采用改进的组合式压缩剪切夹具，测试不同厚度的蜂窝纸板和高强瓦楞复合纸板横、纵向的剪切载荷-位移数据并绘制了相应曲线以及对应的抗剪切强度柱状图。测试结果表明：对于夹层结构纸板纵向样品的抗剪切能力大于横向样品；在用纸定量和质量相同时，相同方向的蜂窝和高强瓦楞复合纸板的抗剪切能力随厚度的增加而降低，相同厚度和方向蜂窝纸板的抗剪切能力大于高强瓦楞复合纸板，蜂窝纸板的抗剪切性能比高强瓦楞复合纸板更好。研究结果对于夹层结构纸板的进一步应用提供了压缩剪切方面的依据。
採用改進的組閤式壓縮剪切夾具，測試不同厚度的蜂窩紙闆和高彊瓦楞複閤紙闆橫、縱嚮的剪切載荷-位移數據併繪製瞭相應麯線以及對應的抗剪切彊度柱狀圖。測試結果錶明：對于夾層結構紙闆縱嚮樣品的抗剪切能力大于橫嚮樣品；在用紙定量和質量相同時，相同方嚮的蜂窩和高彊瓦楞複閤紙闆的抗剪切能力隨厚度的增加而降低，相同厚度和方嚮蜂窩紙闆的抗剪切能力大于高彊瓦楞複閤紙闆，蜂窩紙闆的抗剪切性能比高彊瓦楞複閤紙闆更好。研究結果對于夾層結構紙闆的進一步應用提供瞭壓縮剪切方麵的依據。

Using the combination compression shear fixture by improving,shear load-displacement data of transverse and longitudinal sample for corrugated composite paperboard (CCP)and honeycomb paperboard with the different thickness were tested and the corresponding shear strength histogram were also drawn.The results showed that:Shear resistance of longitudinal sample is greater than that of transverse sample for the sandwich structure paperboard;Under the same liner and medium,shear resistance with the same direction for the CCP and honeycomb paperboard decreases with increasing paperboard thickness,but the shear resistance of honeycomb paperboard with the same thickness and direction is larger than that of the CCP,so the entirety shear resistance of honeycomb paperboard is better than that of the CCP.The results provide the basis of com-pression shear for the further application of sandwich structure paperboard.
