Description in original language: The particleboard (PB) industry faces a high demand for light, low-cost panels of specific mechanical properties. This may be hard to fulfil because the density and strength of wood are linearly correlated. Use of proper materials and composition, however, may result in panels of a high strength-to-weight-ratio. This allows saving raw wood and energy as the strengthened PB is useful for high-load-bearing application. A promising reinforcing material are basalt fibres. In this study, basalt fibres in the form of a scrim provided reinforcement inside the PB panel. The scrim used had an area weight of 360 g.mMINUS SIGN 2. Four compositions of 18 mm thick PBs and 640 kg.mMINUS SIGN 3 target density were produced using melamine-urea-formaldehyde (MUF) resin as the binder. Basalt scrims were positioned in the core, between the core and surface and in between both surface layers. The scrim used was either dry or additionally impregnated with MUF resin. The best variant proved to be the impregnated scrim placed in the middle of both surface layers. Its modulus of rupture (MOR) and modulus of elasticity (MOE) increased by 119 and 85% compared to the control panels, respectively. The setup also improved internal bond strength, screw withdrawal resistance and thickness swelling. Thus, basalt scrims at the outer positions significantly enhance the strength-to-weight-ratio of PBs.
