Lightweight: Equally carbon fiber and KEVLAR® fiber are light-weight elements, generating carbon KEVLAR® hybrid fabrics ideal for programs that demand large energy and stiffness when preserving bodyweight into a bare minimum.
Aramid fibres can be woven on fabric looms additional quickly than brittle fibres which include glass, Carbon or ceramic. In addition they exhibit inherent resistance to natural and organic solvents, Fuels, lubricants and publicity to flame.
Scientific American is part of Springer Character, which owns or has commercial relations with thousands of scientific publications (lots of them are available at ). Scientific American maintains a strict coverage of editorial independence in reporting developments in science to our audience.
