Particle mats of three-layer construction were preheated by radio-frequency heating under pressure, then pressed into boards in a hot-platen press. The pressing mechanism in both stages and the properties of the boards were studied for various combinations of preheating and pressing times. Preheating dries the core rapidly and affects the density distribution and strength properties.
