In this work, we analyzed the influence of the addition of fibers on the properties of particle board. In laboratory conditions, we have produced a single-layer and three-layer board from industrial particles, to which we added 0 %, 17 % and 41 % of the fibers. We have found that most of the characteristics of particle board improved by adding fibers. The density of particle boards increases with the addition of fiber, this results in better mechanical properties and modulus of elasticity. The best bending strength and modulus of elasticity had panel D, which contained 41 % of the fibers in the surface layer and 17 % of the fibers in the core layer. The lowest thickness swelling was determined at panel with no fibers while the highest at panelC with a fiber content of 17 % in the core layer. The smallest change in weight by immersion in water was found in panel D and the highest in panel A.
