Method, device and equipment for testing tensile strength of carbon fiber multifilament and medium

The invention discloses a method, a device, equipment and a medium for testing the tensile strength of carbon fiber multifilaments, and the method comprises the following steps: respectively testing the tensile strength of non-adhesive yarn carbon fiber multifilaments and impregnated yarn carbon fiber multifilaments to obtain first tensile strength and second tensile strength; obtaining a linear relation between the first tensile strength and the second tensile strength according to the first tensile strength and the second tensile strength; adjusting the manufacturing process parameters of the carbon fiber multifilament, taking the carbon fiber multifilament obtained after the manufacturing process parameters are adjusted as a to-be-tested carbon fiber multifilament, and carrying out tensile strength test to obtain third tensile strength; and based on the third tensile strength and the linear relationship, obtaining the fourth tensile strength of the to-be-tested carbon fiber multifilament. According to the
