In this paper, the carbon-fiber-wrapped rotor strength for High-speed permanent magnet synchronous machine (HSPMSM) was studied. Firstly, considering the carbon fiber wrapping process, the carbon ...

Carbon-supported cobalt catalyst (Co-BP) and polypyrrole-modified carbon-supported cobalt catalyst (Co-PPY-BP) are prepared by an impregnation–chemical method and characterized by X-ray diffraction, X ...

While carbon fibre is prized for its lightweight properties, its production is notoriously energy-intensive. By swapping to a flax-based composite for a component like a car’s roof, BMW projects a ...

Carbon fiber-reinforced plastics (CFRPs) are widely used materials with outstanding mechanical properties. The wettability between the polymer matrix and carbon fiber in the interphase region ...

Reduced CO2 Emissions The use of natural fibers with reduced CO2 emissions and carbon footprint has become increasingly important. Tests have showcased that these composites have great suitability for ...

The BMW Group announced that it plans to expand the use of natural fiber composites, which have been used in lightweight racing cars, to future mass-produced models. After years of development and ...

In this paper, nanoscale anodic oxidation lithography using an atomic force microscope (AFM) is systematically studied on carbon nanotubes (CNTs). Trends between the produced feature size and the ...

The TA-20 has a maximum flight time of 8 h, a maximum range of 2,432 km and a maximum flight speed of 506 km/h. It can meet the needs of primary pilot training and is suitable for a variety of ...
