This study was aimed to investigate the bending moment and stress (inner and outer corners) in Lshaped biscuit joint made of solid wood, particleboard and medium density fiberboard (MDF). For this purpose, L-shaped joints made of Beech and Fir, particleboard and MDF by biscuit size numbers of 0 (47×15×3.8 mm), 10 (53×19×3.8mm) and 20 (60×23×3.8mm). Bending moment and stress carrying capacity of the joints were compared to each other. Results showed that bending moment and stress carrying capacity in inner and outer corners of joints were increased by increasing the biscuit size from 0 to 20 (increasing length and wide of biscuit). The Lowest value of these resistance observed in 0 size biscuit. The Results also showed that joints made with Beech were superior to Fir regarding to the measured properties in MDF and particleboards.
