  📢The Composites Bandwagon!📢 Today we would like to showcase one of our first customers and longest partnership! A global group that covers a wide spectrum of activities; from the development and assembly of electric powertrains, battery packs, and fast loading infrastructure programs, to the development of high-performance electric vehicles: @QEV Technologies! Fun fact: Our relationship with them started when @Lluc Marti Fibla (our CEO) accepted the role of Composites Manager and Hispano Suiza Project Manager at QEV! So, back to QEV! The company offers a unique and masterful engineering service in this sector and uses a model focused on the development of custom electric cars, carrying out all the aspects involved in the process. With many years of experience in motor racing, which includes its successful participation in the FIA Formula-E World Championship, QEV has the incredible ability to design, build and offer all the necessary technical support for new electric prototype...

  📢Spreading the Word!📢 Pressurized steam-based composites recycling for full fiber reclamation! "To date, the most common methods of recycling composite components and materials are pyrolysis (flame-based) or thermolysis (heat-based), solvolysis (chemical-based), hydrolysis (water-based), or some type of mechanical process (chopping or shredding whole parts for reuse, etc.). The end product for most of these processes is a fiber with reduced mechanical properties (the resin having been burned or chemically melted off), suitable for chopping up for potential reuse as a filler, in a nonwoven, mat, or perhaps in injection molding or spray-up applications." "@Longworth is one company promising a new method for reclaiming both near-virgin-grade fibers and resins. Called DEECOM, the process uses high-temperature steam and pressure to separate and reclaim materials. After a decade of development and proving out the technology, the company is ready to launch DEECOM commercial...

  📢It's time for our segment Endless Possibilities!📢 Hublot roars in the year of the tiger with the unique spirit of the big bang gold tiger watch! As the lunar year begins, Hublot introduces a version of its barrel-shaped icon in Frosted Carbon and gold, a first for the Swiss fine watchmaker. The watch, which is based on the barrel-shaped 42mm Spirit of Big Bang, is a striking execution of Hublot’s famous fusion principles. This is the first Spirit of Big Bang with a case made of Frosted Carbon and 18-carat yellow-gold, a black and gold fusion of materials Hublot has used in its collection only once before. This unique, complex, beautiful material, developed by Hublot, fuses carbon fiber with gold to create a unique finish defined by its glimmering gold occlusions. The watch is limited to 200 pieces and no two will be exactly the same. The patterns created by the process are random, just like a tiger’s majestic stripes. Interested? Better start saving some money, because th...

  📢Microscopic Mondays!📢 Have a look at this knotted aramid fiber! What is going on? The anisotropic behavior of aramid fiber can be revealed in a vivid manner through SEM micrographs like this one: Note the buckling or kink marks on the compressive side... Meanwhile, the tensile side is smooth! Such markings on the aramid fiber surface have also been reported when the aramid fiber is subjected to uniform compression or torsion! Do you know why this happens? Let us know in the comments!  Bibliographical Reference: Composite Materials - Science and Engeneering - Page 50 Source: #managingcomposites Visit MY BLOG http://polymerguru.blogspot.com

  Healing Halogens  #medicine A significant number of drugs are halogenated. Typically, insertion of halogen atoms on hit or lead compounds is performed to occupy the binding site of molecular targets in order to improve the drug−target binding affinity and/or reduce metabolism. 14 out of the 50 molecules approved by the FDA in 2021 contain halogens. The introduction of F onto a chemical scaffold is able to infer changes that affect the physicochemical properties and the conformation of a molecule. Being the most electronegative element in the periodic table, F plays an important role in the modulation of pKa of neighboring functionalities. Substituting F for H on aromatic groups is also well known to improve metabolic stability. Lipophilicity is also affected by the addition of F onto aliphatic and aromatic scaffolds. The monofluorination or trifluoromethylation of saturated alkyl groups usually decreases the lipophilicity due to the strong electron-withdrawing capabilities o...

  📢Spreading the Word!📢 Leonardo, Vertical Aerospace to jointly develop VX4 eVTOL carbon fiber fuselage! "Vertical Aerospace an aerospace and technology company pioneering zero-emissions aviation has agreed to a joint development program with Leonardo for the design, testing, manufacture, and supply of the carbon fiber composite fuselage for Vertical’s VX4 electric aircraft." "The VX4 is a near-silent, entirely electric, piloted aircraft that is expected to have a range of more than 100 miles and to reach top speeds of up to 200 miles per hour. With a four-passenger capacity, Vertical says the zero-operating emissions VX4 will also have a low cost-per-passenger mile, similar to that of a taxi." "Vertical and Leonardo will work together on optimizing lightweight composite structures, modular design, systems installation, and structural testing for the co-development of the aircraft’s fuselage. According to Vertical, this is currently in place for at least six ...

Evonik is further expanding its portfolio of 3D-printable biomaterials for medical technology: The specialty chemicals company has developed VESTAKEEP® iC4800 3DF, a new osteoconductive PEEK filament that improves fusion between bone and implants. The high-performance polymer can be processed in common extrusion-based 3D printing technologies such as fused filament fabrication (FFF). Evonik will present the new product for the first time at the AAOS trade show in Chicago, USA (March 22-26, 2022). Excellent Biocompatibility and Biostability The new PEEK filament is a biomaterial from Evonik's VESTAKEEP® Fusion product line launched in 2020. The high-performance polymer impresses with excellent biocompatibility and biostability as well as improved osteoconductive properties. The osteoconductivity was achieved by using a functional special additive - biphasic calcium phosphate (BCP). The BCP additive allows bone cells to adhere to implants more quickly, thus positively influencing the...
