Abstract
A method of making a natural fiber composite panel includes extracting bamboo fibers from bamboo and embedding the extracted bamboo fibers in a polymer matrix material. The bamboo includes bamboo fibers and lignin, and the step of extracting includes mechanically scraping the bamboo fibers to remove at least some of the lignin. In some cases, the bamboo is steamed, soaked in water, soaked in an acidic solution and/or soaked in an alkaline solution before mechanical scraping.
