Abstract

In this study, kiri wood (Paulownia spp.) is assessed as potential core layer material for blockboards. Blockboards with core layers made of kiri and spruce (Picea abies) were produced using Anthocephalus cadamba as crossband veneer and beech (Fagus sylvatica) as face veneer. With spruce as core layer material, higher values for bending strength and modulus of elasticity, tested in grain direction, and screw withdrawal resistance were obtained. In return, blockboards with kiri as core layer material were 31% lighter and showed a more homogeneous core layer material with regard to density.
