Plastic Made From Fruit Rivals Kevlar In Strength
jldailey618 writes "A group of scientists from Sao Paulo State University developed a way to use the nanocellulose fibers from bananas, pineapples, and other fruits to create incredibly strong, lightweight plastics. The plastic is up to four times stronger and 30 percent lighter than petroleum-based plastics, and it rivals Kevlar — the material used in bullet proof vests — in strength."
The last time someone tried to compete with DuPont with a cheap and available material, they lobbied congress to ban the material, which they did.
I for one do not wish to have bananas, pineapples, or any other fruit be classified as a schedule I controlled substance.
Is strong really the correct term to use here? People think of kevlar being strong because it's used to stop bullets, but they're really completely wrong. Sure, it's stronger than steel, but not as strong as fiberglass or carbon fiber. You use kevlar in armor because it is tough, toughness being defined by the area under the stress/strain curve. It can absorb more energy than any other material. If it's as strong as kevlar, well then there are plenty of other natural and synthetic fibers that are just as capable, and this is nothing impressive. If it's as tough as kevlar, well then there is something of significant interest here.
