Are there any natural fibres that are stronger than carbon fibre?

It depends what you mean by stronger. usually no, however they are doing have some fascinating characteristics and advantage over carbon fiber for a few applications. Flax (linen) offers similar performance to an optical fiber (the most cost-effective and fewer smart grade), flax is around 2/3rds as robust in tension as carbon fiber. Flax is superior to carbon inflexibility. Note the word ‘around’ as it’s a natural material, therefore, can vary from one selection or batch to the subsequent, this limits its technical use as engineers wish to figure to consistent levels of performance, however, for fewer difficult applications it’s an amazing material with very nice aesthetic qualities (unidirectional flax artifact sounds like hardwood, heat, and welcoming therefore nice for a few novel applications like trendy seating, musical instruments, even hulls).

cf cfFor someone inquisitive about learning composites I might start up with a reasonable linen artifact to find out the fundamentals, it’ll prevent little fortune, once you’re comfy with a linen composite example then use the dearer carbon fiber. Silk has some fascinating properties, its terribly abrasive resistant as an example (so smart for applications like canoes). Its nearest equivalent is Kevlar, however, neither are nearly as good in durability compared with carbon fiber. A science laboratory has experimented with feeding silkworms carbon nanoparticles (I don’t assume it harms them, however it apparently improves the modulus).

Nanotubes can higher align on the silk because it is discharged and drawn. Carbon nanotubes supply the potential for improvement over carbon fiber and might be added to the organic compound system additionally, however, neither of those is natural merchandise. The advantage of natural merchandise is usually, they’re cheaper, bio-degradable and supply smart abrasive resistance and with good adhesion with the organic compound system (which can even be a bio-resin) and adaptability. Natural fibers are way more versatile, smart for things like rope and (sail)cloth. Flax usually grows in most places (unlike short stable cotton), most countries made it once upon a time because it has long staple length fibers, it had been well-known to be spun from a minimum of 3,000 BCE and cultivated since the bronze age.
