Today's KNOWLEDGE Share Full carbon fiber composite fairing delivered for first flight of Tianbing Technology’s Tianlong 3  The large-diameter full carbon fiber composite fairing of Tianbing Technology’s Tianlong 3 (TL-3) launch vehicle rolled off the production line. “Tianbing Technology has fully mastered the development capabilities of large-scale composite cabin sections and achieves another major breakthrough in the development of high-quality, high-efficiency, low-cost products. The rocket fairing is located at the front end of the rocket and is an extremely important and complex section of the rocket. The TL-3 large fairing has a diameter of 4200 mm and a length of about 13 meters. It is made entirely of carbon fiber composite materials. It is the largest fairing in domestic commercial aerospace and the largest full carbon fiber fairing in China. It is also the first domestic fairing that is customized for satellite internet constellations. It can be called the most advanced

Avient Corporation, a provider of specialized and sustainable materials solutions and services, announces a successful collaboration with its long-standing and valued customer, Hager Group. Avient supported Hager to incorporate 27% recycled ocean-bound plastic into its new cubyko leaf waterproof outdoor sockets and switches, providing its customers with a more eco-conscious option. This success was achieved in further collaboration with Plastic Bank. It provides the recycled ocean-bound plastic waste that Avient formulates into high-performance polyolefin materials. Replaces Primary Materials by Meeting Technical Specifications Avient constributed to this success by developing customized versions of its Maxxam™ REC Recycled Polyolefin Formulations. It contains 50% recycled ocean-bound plastic content, using Social Plastic® feedstock from Plastic Bank. As a result, the final assembly of the Hager cubyko leaf includes 27% ocean-bound plastic content. These formulations effectively replac

A new composite material is finding its way into the construction industry. Made from natural stone, carbon fibers and biochar, it is an alternative to reinforced concrete. It is characterized by a particularly good CO2 balance. The DITF is leading the joint project “DACCUS-Pre*”. The basic idea of the project is to develop a new building material that stores carbon in the long term and removes more CO2 from the atmosphere than is emitted during its production.        In collaboration with the company TechnoCarbon Technologies, the project is now well advanced – a first demonstrator in the form of a house wall element has been realized. It consists of three materials: Natural stone, carbon fibers and biochar. Each component contributes in a different way to the negative CO2 balance of the material: Two slabs of natural stone form the exposed walls of the wall element. The mechanical processing of the material, i.e. sawing in stone cutting machines, produces significant quantities of st

Today's KNOWLEDGE Share Injection Molding creates non-monotonic crystallinity gradients through the thickness, and corresponding non monotonic elastic modulus. On one hand the rapid quench of the skin (combined with fountain flow) reduces crystallinity of the most outer layers leading to typically half the nominal modulus ( PP data). The high shear just below (frozen skin) will produce strong "flow induced nucleation" and more crystallinity ( and oriented structures). These layers can be 4X stiffer than the skin in PP. Finally the core section undergoes a more quiescent crystallization with slower cooling and shear rates and will have "average" crystallinity, larger non-oriented crystals and pretty much the data-sheet kind of modulus . source:Vito leo

 CJ Biomaterials, Inc, continues to expand the applications for its advanced PHA technology, announcing that their biopolymers are being used by California-based Beyond Plastic to develop the world’s first completely biodegradable plastic bottle cap. CJ Biomaterials is a division of South Korea-based  CJ CheilJedang  and a primary producer of  polyhydroxyalkanoates (PHA)  biopolymers. Both Recyclable and Compostable: “ We are proud to be working with Beyond Plastic to help make this innovative solution a reality. These PHA-based bottle caps not only address the pressing environmental concerns associated with traditional plastic caps, but also demonstrate the versatility and effectiveness of our PHA technology in delivering sustainable alternatives, ” says Max Senechal, chief commercial officer at CJ Biomaterials. “ We remain committed to advancing eco-friendly solutions that contribute to a healthier, more sustainable planet. ” Derived from nature and produced sustainably, CJ Biomateri

Milliken & Company will bring its full range of additive and colorant solutions for polypropylene (PP) and polyethylene (PE) plastics to NPE 2024. Milliken joins industry leaders for the expo to explore novel and sustainable pathways for plastics, enabled in part by the company’s comprehensive polymer additive portfolio. Opportunity to Collaborate with Plastics Value Chain: Milliken works across the value chain to enable PP and PE formulations that make plastics more reusable, recyclable, and efficient without sacrificing performance. With a range of clarifier and nucleator agents, masterbatches, polymeric colorants, and viscosity and performance modifiers, Milliken’s portfolio helps its customers and brand owners achieve their own sustainability goals. “We look forward to NPE, as it’s an exciting opportunity to collaborate with the entire plastics value chain under one roof,” shares Milliken’s global vice president for Plastic Additives Wim Van de Velde. “Milliken offers a suite o
