Mechanical Wood Properties and Color of Combined PLA- and Thermal-Treated Beech Wood (Fagus sylvatica L.)
European beech (Fagus sylvatica L.) was modified by thermal treatment at 180 °C, oligomeric lactic acid (OLA) impregnation followed by catalyst-free polymerization (120 or 160 °C), and their combined application to evaluate changes in mechanical performance and color. The results for untreated beech wood showed low var...
