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

A review of polyethylene‐based carbon fiber manufacturing
Applied Research, 2022 AbstractCarbon fibers and their composites have attracted much attention in recent years and are being used in an increasing number of industries. However, due to the high production costs of carbon fibers and the complex manufacturing process of composites, their use in large series applications is still limited.
