Abstract: Using seven types of carbon fibers as the research subjects, this study investigated the influence of specimen preparation on the tensile strength test values by varying the tension, curing degree, and resin content during the preparation of carbon fiber tows tensile specimens. The results showed that tensile strength values are significantly influenced by applied tension during preparation. The optimal tension exhibits negligible dependence on tow strength grade but correlates strongly with tow size, increasing proportionally with larger tows. Maximum tensile strength is achieved at a curing degree of 94% and resin content maintained between 40% and 45%.
