        BMM MachOne 多功能多尺度生物力學(xué)測試分析系統(tǒng) 之

        組織材料植入物塔接結(jié)合力測試分析系統(tǒng) 
        -多載荷多物理場耦合微觀力學(xué)性能原位測試系統(tǒng)

        通過粘合劑粘合在一起的兩層材料被迫彼此滑動(wu剝離),從而在粘合劑層中引起剪切,并終使其破裂。 粘合剪切模量可以通過多種測試方法進行表征。 兩種常見的方法是搭接(測試平面剪切以找到剪切模量和剪切強度)和對接(測試拉伸屈服以找到剪切模量和彈塑性參數(shù))。 平面剪切測試意味著移動的壓板在與粘結(jié)相同的平面中移動。 在這些配置下,樣品被假定為一個完美的矩形,其頂部和底部表面完美地附著在兩個平坦的基板上(防滑邊界條件),盡管此配置也可以記錄粘滑的力與位移數(shù)據(jù) 物理粘附。

        典型應(yīng)用:

        1、夾芯夾層材料剪切性能測試(ASTM C273/C273M - Standard Test Method for Shear Properties of Sandwich Materials)

        2、ASTM D5656-拉伸載荷剪切作用下厚粘劑金屬搭剪連接的應(yīng)力應(yīng)變行為測試

        塔接夾具-低力(帶有凝膠制備室)

        測試膠粘劑的質(zhì)量時,測試膠粘劑沿粘合界面的抗剪切力的重要性能。 在這種情況下,重要的是小化層之間的剝離,這可能會大大降低粘結(jié)的耐搭接剪切強度。 基于專為在硬質(zhì)塑料和金屬部件中實現(xiàn)牢固粘合而設(shè)計的夾具,這些夾具已針對測試生物材料或組織之間的粘合特性進行了化。 它帶有一個te殊的固定器,該固定器旨在促進直接注入兩個壓板之間的水凝膠的原位制備,以大程度地減少暴露于空氣中。 在水凝膠的情況下,還可以測量凝膠的剪切強度及其與壓板材料的粘附性。
