A New Method for Determination of Glue Joint Shear-Strength in Laminated Wood
Keywords:Glue joints, shear strength, laminated wood
AbstractCylindrical samples, 3.1 cm in diameter, were used for determination of "strength properties of adhesives in shear by compression loading," Testing was conducted by use of a hand dynamometer (torque wrench). Comparison of the results between cylindrical and standard orthogonal samples (ASTM D905-49) showed that the proposed method can replace the standard method with significant accuracy, and the relationship of values obtained is linear y = 2.19 + 173.19x with coefficient of correlation r = 0.67.
