Analysis of mechanical strength of woven strip composite at petung bamboo (Dendrocalamus asper) epoxy resin tape: tensile strength properties of bamboo strips

Abstract

One of the natural ingredients that have a good prospect to be used as the material of reinforcement of composite material is bamboo. Bamboo in its availability in the territory of Indonesia is quite abundant, as in the area of Tana Toraja South Sulawesi Province. This study aims to see how far the pretreatment can affect the tensile strength of woven bamboo strip composite. The test method used to analyze the tensile strength of bamboo strip composite weaving is based on ASTM D 638-02 standard. The results showed that the duration of immersion affected the tensile strength of the bamboo woven strip composite wherein the treatment of water sulfur immersion the tensile strength was increased with the variation of the duration of immersion time of 1 day, two days, and three days respectively by 89.70 MPa, 125.44 MPa, and 159.01 MPa. While the treatment of soaking water sulfur and continued at seawater immersion treatment with the variation of time immersion time of 1 day, two days, and three days respectively obtained that is 95,92 MPa, 130,69 MPa, and 165,03 MPa. While the tensile strain of bamboo woven strips on immersion of water of sulfur and without immersion of seawater (TPAL) with the variation of immersion time of 1 day, two days, and three days consecutively obtained by 1.58%, 2.00%, and 2.86 %. While the immersion of water sulfur and continued on the immersion of seawater (PAL) with the variation of immersion time of 1 day, two days, and three days respectively obtained by 1.65%, 2.60%, and 3.09%.
