Abstract
Description
・テストされる人は、21℃および45%rhの気候室の中で15分の間に順応させられる。
・テストは、21℃および45%rhの気候室の中で実施される。
・DiaStron製のMTT170引張試験機
・調節可能なアームレストチャネル
・ソフトウェアMTT Win(UvWin1.32.000)
・クランプ1:引張試験機の上・ Clamp 1: on 前記tensile tester
・クランプ2:カウンターウェイト、60g
・0.9重量%NaCl溶液(150ml/材料ストリップ)
・打ち抜き、30*350mm
F摩擦=F乾燥+F粘着 (式1)
F粘着=Fウェット接触+Fウェット細孔 (式2)
F摩擦(s)=F乾燥×C乾燥+Fウェット接触×Cウェット接触(s)+Fウェット細孔×Cウェット細孔(s) (式3)
ここで、sは、境界面における飽和の程度であり、Cは、相互作用の発生である。
