Effect of furfurylation on physical and mechanical properties of Pinus elliottii wood

ABSTRACT Pinus wood presents undesirable characteristics that can be attenuated with the application of treatments, in which the furfurylation is highlighted. Therefore, the objective of this work was to evaluate the effect of impregnation of furfuryl alcohol on the physical and mechanical properties of Pinus elliottii wood. For this, 4 treatments were used: control and with different loads of furfuryl alcohol (10%, 25% and 50%). The properties were determined as described in ASTM D 2395-17 (2017) and ASTM D 143-94 (2014). It was verified that, for the mechanical properties, the compression resistance parallel to the fibers, in which the MOE parameter had a significant increase for all the treatments in relation to the control group, especially for treatment (TF25%), for the MOR, higher values were obtained, but without significant differences. Regarding Janka hardness, the maximum tension in the transverse anatomical plane, higher values were observed when compared to the control, with emphasis on treatment (TF50%), which showed higher values with significant difference. For the tangential plane, no significant differences were observed, maintaining the average values between the treatments and the control practically constant. For static flexion, MOR and MOE, no significant differences were observed, these properties being analyzed with ANOVA tests with significance of 5%. With this it can be concluded that the impregnation with furfuryl alcohol was effective, due to improvements in mechanical de-performance observed. Considering the potential of furfurylation employed in wood based on these results, it is suggested to do more research in this field in order to promote more information on the use of this wood treatment.
