However, natural regeneration of trees cannot satisfy the growing demand for this raw material in some parts of the world. Wood is a valuable material that can be used in a variety of applications.

A combination of 10% camel-thorn and 5% wollastonite fibers produced panels with the best properties. Up to 10 % camel-thorn could be added to panels without negative effects. Wollastonite fibers significantly improved most of the physical and mechanical properties while addition of camel-thorn produced more variable effects on panel properties. Approximately 30 % of the wollastonite fibers were less than 100 nm while the remainder were less than 1 μm. The effects of wollastonite fibers on the physical and mechanical properties of medium-density fiberboards composed of wood fibers with up to 10 % camel-thorn chips were studied.
