The traditional carbon fiber production process uses polyacrylonitrile (PAN) and is very energy intensive. It is also slow. There is a big push for new production processes / material sources. Here's an example of technology using cheaper and less energy intensive acrylic instead: https://phys.org/news/2016-03-ornl-low-cost-carbon-fiber.html https://phys.org/news/2016-03-ornl-low-cost-carbon-fiber.htm... Or a plasma method making it from PAN but faster: https://www.youtube.com/watch?v=SLmU0BmLmFE https://www.youtube.com/watch?v=SLmU0BmLmFE So there is potential for large drops in price and increases in supply in the future. Probably the wind energy market is driving this.
