Today's KNOWLEDGE Share 📢Time to Get Technical📢 Back to fundamentals. 👀 One of the most important variables in composite design is not just the material itself, but how the reinforcement is arranged within the laminate. Short fibers, chopped strand mats, woven fabrics and unidirectional reinforcements can all be made from the same fiber, yet deliver very different mechanical properties. Why? Because fiber orientation directly influences how loads are transferred through the structure. The more aligned the fibers are with the applied load, the more efficiently the material can carry it. This is why reinforcement architecture is such a critical design parameter in composite engineering. Same constituent materials. Completely different structural behavior. 🕵🏻‍♀️ What trends do you notice in the graph? 🤔 source : The Native Lab

TotalEnergies Corbion today announced the commercial launch of #Luminy®FOAM50F , a high melt strength #PLA grade designed for extrusion foamed packaging applications. Developed for trays used in fresh food products, like meat and fish, and food service packaging such as clamshells and bowls, the material delivers the performance of conventional #extrudedpolystyrene (XPS) while providing a lower-carbon, circular alternative. As packaging producers face increasing regulatory pressure to phase out polystyrene in food applications and with restrictions expanding globally, the market is actively seeking alternatives that combine environmental benefits with industrial scalability. Luminy® FOAM 50F addresses this need with a bio-based, industrially compostable material that enables a practical transition without disrupting established production processes. Luminy® FOAM 50F is engineered as a drop-in replacement for PS, allowing converters to run it on existing XPS extrusion lines with compa...

Norda® and Envalior continue to push the boundaries of trail running performance with the launch of the 055, the latest evolution of high-performance footwear powered by Envalior’s Arnitel® thermoplastic copolyester elastomer (TPC) midsole technology. Building on the success of the norda® 005, the new 055 is engineered specifically for ultra long-distance racing and highly technical terrain, combining enhanced cushioning and rebound with the lightweight durability and stability required by elite trail runners. Demonstrating its performance in competition, ultra runner Rachel Entrekin recently won the Cocodona 250 race in Arizona in a record time, while wearing the 055 throughout the full 250 miles. The 055 highlights the versatility and resilience of Arnitel® foam technology across multiple trail running applications. While the norda® 005 was designed as the lightest and fastest trail racing shoe, the 055 expands the performance platform with a thicker Arnitel® midsole for greater cush...

Fibre handling and composites technology specialist #CygnetTexkimp has developed a VHD (very heavy duty) creel solution capable of handling 500kg packages of fibre as part of an industry collaboration to increase efficiency in carbon fibre manufacturing. The large-scale creel will be used to unwind bobbins of #PANprecursor fibre into #carbonfibre production lines. Its development signals a major leap in capability for the carbon fibre manufacturing industry which has, for over a decade, relied on fibre packages weighing up to 350kg. The impact of the new technology will be to reduce operational downtime and increase efficiency by cutting the frequency of package changeovers and allowing longer continuous run cycles between package changes. Cygnet Texkimp is a market leader in the manufacture and supply of #VHDcreels to the carbon fibre industry with over 70 VHD creels in operation globally, processing in excess of 24,000 bobbins of fibre. Peter Stevenson, Director of Projects at Cy...

Brazilian manufacturer of structural composite panels Diprofiber – which also supplies raw materials for composite processing – has launched #CoreFloor , the country’s first #thermoplasticcompositeflooring system intended for industrialised construction, i.e. the manufacture of all or part of a building’s components in an industrial setting, followed by their assembly on site. CoreFloor uses a #glassfibre reinforced thermoplastic composite sheet as its surface layer. The #Diprofiber system combines high mechanical strength with low weight; it is recyclable and can be installed quickly – a requirement that is becoming increasingly common in construction projects, given ever-shorter deadlines and tighter control over project delivery. Data centres are an example of an application where the installation process is particularly quick, making ready-to-install modules very useful. In this context, composite panels offer advantages in applications traditionally dominated by steel, aluminiu...
