Power thrust for spider silk

(PhysOrg.com) -- Spiderman would definitely have an easier time of things with this spider silk - for example, if he had to stop a getaway car moving off at 100 kilometres per hour. A five-millimetre-thick thread would do the job from a distance of 20 metres - assuming it had been treated by a team of researchers from the Max Planck Institute of Microstructure Physics. The same task would require a finger-thick thread of untreated spider silk and a steel rod as thick as a forearm. The Max Planck scientists strengthen the natural material by infiltrating it with metal ions. It may also be possible to strengthen other natural and synthetic fibres in this way.
