Evaluation of Mechanical Properties and Formaldehyde Emission of Plywood Manufactured for Construction Applications

This study was aimed to evaluate some mechanical properties and formaldehyde emission of beech plywood panels manufactured from rotary cut veneers using phenol–formaldehyde (PF) resin. Six plywood panels of 5 plies with 15 mm thickness were manufactured. Modulus of rupture (MOR), modulus of elastici...
