Biodegradable Fibers As Strong As Steel Made From Wood Cellulose
Zothecula writes "A team of researchers working at Stockholm's KTH Royal Institute of Technology claim to have developed a way to make cellulose fibers stronger than steel on a strength-to-weight basis. In what is touted as a world first, the team from the institute's Wallenberg Wood Science Center claim that the new fiber could be used as a biodegradable replacement for many filament materials made today from imperishable substances such as fiberglass, plastic, and metal. And all this from a substance that requires only water, wood cellulose, and common table salt to create it. The full academic paper is available from Nature Communications."
Stronger than steel is cool and all, but that doesn't necessarily mean "all the same properties of steel". Durability, heat tolerance, reaction to moisture and a host of other things are likely to mean it's not a drop-in replacement for fibreglass/plastic/metal.
Fibreglass is terrible at all of the things you just listed and we use it for all kinds of things. It just has to be coated with a thin protective layer.
Carbon fibers are five times stronger than steel and about a third the weight, so in a head to head competition, no way.
Still, it could compete with (say) steel if it's easier to work, cheaper, and less polluting.
