Alright, I've been working in the materials industries for years, so I can see there is a lot of strange info here.
- First off carbon fiber is what you have after you burn everything else off. Yup that's how it's made, and it's not so environmentally friendly
- Second, carbon is the hardest substance known to man. mixing it in varied amounts with a strong yet flexible binder like epoxy allows a product to have the best of both worlds in varied amounts, as per design.
- Third, bamboo depends on it's cell structure for stiffness, and while it may be very stiff, it is not nearly as strong as carbon fiber by weight, and cannot be (carbon is as stiff as it gets)
- Fourth, once the bamboo is soaked in epoxy it is no longer environmentally friendly. It was up till that point but no longer
- Fifth, bamboo can rot, carbon can't. Which means that products made of bamboo have a life span, after which they will need a home int the dirt somewhere. Not necessarily so for carbon fiber
- Sixth, Carbon fiber used in a thermal set mold, using a blend of carbon, and nylon woven together instead of saturated with epoxy is one of the most durable products I have ever seen, and because it is a thermoplastic based binder, it could most likely be recycled.
There are many ways to use composites, of every type. In some cases not having to replace the product may be more environmentally sound than making it out of something semi-biodegradable like bamboo and epoxy. I'm just saying, that there are ups and downs to everything. It takes years and much useage to define the criteria, for environmentally sound, with any product. Wasn't to long ago I remember ethonal and biodesel were going to save the planet, and now we realize it's really not much better after all.
