-live.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Interview with Uta Klemenet: Additive manufacturing can fundamentally change the way we live</a><br /></div></span><span style="background-color:initial"></span><div><span style="background-color:initial"><br /></span></div> <div><h2 class="chalmersElement-H2" style="font-family:&quot;open sans&quot;, sans-serif"><span style="font-family:inherit;background-color:initial">About Materials for Tomorrow</span><br /></h2> <p style="margin-bottom:10px"><a href="/en/areas-of-advance/materials/news-and-events/Materials-for-Tomorrow/Pages/Materials-for-Tomorrow-2019.aspx">​</a>Materials for Tomorrow is an annual conference - started in 2010 - covering research, education and innovation in materials science.

For 1D nanomaterials their natural embodiment is as aligned fibres or fabrics that efficiently exploit the axial properties of their constituents. We work with a method to produce macroscopic solids made of 1D nanostructured directly collected as they grow floating in the gas phase. The resulting ensembles are “macromolecular” networks with many superior properties compared to monolithic materials: fibers of carbon nanotubes have tensile mechanical properties above many high-performance polymer fibers; fabrics of CNTs are ideal built-in porous current collectors to eliminate electron resistance limitations in composite battery electrodes, sheets of silicon nanowires are flexible and have high cyclability as lithium-ion battery anodes. </div> <div><br /></div> <div><b>Juan J.

Multifunctionality, for instance integrating energy storage capabilities to structural components, is a key enabling technology in realizing substantial weight savings on the system level. Carbon fibres are widely used as reinforcements in polymer composites, while graphite powders are widely used as negative electrodes in batteries. Thus, using carbon fibres as negative electrodes, together with solid electrolyte and other components, one can build the so-called structural composite batteries. Imaging the doors and hoods of an electric car also store energy! However, almost all carbon fibres were developed from the mechanical point of view; a fundamental understanding on the behaviour of carbon fibres under the dynamic electrochemical and mechanical processes in structural composite batteries, and on the relationship between their performance and microstructure are still largely lacking. We aim to gain a fundamental understanding of carbon fibres in the multifunctional composites.</div> <div><br /></div> <div><b>Fang Liu</b> is Associate Professor at the Department of Industrial and Materials Science.
