Vliv povrchového materiálu na ohybové vlastnosti dřevotřískových desek s redukovanou hustotou

Abstract

The research was partially inspired by sandwich constructions, where the core delivering lightweight attribute and covering material the strength. In the research particleboards covered by different overlays were produced. The bending strength, modulus of elasticity, tensile strength and swelling properties were determined. Properties were compared with particleboard without overlay as well as between each tested group using Analysis of variance (ANOVA) and descriptive statistics. The HPL shown the most promising results while veneered surface delivered further questions considering swelling
