CORE DELAMINATION AND SHEAR TESTS FOR LAMINATED WOOD,

Abstract

A delamination and a shear test method using small cores drilled from wood laminates provide for non-destructive and potentially low cost testing of glueline quality throughout the length and depth of laminated wood members. Cores 3/8 in. diameter obtained from the full depth of laminates by means of a special core drill are subjected to 16-24 hours of a 45 minute wetting and drying cycle in an automatic cycler to give a measure of delaminations resistance. Similar cores for determination of shear strength and wood failure employ a tool adapted to a standard cross section 12-day test method and block shear together with proposed round robin standardization.
