Wood and other lignocellulosics have been used as “engineering materials” because they are economical, low in processing energy, renewable, and strong. In some schools of thought, however, lignocellulosics are not considered “materials” in that they do not have consistent, predictable, reproducible, continuous, and uniform properties. This is true for solid lignocellulosics such as wood, but not necessarily true for composites made from lignocellulosics. The chemistry of the components of lignocellulosics can be modified to produce a material with consistent, predictable, and uniform properties. Properties such as dimensional instability, biodegradability, flammability, and degradation due to ultraviolet light, acids, and bases can be altered to produce property-enhanced composites.
