Wood Pulp Extract Stronger Than Carbon Fiber Or Kevlar

Zothecula writes "The Forest Products Laboratory of the US Forest Service has opened a US$1.7 million pilot plant for the production of cellulose nanocrystals (CNC) from wood by-products materials such as wood chips and sawdust. Prepared properly, CNCs are stronger and stiffer than Kevlar or carbon fibers, so that putting CNC into composite materials results in high strength, low weight products. In addition, the cost of CNCs is less than ten percent of the cost of Kevlar fiber or carbon fiber. These qualities have attracted the interest of the military for use in lightweight armor and ballistic glass (CNCs are transparent), as well as companies in the automotive, aerospace, electronics, consumer products, and medical industries."

Women might be impressed with bulletproof wood, but transparent?

With transparent they'd be surprised.

Uh, at least in the US and Canada the trees used for making pulp come from forests owned by the paper companies and they sure as hell replant them when they harvest. Mead Westvaco (as an example) has a fairly long term view of things, they own 3M acres and process them in a fashion that minimizes the amount of land they have to purchase to meet demand. The only bad thing about timber harvesting is that there's no old growth forests, but those were cut down generations ago and have little to nothing to do with modern forestry practices.
