IMPROVEMENT IN FLEXIBILITY OF LAMINATED VENEER LUMBER BY USING PRESSURE-SENSITIVE ADHESIVES

摘要

The flexibility of LVL by using four kinds of commercial adhesives: epoxy resin (EP), polyvinyl acetate emulsion adhesive (VA), silicon elastomer adhesive (SI) and acrylic pressure-sensitive adhesive (AC) was evaluated by dynamic mechanical thermal analysis and bending test. As a result, As a result, the glass transition temperature (Tg) of the LVL depended on that of the adhesives applied, where the order of Tg was AC
