Recently, the 16-meter first-stage fuel-tank forming mold for WELIGHT-1, WELIGHT’s medium-lift liquid reusable launch vehicle, successfully rolled off the production line. This milestone marks a key breakthrough for WELIGHT in the design and manufacturing of high-precision forming tooling for large composite tanks, laying a solid foundation for the efficient, high-precision, and scalable manufacturing of all-carbon-fiber tanks. Faced with the challenge of having few mature solutions to reference in the manufacturing of large composite tanks, the WELIGHT team moved beyond conventional metallic mold design and pioneered a honeycomb sandwich structure without internal supports. While meeting both lightweight and high-stiffness requirements, the design limits the mold's self-deflection to within 1.0 mm when supported at both ends, with all key performance indicators meeting the design requirements. From having no mature path to follow to developing an innovative solution capable of mee...

Avantium N.V., a leader in renewable and #circularpolymermaterials , today announced the completion of the spin-out of its #ParanaTechnology into Parana Materials B.V. Parana Materials is a new, independent company focused on the development and commercialization of #plantbasedhighperformancepolyesters such as PISA, PISOX and PEIT/PEIF. The Parana Technology portfolio is distinct from Avantium's #FDCA and #PEF (branded as #releaf® ) technology, which remains fully within #Avantium . The transaction is part of Avantium's strategy to focus resources and investments on its core FDCA and PEF business while enabling other promising technologies in its portfolio to pursue independent growth and commercialization pathways. Parana Technology enables the production, application and #recycling of renewable, high-performance polyesters through simpler and more cost-effective synthesis routes using commercially available monomers such as #isosorbide , #succinic - and #oxalicacid , and...

The agreement aims to strengthen the connection between industry and research, promoting advanced research activities and experimental development focused on the design of new smart materials capable of meeting the market needs increasingly driven by lightweight design, high performance and technological innovation. The partnership brings together two complementary areas of expertise. IPCB-CNR contributes the scientific excellence and multidisciplinary capabilities of its 73 researchers and 11 technologists, while Xenia brings more than 30 years of industrial experience in reinforced composite materials, combined with a strong innovation-driven approach and a forward-looking vision focused on the technologies and applications of tomorrow. At the core of the agreement is the development of materials engineered for injection moulding, a key technology for industrial production, but also for the most advanced manufacturing platforms, including pellet- and filament-based 3D printing.  ...

One could think that amorphous polymers (often more viscous, so with a longer relaxation time) should produce as much, if not more, orientation effects. But, at least as far as shrinkage anisotropy is concerned, they typically don't. In a semi-crystalline matrix the much faster freezing induced by the phase change and the intricately mixed morphology of the resulting two-phase system (amorphous and crystalline regions), leads to an overall much higher locked-in orientation of the amorphous regions, easily visualized by annealing induced post-shrinkage. Of course the crystalline phase will also have its own anisotropy, for instance in terms of preferred crystalline orientation, possibly obse...

In Europe and Western world, we pat ourselves on the back for banning single-use plastics. Enjoy sipping our drinks through paper straws and feel like sustainability heroes. Meanwhile, in Asia, 40% of food never even makes it to the table. Let that sink in. While we debate biodegradable forks, food rots in the sun because there’s no plastic film to preserve them. No cold chain. No airtight seal. No protection from heat, pests, or time. 𝗧𝗵𝗲 𝗧𝗿𝗲𝗮𝘁𝘆 𝗖𝗼𝗻𝘂𝗻𝗱𝗿𝘂𝗺 🚫 𝗧𝗵𝗲 𝗪𝗲𝘀𝘁 𝗯𝗮𝗻𝘀 𝗽𝗹𝗮𝘀𝘁𝗶𝗰. 🍚 T𝗵𝗲 𝗘𝗮𝘀𝘁 𝗹𝗼𝘀𝗲𝘀 𝗳𝗼𝗼𝗱.

The materials are venting: ➡ #PET (water bottles): “I was designed to be recycled, yet people keep tossing me in general waste. Imagine training for the Olympics and never being allowed to compete.” ➡ #PE (shopping bags, sachets): “I get blamed for everything—from clogged drains to microplastics. But blaming me without fixing waste systems is like blaming the umbrella for getting wet when you never opened it.” ➡ #PLA (plant-based plastic): “Every time someone hears ‘biodegradable,’ they expect me to disappear in their backyard. Sorry folks, I need the right industrial composting conditions—not your garden soil.” ✅ #Therapist (an aluminum can, infinitely recyclable): “Maybe the issue isn’t who you are, but how humans manage you. Misuse, misunderstanding, and misinformation cause more damage than the material itself.” #Keytak...

That fizzy soda or chilled juice you enjoy on a hot day isn’t just about flavor — the can holding it is a quiet marvel of metallurgy. 🔷 The Challenge 🔸 Be lightweight (for easy transport). 🔸 Be strong enough to hold pressurized gas (carbonation). 🔸 Stay non-reactive with acidic drinks (cola, citrus, juices). 🔸 Be cheap to produce in billions every year. 🔷 The Metallurgical Solution: Aluminum Alloy 🔸 Most cans are made of aluminum alloy (AA3004/3104). 🔸 Aluminum provides lightness (a can weighs ~15 grams) and strength (when work-hardened during forming). 🔸 Inside, cans are coated with a thin polymer lining so the drink doesn’t corrode the metal. 🔷 Why Not Steel? 🔸 Steel is stronger, but far heavier. 🔸 Shipping costs would soar if billions of cans were steel. 🔸 Aluminum recycles far more efficiently — saving energy and costs. 🔷 Fu...
