碳纤维复丝拉伸试样制备过程对拉伸强度测试值的影响OA
Effect of carbon fiber tow tensile specimen preparation process on measured tensile strength
以 7 种碳纤维作为研究对象,通过改变碳纤维复丝拉伸试样制备过程中的张力、固化度和树脂含量,研究制样过程对碳纤维拉伸强度测试值的影响.结果表明:碳纤维复丝拉伸强度的测试值与制样时的张力密切相关;最佳张力与复丝的强度等级的相关性不明显,而与规格有关,规格越大,最佳张力越大;复丝拉伸试样的固化度控制在 94%,树脂含量控制在 40%～45%时,可获得最高拉伸强度测试值.
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 dur-ing the preparation of carbon fiber tows tensile specimens.The results showed that tensile strength values are signifi-cantly 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%.
