摘要

本研究之目標在於以實驗測試方形紙管承受軸向壓力時其軸向位移對應負載的反應特性，並計算材料之應變－應力曲線。實驗反應觀察，紙管間之脫層現象影響紙管材料強度的變化。由於脫層過程無法控制，造成試件之間的位移－負載曲線及材料的極限應力的變異可達20%；另外各規格尺寸之彈性模數平均值會隨方管尺寸增加而下降。由研究之結果建立方形紙管截面幾何尺寸與極限應力之關係及特性，其可提供後續生產製造品質改進之參考。

The purpose of this research is to test the response characteristics of the axial displacement corresponding to the load when the square tube is subjected to axial pressure, and calculate the material strain-stress curve. Observing the experimental reaction, the paper delamination phenomenon was found to change the paper tube material strength. Due to the fact that the delamination process cannot be controlled, the displacement-loading curve of specimen and the ultimate stress of the material have a variation about 20%. The results of this experiment established the relationship between square paper tube cross section geometric size and ultimate stress, and the reaction characteristics. These provide important reference to the quality improvement of follow-up manufacturing.
