Lyutyy, Pavlo The properties of reinforced lightweight flat pressed wood plastic composites / Pavlo Lyutyy, Pavlo Bekhta, Galina Jevgenivna Ortynska, Ján Sedliačik. -- Obr., tab. -- Lit. - The properties of reinforced lightweight flat pressed wood plastic boards are examined in this study. The laboratory shredded low density polyethylene (rLDPE) particles, wood particles (WP) and expanded polystyrene (EPS) were used for making WPC boards. The fiberglass mesh and polypropylene fibers were used for reinforcing the lightweight WPC. The bending strength (MOR), modulus of elasticity (MOE), tensile strength perpendicular to the plane of the board (or internal bond-IB) and thickness swelling of reinforced lightweight WPC after immersions in water for 24 hours (TS) were evaluated. The results showed that the strength properties of WPC boards were improved with the addition of polypropylene fibers and fiberglass mesh. The fact that the values of MOR/MOE increased with adding the polypropylene fiber and fiberglass mesh by 11.6%/7.7% and 77.5%/51.3%, was found.The IB of lightweigthWPC reinforced with polypropylene fiber and fiberglass mesh increased up to 7.4% and 11.1% compared to unreinforced lightweight WPC. The TS was not affected by the addition of reinforcing materials. However, the obtained valuesof MOR, MOE, IB of the reinforced lightweight WPC meet the requirements of the standards EN 16368 and EN 312.
