Combination of wood fibers and spider silk could rival plastic
Silk is a natural protein which is excreted by animals like silkworms and also found in spider web threads. The spider web silk used by Aalto researchers, however, is not actually taken from spider webs but is instead produced by the researchers using bacteria with synthetic DNA.
In the future, it will be possible to manufacture similar composites with slightly different building blocks and achieve a different set of characteristics for other applications. Currently, work is being carried out on making new composite materials as implants, impact resistance objects and other products.
