摘要：
Fiberboard sheet materials containing cellulosic fibers ae disclosed in which cellulose nanofibrils are used as a binder for adhering the cellulosic fibers together. The cellulose nanofibrils are present in an amount of 0.5% to 7.5% by weight on a dry weight basis of the fiberboard sheet. The fiberboard sheet materials have strength properties that meet or exceed the requirements in ASTM C208, and are useful for structural sheathing and roofing board applications. A process for manufacturing the fiberboard sheet is also disclosed.
