James Cropper Advanced Materials and Hexcel are working together through the Aerospace & Defence working group of the European Composites Circular Alliance (ECCA) to advance the development of high value composite materials made from recycled carbon fibre that support both performance and circularity across aerospace, automotive and mobility sectors. The collaboration between #JamesCropper and #Hexcel centres on the use of UNIMAT, enabled by James Cropper’s VECTIS aligned fibre technology, as a practical model for how recycled #carbonfibre materials can achieve the alignment and fibre volume fractions needed to compete in demanding composite applications. The objective is not alignment alone, but the development of enhanced, high-value recovery #composite materials made from recycled carbon fibre that deliver meaningful structural performance. Within ECCA, a core focus is the advancement of composite materials derived from recycled fibre for aerospace and defence applications, ...

  MoU in between Owens Corning and Tree Composites : Today at JEC World we signed a Memorandum of Understanding with Owens Corning, marking an important step in scaling composite joint technology. By combining Owens Corning’s global expertise in glass reinforcement with #TreeComposites joint technology and industrialisation approach, we will work on further optimising glass solutions for large-scale #composite joints. For us, strengthening the material ecosystem around compositestep toward large-scale deployment of this technology. Good to meet the #OwensCorning team in person and looking forward to the next phase of collaboration. source : Maxim Segeren #JECWorld #composites

Today's KNOWLEDGE Share 📍 Plastic Mold Polishing: The Key to Enhancing Product Quality and Manufacturing Efficiency 💡 In the injection molding industry, the process of plastic mold polishing is not just a finishing step; it is a critical factor that determines the final product's quality, durability, and aesthetics. 👉 Why is mold polishing essential? 1️⃣ Improved Aesthetics & Surface Finish: - Goal: Achieve optimal Surface Roughness for the Cavity and Core. - Benefit: Molded products boast a high-gloss finish, minimizing surface defects and ensuring a premium, professional appearance. 2️⃣ Optimized Mold Release: - Goal: A super-smooth surface reduces friction. - Benefit: Products are easily ejected from the mold, reducing Cycle Time, preventing mold damage, and lowering the scrap rate. 3️⃣ Enhanced Mold Durability: - Goal: increases the hardness of the mold surface - Benefit: extending the mold's lifespan—crucial for high-volume production runs. 4️⃣ Maintaining consi...

For high-temperature applications in contact with food, BASF is now offering a portfolio of polyphenlysulfone (PPSU) grades which is not based on Bisphenol S (BPS) and Bisphenol A (BPA). This Ultrason® P portfolio thus complies with EU Commission Regulation 2024/3190 which prohibits Bisphenol in food contact materials and articles. After defined transition periods, these articles are no longer allowed to be produced in or imported into the European Union. The six Ultrason® P grades, their data sheets, necessary material certificates and food contact approvals are available as of now: Manufacturers of e.g., reusable bottles, catering tableware, coffee machine components or high-heat pans can timely start to re-qualify their food-contact applications currently made of e.g., polyethersulfone (PESU) which will also be impacted by the ban. BASF thus supports a smooth transition toward compliant articles while offering a broad PPSU portfolio that enables food-contact parts with...

Today's KNOWLEDGE Share What is the glass transition in plastics, really not from a datasheet point of view, but from the polymer molecule and up? Plastics soften, become rubbery or flow when used above their glass transition temperature (Tg). Below Tg, those same materials become stiff, brittle and glassy. Parts crack in cold environments. Impact resistance disappears. What worked fine yesterday suddenly fails today. The glass transition is the temperature range where molecular mobility becomes mechanically relevant. It is not a chemical change or a melting event. - The polymer does not melt. - No chemical bonds are broken. - The chemistry does not change. - There is no phase change. Tg arises from cooperative segmental motion: small segments of polymer chains start to move together, enabled by sufficient thermal energy and free volume. Below Tg, polymer chains are effectively locked in place, like a tangled ball of yarn. Stress is stored elastically, leading to brittle fracture. ...

High-end bicycle manufacturers are entering a new era where frames and components must be lighter, stiffer, tougher, and more sustainable, all while enabling fast, repeatable, and cost-efficient production. To meet these demands, Teijin Carbon is expanding its portfolio of advanced prepreg systems, specifically tailored for premium road, gravel, and mountain bike applications. Drawing from its aerospace heritage, Teijin Carbon utilizes resin systems, fiber grades, and layup technologies originally engineered for certified aircraft structures. This expertise has resulted in a sports-focused prepreg range designed to help bicycle brands achieve new levels of performance, structural reliability, and design freedom. "Lightweight alone is no longer enough in high-end cycling. Brands now look for a balanced combination of stiffness, toughness, durability, flexural performance, and sustainability," said Yuki Tamenaga, vice president Global Sports Marketing & Strategy at Teijin C...
