Title

THE EFFECT OF GLUE COVERAGE ON LAMINATES AND THE LAYERING ON SHEAR AND ELASTIC MODULI OF POPLAR WOOD LAMINATED SAMPLE USING A VIBRATION BASED NONDESTRUCTIVE APPROACH

Pages

  550-559

Abstract

 The effect of layering and glue coverage rate in layered products made from poplar wood was studied using non-destructive free vibration test. 120 samples with nominal dimensions of 2.5×2.5×45 cm without any obvious deficiencies and defects were selected and free FLEXURAL VIBRATION in free-free bars were performed on selected samples. Samples were longitudinal cut in three thinner tangential layers and jointed together again using Poly Vinyl Acetate glue. The specimens were divided into four groups according to glue coverage rates, which one group was fully glued and 3 groups were carrying some glue deficiencies in different rates. Manipulated samples were tested again in above mentioned test. Results indicated that shear moduli compare to MODULUS OF ELASTICITY is a more sensitive parameter to evaluate glue efficiencies in laminated beams but concerns remained due to blind points in FLEXURAL VIBRATION nondestructive method.
