Fun to know, Dyneema fiber has a tensile strenght versus weight several times over steel.
Long ago, i read this in a physics news magazine while still at school :
Kevlar is strong but this stuff is tough enough that even a knife with a diamond edge or diamoind saw can not cut this material.
Can you imagine that ? Tougher than diamonds ?
The only way to process it, is by use of a laser or heat.
The material has a very low melting point at around 150 degrees celcius.
At least that is what i read at the time.
Anybody know if that is actually true ?
Anyway what we all love, similar material like this stuff can possible be found in nature.
Like for example in the legs of crickets or the front paws of shrimps like the pistolshrimp AKA snapping shrimp, or the mantis shrimp. Maybe the stretchy material ?
Just an interesting thing to think about.
But i just read now in this day and age of sustainability , a biobased version has also been developed :
Bio-based Dyneema® fiber is the world’s first-ever bio-based HMPE fiber. Learn how it delivers the same high performance as Dyneema®, with a far lower carbon footprint.

General site :
A fiber that’s 15 times stronger than steel, yet light enough to float on water. Think it sounds too good to be true? Think again.
