Manufacturing Of Robust Natural Fiber Preforms Utilizing Bacterial Cellulose as Binder [PDF]

open access: yes, 2014
We present a novel method of manufacturing rigid and robust short natural fiber preforms using a papermaking process. Bacterial cellulose acts simultaneously as the binder for the loose fibers and provides rigidity to the fiber preforms.
