"In a win for chemistry, inventors at the Department of Energy's Oak Ridge National Laboratory have designed a closed-loop path for synthesizing an exceptionally tough carbon-fiber-reinforced polymer, or CFRP, and later recovering all of its starting materials. A lightweight, strong and tough composite material, CFRP is useful for reducing weight and increasing fuel efficiency of automobiles, airplanes and spacecraft. However, conventional CFRPs are difficult to recycle. Most have been single-use materials, so their carbon footprint is significant. By contrast, ORNL's closed-loop technology, which is published in Cell Reports Physical Science, accelerates addressing that grand challenge." #polymers #recycling

📣 Hot off the press: new research publication!  PhD researcher Rens Pierik’s most recent research paper is now available: “𝑨 𝒔𝒕𝒂𝒕𝒆-𝒓𝒂𝒕𝒆 𝒎𝒐𝒅𝒆𝒍 𝒇𝒐𝒓 𝒕𝒉𝒆 𝒕𝒓𝒂𝒏𝒔𝒊𝒆𝒏𝒕 𝒘𝒂𝒍𝒍 𝒔𝒍𝒊𝒑 𝒆𝒇𝒇𝒆𝒄𝒕𝒔 𝒊𝒏 𝒑𝒍𝒚-𝒑𝒍𝒚 𝒇𝒓𝒊𝒄𝒕𝒊𝒐𝒏 𝒐𝒇 𝑼𝑫 𝑪/𝑷𝑨𝑬𝑲 𝒕𝒂𝒑𝒆𝒔 𝒊𝒏 𝒎𝒆𝒍𝒕”. The article discusses the development of a transient model to describe the ply-ply friction response during hot press forming of continuous fiber-reinforced thermoplastics. Implementation of this advanced friction model will improve predictions on defect generation, enabling first-time-right defectless manufacturing. The research was performed as part of project PERFECT, together with Sebastiaan Wijskamp and Wouter Grouve and in close cooperation with the Production Technology research group of Remko Akkerman from University of Twente. A special word of thanks to NWO (Dutch Research Council) for funding the project. Learn more about the study: 👉 https://lnkd.in/eEQ-Q-5i #publications #manufacturing #research #composites

https://lnkd.in/dNCPXDZb Excited to share our latest published research! Multifunctionality through Embedding Patterned Nanostructures in High-Performance Composites. A programmable spray coating is introduced for the deposition of multiple nanomaterials with tailorable patterns in composite. It is shown that such patterns regulate the formation of interfaces, damage containment, and electrical-thermal conductivity of the composites, which is absent in conventional manufacturing that primarily rely on incorporating nanomaterials to achieve specific functionalities. Molecular dynamics simulations show that increasing the hydrophilicity of the hybrid nanomaterials, which is synchronous with shifting patterns from disk to ring, improves the interactions between the carbon surfaces and epoxy at the interfaces, manifested in enhanced interlaminar and flexural performance.

📣 In collaboration with national and international partners, researchers at the Institute of Materials Engineering have published novel results on an additively manufactured high-temperature shape memory alloy in the Journal 📰 of Virtual and Physical Prototyping. Titanium-tantalum (Ti-Ta) high-temperature shape memory alloys (HT-SMAs) are promising candidate materials for actuator applications at elevated temperatures. Researchers of the Institute of Materials Engineering, in collaboration with partners from TANIOBIS GmbH in Germany and RMIT Centre for Additive Manufacturing in Australia, have conducted a novel study on these smart materials. The authors report on the microstructure and functional properties of an additively manufactured Ti-30Ta (at.%) alloy. For the first time, Ti-Ta HT-SMA bulk structures were successfully processed using electron beam-based powder bed fusion (PBF-EB/M) technique. PBF-EB/M processed structures with near full density and an isotropic microstructure were obtained. Following an adequate post-process heat treatment, a reversible martensitic phase transformation well above 100°C was found. The article is titled "Electron beam powder bed fusion of Ti-30Ta high-temperature shape memory alloy: microstructure and phase transformation behaviour".
