Abstract

Tensile test is a method used to measure the strength of a material by providing the burden of the opposing forces in a straight line. This experiment used to measure a material’s mechanical strength against a static force which is given slowly. This study discusses on the tensile strength polyacrylonitrile (PAN) membranes made in three variations of the specimen with a mixed composition of different PAN 15%, 17.5%, 20%, in weight). The membrane was created using Sigma Aldrich Polyacrylonitile of polymer fibers and N,N-Dimethylformamide (DMF) as solvent. The process began by mixing the two materials using a magnetic stirrer for 6 hours until the solution is assumed to be homogeneous. The solution wass stored in the bottle airtight and allowed to stand for 24 hours for the next printing. The membrane was keep in storage in tubes desiccator until its water content reduced, then the test can be done. In this study, a machine adhesion terring strength tester was used conducting Strength Test at a speed of 5 mm/min. The test results showed an increase in the value of 359 kPa on the composition of 15%, 473 kPa on the composition of 17.5%, and 653 kPa for the composition of a mixture of 20%.
