Stiffness and strength of oil palm wood core sandwich panel under center point bending

摘要: Abstract This paper presents a study of the bending's stiffness and strength oil palm wood (OPW) core sandwich panel overlaid with rubberwood veneer under center point bending. Parameters including density grain orientation OPW core, thickness span length were investigated. An experimental evaluation some mechanical properties bending beams was performed. Linear elastic beam theory used to predict performance panels. Results show that linear uses power law expressions Young's moduli shear as function derived within this study, adequately predicted beams. Higher increased beam. Failures by face fracture observed which latter tended occur at low density, relatively thick short length. Grain little influenced board. Finally, failure load equations board proposed for practical product.
