Natural Fiber Composite Mats

Just came across them in the latest Composites issue ( and wondering if anyone has played around with them yet. At 300 g/m^2 , they’d be a bit of a weight sacrifice but I can’t imagine how much easier they would be to work with as the meat to the sandwhich. No more trouble bending around tight corners! The article claims they are “cheap” but didn’t list a price.
