  An Automatic Drawing Machine for Producing Paper Metamaterials Metamaterials are described as synthetically created composite materials whose structured microstructures, rather than the materials’ chemical components, determine their properties. In other words, they are engineered materials with properties that aren’t found in nature. Researchers from Nanjing University has capitalized on those properties by designing an  hat uses pens and pencils to transfer metamaterials onto paper. A new paper from that team describes their novel technique, which uses a ballpoint pen with conductive ink to draw conductors and mechanical pencils to draw resistors and resistive films. These were incorporated into a computer-controlled drawing machine that makes the deposition process more automatic with increased accuracy. “Although paper-based metamaterials have been made previously using inkjet printing technology, our drawing technique is lower cost, simpler and more flexible,” explains ...

  Simonelli undertakes research to reuse composite materials Simonelli Group is currently undertaking a research and development project to reuse composite materials, that nowadays have a vast range of uses and applications thanks to their durability and longevity, but which are also very difficult to dispose of. The De-Manufacturing research project, developed by Delta srl and Simonelli Group, is part of the Marche Region’s Marche Applied Research Laboratory for Innovative Composites (MARLIC) platform in the context of ‘Sustainable manufacturing: eco-sustainability of products and processes for new materials and de-manufacturing’. “We are truly delighted to take an active part in this virtuous synergy, promoted and developed also within the MARLIC platform as advocates of a dual objective, to make a strong contribution to the transition towards a circular economy and to grow and develop the local industrial system,” says Fabio Ceccarani, Simonelli Group Managing Director. “The De-...

  Surprising complexity in simple particle model of composite materials Researchers from Tokyo Metropolitan University have used computer simulations to model how a composite material reacts to loading. They studied a particle model of a pillar of stiffer material in a soft matrix, finding a concentration of force around the pillar with a broadness that differed from theory. The team found this was due to subtle changes in density near the pillar, a new principle to be considered in composite material design. When you build a house of cards, it's not enough to have cards with the right weight or stiffness: the trick is how you put them together to make a stable structure. The same thing can be said about  composite materials . When scientists think about materials made of lots of different components, the properties of the final product are not just a linear sum of its parts, but strongly dependent on its complex internal structure. Composites encompass a vast range of materia...

  Faurecia advances biocomposites, recyclability, reduced CO2 and sustainability in automotive Faurecia is advancing sustainability within its four business groups: Seating, Interiors, Clean Mobility and Electronics. Across these divisions, the company aims to reduce the CO 2  footprint of the materials it uses by 87% by 2030, developing them based on three pillars: use less, incorporate recyclable and recycled materials and create alternatives to petrol solutions, with no impact on cost.  the company created a new cross-functional division, Sustainable Materials, to further develop and manufacture cutting-edge sustainable and smart materials and fulfill these sustainability objectives. Leveraging ultra-low, negative CO 2  emission materials, as well as materials integrating thermal, acoustic and biomedical technologies found under the Interiors and Seating Groups portfolios, the Sustainable Materials division seeks to wor...

For instance, the Boeing 787 contains around 50% composite materials. The risk of delamination, or the separation of those many layers, which might be brought on by operating circumstances and impact hazards, is the difficulty in employing composites. According to Davidson, the idea has uses in both the military and the commercial sectors. Davidson says, “ The military wants to more finely tune the service life of these composites. They want to know ...

  Optimizing the Manufacturing Process of Composite Materials Widespread in aerospace, laminated fiber-reinforced polymer matrix composites are also increasingly used in other sectors, including the automotive industry. The identification of optimal cutting parameters for a given tool composite pair is of utmost importance, as this can significantly reduce component non-conformance. During final aircraft assembly, surface delamination during machining results in 60% of part rejections. A significant experimental effort is required for understanding and controlling delamination, which typically manifests in systematic drilling and the subsequent analysis of a thousand holes. The Intellegens deep learning software,  Alchemite™ , can reduce this experimental time by quantifying complicated nonlinear tool-composite relationships. Alchemite ™  guides tooling design and selection before an experimental campaign by facilitating the analysis of complex data relationships. From sp...

This can be particularly apparent in machining, where FRP part-specific defects occur. A common cause for prescribing overly-conservative cutting tool use limits is process uncertainties that result in a large, unpredictable defect generation based on part quality criteria. An application-specific approach is required to identify the most effective cutting strategies due to the wide array of available tool designs and workpiece material configurations. Using an exhaustive, ...

A special coating that they developed, using a type of two-dimensional material called MXene, has shown to be capable of absorbing and disbursing the electromagnetic fields that are the source of the problem. While researchers and technologists have progressively reduced this problem with each generation of devices, their strategy thus far has been to encase vital components with a shi...

  IMDEA Materials Institute introduces novel recyclable sandwich structure composites Researcher Dr. Xuebao Lin. Photo Credit: IMDEA Materials Institute The Madrid Institute of Advanced Studies in Materials Science   ( IMDEA   Materials Institute, Madrid, Spain) is playing its part in the European Union’s transition to a   c ir cular economy with new   work in recyclable, flame-retardant materials. Its research is said to be producing advances in environmentally friendly sandwich-structured composites, widely used in the aerospace, automobile, shipping and rail industries. Such materials have traditionally been manufactured in a Nomex honeycomb form. However, as researcher Dr. Xuebao Lin explains, such material structures are almost impossible to recycle or reuse. “Traditional sandwich composites are composed of different materials joined with a strong adhesive and it’s very difficult to separate them,” Dr. Lin says. “They cannot be recycled.
