Properties of Phenol Formaldehyde-Bonded Layered Laminated Woven Bamboo Mat Boards Made from Gigantochloa scortechinii

Wan Nur Shasha Najiha Zainal Abidin et al.

Summary: In this study, laminated bamboo mat boards with five, seven, and nine plies were fabricated using G. scortechinii from Malaysia and evaluated for their physico-mechanical properties, formaldehyde emission, and flammability. The results showed that as the number of ply increased, the density of the laminated boards decreased. The 5-ply boards had the highest modulus of elasticity but the lowest modulus of rupture. The 5-ply and 7-ply boards exhibited better shear strength than the 9-ply boards. The 7-ply boards also showed the highest dimensional stability and all composites were classified as V-0 due to their flame retardant properties.

Utilization of Scots Pine (Pinus sylvestris L.) Timber with Defects in Production of Engineered Wood Products

Daniel Koynov et al.

Summary: This study proposes three gluing methods to utilize defective timber by-products for manufacturing engineered wood panels. These methods enable a more complete and complex utilization of wood with defects. The physical properties (density and moisture content) and mechanical properties (bending strength and modulus of elasticity) of the laboratory-manufactured panels were evaluated according to European standards. The panels manufactured using method 3 and veneered with beech veneer sheets achieved the highest density (643 kg/m3) and bending strength values (28.6 N/mm2). The modulus of elasticity of the laboratory-made panels reached values up to 5580 N/mm2. This study demonstrates the feasibility of utilizing defective wood pieces in the manufacturing of engineered wood panels.
