Properties of Sugar Cane Bagasse to Use in OSB

The composites of natural fibers are products known in several parts of the world, however their utilization is relatively restrict due to the lack of information concerning their properties and structures. Lignocellulosic fibers present high length/thickness relation, which contributes to the biodegradation and continuity of the ecological cycle. Such fibers present low density and enable a lower cost in composites manufacture, playing an important role in the definition of their physical and mechanical properties. The cane bagasse is a residue derived from sugar cane, a commercially important product in Brazil, with a high concentration of fibers, high content of lignin, which is a factor of environmental impact, with future perspectives of use. The present paper aims to evaluate the density of cane bagasse as composites of long particles and their internal adhesion, as well as to verify their temperature until decomposition and suggest their possible future utilization. The requisites of this product in terms of limit values for the properties of OSB are defined by EN-300/2002 standard.
