Effect of the Flexural Strength on Finger-Jointed Wood with 25 mm Finger Length and 19 mm Finger Length

Timber is a renewable resource and is widely used for furniture manufacturing and construction industry in the world. Finger Joint is an effective method to minimize the timber wastage arising in the timber-related industries. This study was undertaken to effect of the bending test on finger-jointed wood with 25 mm finger length and 19 mm finger length. For bonding purposes, SWR adhesive (PVAc) D3-type glue was used at normal exposure conditions. Well-seasoned, defect-free wood materials from seven timber species; Grandis, Jack, Kumbuk, Mahogany, Pine, Satin, and Teak were selected for this study. BS 373:1957 was used as a standard for tests. Mechanical properties were performed by the Universal Testing Machine (UTM 100PC). Results were analyzed using ANOVA. Results revealed that there is a significant relationship between MOR and finger length (P < 0.05) and there is no significant relationship between MOE and finger length (P > 0.05) and can be recommended, horizontally oriented 19 mm finger-jointed specimens suitable for finger joint applications than 25 mm finger-jointed specimens.
