  Composites Showcase! "Classic Recreations, a builder of high-performance custom vehicles, including Shelby GT500CR continuation cars, has announced its latest innovation — an authentic, officially licensed 1965 carbon fiber bodied CSX Shelby Cobra race car. As the most recent achievement to emerge from Classic Recreations, the full carbon fiber body follows the company’s 1967 carbon fiber bodied GT500CR Mustang which was released in early 2021. Only 10 of the new Shelby Cobra race cars, dubbed the “Diamond Edition” in honor of Shelby American’s 60th anniversary, will be produced. Granted CSX serial numbering, CSX4521 through CSX4530, by Shelby Licensing, each will feature a specially designed custom diamond-encrusted badge, featuring Carroll Shelby’s commemorative signature on the dashboard, and be sold as a completed race car." “What Classic Recreations has achieved with their carbon fiber program is the continuation of a dream Carroll Shelby himself envisioned for the fut

  Europe's sources of uranium supply: uranium demand increases by approximately 27% over the next 10 years. Still, nuclear capacities are being expanded in many countries. Do we still depend on uranium for nuclear reactors or be more focused on sustainability?

  Toyoda Gosei Co., Ltd. has developed* a cellulose nanofiber (CNF)-reinforced plastic with the aim of reducing CO2 over the lifecycle of automotive components, from raw material procurement and production to recycling and disposal. In moving toward decarbonization and a circular economy, Toyoda Gosei is developing materials that raise the environmental performance of its products by leveraging the following features of CNF. First, CNF has one-fifth the weight and five times the strength of steel. When used as a reinforcing material in plastic or rubber, the product can be made thinner and foam molding becomes easier. This reduces weight and contributes to lower CO2 emissions during vehicle driving. Second, when the material is reused after vehicles are scrapped, little strength is lost from heating and melting, making recycling automotive components possible. Third, it is a material that does not increase the total amount of CO2. Even when CNF is incinerated, the only CO2 emitted is t

  Microscopic Mondays! Kevlar broken samples from dynamic stabbing zoomed in! Research project "Dynamic/quasi-static stab-resistance and mechanical properties of soft body armor composites constructed from Kevlar fabrics and shear thickening fluids" published by Jianbin Qin, Guangcheng Zhang, Lisheng Zhou, Jiantong Li, and Xuetao Shi, investigated how different quantities of shear thickening fluid (STF) affect the knife-stabbing resistance and the quasi-static mechanical properties of kevlar composite samples. This collage shows photographs and SEM images of broken samples from the dynamic stabbing tests. (a), (d), (g) and (j) are the neat Kevlar fabric; (b), (e), (h) and (k) are the composite with 36.23 wt% STF; (c), (f), (i) and (l) are the composite with 103.79 wt% STF. The results show that the shear thickening fluid positively influenced the properties of the samples! Source: #managingcomposites

  Do we need to depend on Lithium-ion batteries for Electric vehicles for a decade or more? Climate changes have happened rapidly throughout many regions in the recent decade. On one side the deforestation takes place steadily in many regions and the natural resources are draining out a lot. Each country is losing its share of forest land every year drastically. On the other side, the sudden interest among Electric vehicle manufacturers made the world depend on lithium-ion batteries more than expected a decade ago. Some EV manufacturers are holding licenses for such minerals in the US for the lithium extraction for the Lithium Iron Phosphate battery cells. The world needs many materials for the production of an EV battery. Mining and deforestation happen at the same time everywhere that is not safe for the environment that we humans aim to create for future generations. Mining at depth will make the earth weakening as well as the water gets toxic too. Toxic rain will be the result. Don

  With Ultramid® A3U44G6 DC OR (PA66 - GF30 FR), BASF is expanding its portfolio of flame-retardant engineering plastics for the e-Mobility market. High technical requirements from the industry require innovative solutions based on PA66. In the case of already proven Ultradur® (PBT) products, color stability can be largely guaranteed, especially in orange (RAL 2003) which is in high demand in the industry. Conventional polyamides, however, tend to have strong color fluctuations or yellowing during heat aging. "High-voltage components are usually exposed to significant temperature fluctuations. This repeatedly leads to strong discoloration in conventional polyamides. Our newly developed type Ultramid® A3U44G6 DC OR closes the innovation gap in terms of color stability and mechanical strength", explains Tina Weller, Product Development BASF. For the first time, the new grade meets all the criteria of color stability and heat aging resistance and thus also enables long-lasting
