Description

Universal sample preparation device for carbon fiber impregnated yarns and glass fiber impregnated yarns Technical Field The utility model relates to the technical field of sample preparation equipment for reinforced fiber impregnated yarns, in particular to general sample preparation equipment for carbon fiber impregnated yarns and glass fiber impregnated yarns. Background The most conventional and intuitive evaluation method for the mechanical properties of the reinforced fibers is to manufacture the impregnated yarn first and then measure the performances such as modulus, tensile stress, stress-strain relation and the like of the impregnated yarn. At present, the reinforcing fiber impregnated yarn is mainly divided into two major categories, namely carbon fiber impregnated yarn and glass fiber impregnated yarn. However, since the carbon fiber is fed by the outer filament (filament drawing from the outer peripheral surface), the glass fiber is fed by the inner filament (filament drawing from the inner peripheral surface). Therefore, the different structures of the existing carbon fiber impregnated yarn sample preparation device and the glass fiber impregnated yarn sample preparation device are complete, so that the sharing cannot be realized. For example, chinese patent publication No. CN110938953a, which can only be used to make carbon fiber impregnated yarn, but not glass fiber impregnated yarn. Therefore, a general sample preparation device capable of preparing carbon fiber impregnated yarns and glass fiber impregnated yarns is required to be designed, so that the problems of large investment and large occupied area of two sets of sample preparation devices are solved.
