Bonding Strength between Cross Layers of CLT Evaluated by Torsion and Compression Block Shear Tests Open

Wataru Ishihara, Ryuya Takanashi, Yoshinori Ohashi, Junko Miyazaki, Shoichi Nakashima , et al. · 2021

直交集成板 (CLT) における直交接着層 (直交層) の接着強度を評価するために,直交層のねじり試験,JAS 3079に拠るブロックせん断試験,繊維方向に対して45度の方向から加力したブロックせん断試験の3つのせん断試験を行った。その結果,いずれの試験においても,使用する接着剤の違いによるせん断強度の差異はないこと,試験片の気乾密度とせん断強度に正の相関があることが示された。試験片の気乾密度とせん断強度の回帰直線より得られるせん断強度を比較すると,JASブロックせん断試験…
