Re:Plant-based epoxy enables recyclable carbon fiber

Have you here contested claims that hemp - biocomposite with resin - has greater Tensile Strength and Compressive Strength than steel and aluminum (and carbon fiber with sustainable binder)?
If this were OT, we could reference ScholarlyArticles which describe experiments which return scalar intervals for: Tensile and Compressive Strength, Melting point / deployed heat resistance, production cost in real dollars, carbon cost (reduction in carbon tax credits because unnecessary with alternate sustainable inputs), resistance to corrosion due to sodium chloride, [in-space without water] repairability, magnetizability, water transport and filtration cost, and other factors; with a fair standard panel for relative comparison.
You want to know how you can quickly tell this is all bullshit?
Steel isn’t brittle. Not in any relative sense to composites. Saying something is weak and brittle… that’s dry spaghetti. Does steel failure remind you of that? Or does composite failure seem closer?
Carbon is brittle. Composites are brittle. Hemp with epoxy is going to be brittle,all relative to steel which has plenty of pliability to it.
Are you sure you know enough about composites to repeat these hemp claims? Because if “makes steel look weak and brittle” didn’t immediately flag for you, you either know a lot more than I’ve learned in 20 years of working around composites and manufacturing or you don’t and just want hemp to be cool.
Hemp might be amazing. But you are posting nonsense that it seems like you have some desire to believe for some reason.
Sure maybe it’ll get out of the lab just around the same time graphene does.
