Like carbon fiber, but from flax!
Porsche is making parts for its new 718 Cayman GT4 Clubsport that look like carbon fiber, but it is flax, requires 75% less energy to produce than CF, can be ground down and reused (instead of burned at very high temperatures to disposed of), and "has five times better vibration dampening properties than carbon fiber, so it doesn't splinter when hit hard."
The new doors, made from flax, weigh 13% more than the old ones, made from carbon fiber, and it is not as strong, so they can only use it on the race car, not the street variant. Eventually they hope to make non-structural components. It is also more expensive--for now! https://www.popularmechanics.com/car...gt4-clubsport/

Yeah, but CF is used for strength, which the flax doesn't have. Also, when my super expensive Porsche finally becomes worthless (not likely), I don't really care if the doors can be ground down and made into something else. Ease of destroying the doors doesn't sound like a feature to me.

Industrial hemp (free of THC) it's cheaper than flax (more costly than carbon fiber holly s...), and probably stronger, and also have fine absorption of vibrations.
But the fact it's a relative of the drug plant version make it a problem.

Weaker... More costly...
Now it just need a funny name to became a fully joke, like these :

Flax should have properties similar to hemp.
Vibration damping is also a property basalt fiber.
Quote:
Also used in Rossignol’s snowboard laminate, basalt is stronger and lighter in weight than fiberglass with more elasticity than carbon. Basalt enhances board feel, power and stability while absorbing impacts and vibrations.

Basalt also bend instead of shattering.

It's the same plant. Just a different part of the plant grown grown under different conditions.

Hemp composite doors could hold very well while hammered heavily with a huge hammer, due vibration dampening ability. Not huge impressive hardness strenght itself... But I imagined it was somehow stronger than flax, but not as good as carbon fiber.
I imagine it can compare to carbon fiber only in special circunstances, like a door do not get broke, like flat areas bend and absorbs impact, but not compare to structural strenght of cabon fiber to chassis.
There is already a lab hemp 100% free of THC, that I supose need no special growning conditions to avoid the THC. This should be enough to avoid legal problems and avoid drug dealer and drug users.
The ecologic propertis of hemp, like low water required, fast growning, strong resistance to insects, make it a powerfull plant. Just the drug needed to be genetically removed.

Horticulturalists don't need genetics to control the expression of the genetic potential of the two species (Indica and Sativa). But you know, control freaks gonna freak.
One could turn away from the Book of Leviticus and mix fibers. Short basalt fibers for bulk with loonng hemp fibers for reinforcement, with a percentage of glass for fiber-optics. Embedded cables for signalling and a gossamer web that is illuminated and scanned for breaks making [whatever object] a smart material.
Or Flax, of course....

Microfiber towels Okay then?
I just mentioned that for the contrast with smart materials.
