The objective of this study was to assess the effects of heat released during forest fires on wood properties of Pinus taeda L. trees submitted to different burning levels (increasing fire intensity, I-IV). Wood samples were collected from trees in each of the burning levels and also from trees not affected by fire (control). Specimens were then extracted to evaluate the physical and mechanical wood properties; chemical composition was evaluated only for burning level IV and control. The analysis of the results showed that fire effects over the physical-mechanical properties and chemical composition in all burning levels did not cause sufficient chemical degradation and strength reduction, which could be cause for rejection of those woods for normal use. In the case of structural use caution should be adopted for the wood from burning levels III and IV, which had their mechanical property values reduced. |
