Toray and Gordon Murray unveil carbon-fiber T-Wave AR1 Concept EV Sports Car

Green Car Congress

27 city EV, earlier post ) to create the T-Wave AR1, a concept EV two-seater to demonstrate the extreme weight savings possible with Toray’s carbon fiber composites. The use of carbon fiber for the frame as well as more typical parts, such as exterior body panels and seats, keeps the weight down to 846 kg (1,865 lbs).

NREL develops novel method to produce renewable acrylonitrile; carbon fibers from renewable biomass

Green Car Congress

Today, acrylonitrile is used in the production of acrylic fibers for carpets, clothes, and fabrics, and in plastics such as food containers, and packaging materials. The high acrylonitrile yield allows us to propose a potential industrial process for the conversion of lignocellulosic biomass to renewable acrylonitrile and carbon fibers.

BASF investigating sodium-air batteries as alternative to Li-air; patent application filed with USPTO

Green Car Congress

However, this system can also suffer from similar high overpotentials and low energy efficiencies when using carbonate-based sodium electrolytes. The cell consisted of a metallic sodium anode, a glass fiber separator and a carbon-fiber gas diffusion layer (GDL) as the cathode. 1 (carbon), corresponding to roughly 3.3

Ford LCA harmonization study clarifies benefits of lightweighting for vehicle life cycle energy use and GHG emissions

Green Car Congress

To facilitate a direct comparison of results from the various studies we adjusted the LCA results in two steps. CFRP = carbon-fiber reinforced plastic, GFRP = glass-fiber reinforced plastic, HSS = high-strength steel, c = fuel-mass coefficient). Credit: ACS; Kim and Wallington. Click to enlarge.
