Abstract

The invention relates to sample preparing and tensioning equipment for performance testing of a tensile sample strip of a carbon fiber multifilament. The equipment comprises a horizontally arranged bottom plate, wherein a stretching module is arranged on the bottom plate and comprises a first pressing assembly and a second pressing assembly which are used for fixing a carbon fiber tow; a sliding assembly is arranged below at least one of the first pressing assembly and the second pressing assembly so as to allow the pressing assembly provided with the sliding assembly to move in the extending direction of the carbon fiber tow, and the end, where the movable pressing assembly is located, of the stretching module is a stretching end; a transmission structure and a driving device are arranged on the bottom plate, and the transmission structure is in transmission connection with the stretching end of the stretching module; and the output end of the driving device is in transmission connection with one end of the transmission structure. According to the equipment provided by the invention, the carbon fiber tow can be conveniently tensioned, and the tensioned carbon fiber tow can be conveniently subjected to dipping treatment, so the standard of a manufactured test sample piece is ensured, and the accuracy of a test result of the test sample piece is ensured.

Description

technical field [0001] The invention belongs to the technical field of performance testing of composite materials, and in particular relates to a sample preparation and tensioning device for performance testing of carbon fiber multifilament tensile samples. Background technique [0002] Carbon fiber mainly refers to a new type of material composed of carbon-carbon chemical bonds with excellent properties such as heat resistance, thermal shock resistance, corrosion resistance, heat conduction, and easy conduction. Carbon fiber composite materials were first used in the fields of rockets and aerospace, but with the rapid development of the technology for preparing composite materials, carbon fiber composite materials have been widely used in automobiles, wind power, sports equipment, medical equipment and other fields in recent years. [0003] The parameters for evaluating the mechanical properties of carbon fiber composites mainly include tensile strength, tensile modulus, el...
