New and Exotic Materials Thread

On the topic of potentially fantastic new materials, here is one that absorbs a lot of vibration - good for car seats and I'm thinking in stereo equipment although I haven't found anyone using it in that industry just yet.

Car seats for McLaren, body parts for Porsche, snowboards, surfboards, bicycle frames, boat hulls and so forth.

Flax is 9 percent lighter than carbon fiber and has five times the vibration absorption characteristics. Today’s F1 rules budget 176 lbs. (80 kg.) for the driver and seat, so any amount below that amount for the combination can use strategically placed as ballast elsewhere in the car. Meanwhile, the flax soaks up vibration 250 percent better than carbon, improving driver comfort and potentially aiding their focus on driving.

I'm kind of confused on the 5 X's verses 250% figures above, so maybe someone better at math and reading can sort it out for me.

Article I first found this product in, see below.

McLaren, Bcomp use natural composite fibers in F1 racing seat
The flax fibers meet strength and stiffness requirements while reducing vibration, cost, enhancing safety and lowering its CO2 footprint by 75%.

Quote:

German boatbuilder Greenboats, located in Bremen, have specialised in building boats from natural fibre composites. The Flax 27 is their latest stroke of genius – a daysailer with timeless design, made with ampliTex™ technical flax fabrics.

........................
Able to build on their experiences made with the GreenBente, Greenboats managed to largely build this unique daysailer from natural and recycled materials. The hull consists of flax fibres in the form of Bcomp’s ampliTex™ technical fabrics paired with a sandwich core consisting of recycled PET bottles. In a classic vacuum infusion process the fibers were infused with a plant-based epoxy resin in order to further reduce the CO2 footprint of the vessel. The deck is covered in naturally beautiful and grippy cork that presents a sustainable alternative to classic teak decking.

Natural fiber crash box design for motorsport

Quote:

According to Bcomp, the crash box is designed to optimize the performance of the ampliTex natural fiber reinforcements and was tested at the FIA-approved test house at the Polytechnic University of Milan. Producing results in line with a traditional carbon fiber structure, the material shows desired crash behavior required from a safety perspective and eradicates the danger of sharp splintering. Furthermore, natural fiber composites waste can be used for thermal energy recovery.

Flax, hemp and basalt all have a place in composite structures.

First thing that come to mind for me is duckduckgo.com/?q=separate+lithium+with+nanofiltration. Maybe I can add verbosity later.

Sometimes you read my mind.

Basalt Fiber = ASBESTOS ???

and if not, same difference. No one ever got sick breathing asbestos for the first few years.

Silicate needles vs continuous fibers.

Anything in a person's lungs other than air can be dangerous. The few nose hairs nature gave us just aren't set to filter much out.

Fiberglass Tied to Asbestos-Type Lung Disease

Quote:

A Japanese medical researcher has reported the first evidence that fiberglass, which is produced by the billions of pounds annually here and widely used as an insulating material, may be responsible for causing lung disease in workers similar to diseases caused by asbestos.

That's why Nature caused some humans to grow facial hair. They can curl their lip goatee up behind their mustache and make do.

I'd be more concerned by nanoscale cosmetics (titanium dioxide) than deconstruction of composite materials.

We have a sort of process to nullify particles in the lungs. It's the long particles that get stuck and irritate the cells that becomes the problem, long term. Carbon based particles generally degrade, not so much for non organics.

This relies on a nano-scaled structured surface on the material (Mylar), and frikkin' lasers.

Perhaps more interestingly, mice have been magnetically levitated for hours on end with no observed side effects! So the spaceship of the future will have the magnetically charge floor and ceiling [reversed], so it pushes the space-faring entity toward the floor.

Flax might not take so long to go mainstream, while hemp remains some sort of taboo nowadays. Basalt is also interesting, but it may get more demanded for more critical applications.

Taboo until it isn't.
