In this study, we have investigated the water absorption behavior of unsaturated
polyester /wood flour wastes composites materials. To achieve that, specimens were
prepared by using compressing method with different ratio of polymer matrix with org
anic
wastes produced from carpentry workshop (wood flour).Density of produced panels has
been measured and the obtained results showed that there is an ability to produce
hardindustrial wood panels. Practical experiments had been achieved to determine the
percentages of water absorption. Absorption test was achieved on the cut specimens by
immersing them in natural water (un-distilled) and measuring the gained weight of
specimens and the resulted swelling to determine the final changes in the product. Through
this study, we find that the absorbability has increased with the increment of organic filler
ratio and the practices sizes increment. In addition, we also find that the absorption
behavior follow Fickian law of diffusion in most specimens. We calculated the diffusion
coefficient D and other parameters of diffusion process and we also plotted the associated
plotsof the absorbability results. The obtained results showed that there is an ability to
produce planes of industrial wood without any pretreatment of wood flour.
