It is also slow.&lt;p&gt;There is a big push for new production processes &amp;#x2F; material sources.&lt;p&gt;Here&amp;#x27;s an example of technology using cheaper and less energy intensive acrylic instead:
&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;phys.org&amp;#x2F;news&amp;#x2F;2016-03-ornl-low-cost-carbon-fiber.html&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;phys.org&amp;#x2F;news&amp;#x2F;2016-03-ornl-low-cost-carbon-fiber.htm...&lt;/a&gt;
Or a plasma method making it from PAN but faster:
&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=SLmU0BmLmFE&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=SLmU0BmLmFE&lt;/a&gt;&lt;p&gt;So there is potential for large drops in price and increases in supply in the future. 
Probably the wind energy market is driving this.</text><parent_chain><item><author>nullsandwich</author><text>Currently, Boeing can not replace the 737 with a Carbon Fiber plane because there isn&amp;#x27;t enough Carbon Fiber produced on earth to keep up with the production line completing three aircraft a day.
