Mechanical Properties of 9-layer Laminated Pine Wood Veneers Reinforced with Various Materials

Abstract

The bending strength and compressive strength properties of wooden laminated elements reinforced with various materials were investigated in this study. Veneers with 9 layers were prepared from Scots pine (Pinus sylvestris L.) wood, which is used extensively in Turkey. The veneers were glued with PVAc-D3 adhesive by placing support elements (PVC plastic mesh, fiberglass/PVC mesh, and aluminum wire mesh) between them. The density, bending strength perpendicular to the glueline and bending strength parallel to the glueline were determined in the specimens prepared in conformance with the TS 5497 EN 408 (1998) standards. All of the support materials increased the bending resistances of the specimens. The highest bending strength and compressive strength was obtained in the specimens reinforced with aluminum wire mesh, whereas, the lowest bending strength was obtained in the control specimens and the lowest compressive strength was obtained in the specimens reinforced with fiberglass/PVC mesh.
