Studies on laminated and scrimber composites produced from thermally modified D. strictus bamboo bonded with melamine-based adhesive

Bamboo culms of Dendrocalamus strictus (Roxb.) were subjected to thermal modification at different treatment temperatures of 160, 180 and 200 degrees C under partial vacuum. Control and thermally modified bamboos were converted into strips and crushed strands to produce laminated (LBL) and scrimber...
