APPRATUS AND METHOD OF PREPARING SAMPLE FOR MEASURING PHYSICAL PROPERTIES OF FIBER REINFORCED COMPOSITE MATERIAL

摘要

The present invention includes a reinforcing fiber winding jig in which a reinforcing fiber single tow is wound by a predetermined number of windings, and a molding die for molding by impregnating the wound fiber with a resin, wherein the reinforcing fiber winding jig comprises a main frame and an amount of the main frame and a guide pin installed in the vertical direction at the end to vertically align the yarn when the yarn is wound, wherein the molding die has a forming area defined by an upper block, a lower block, a left block, and a right block, A side support block is coupled to the sides of the left block and the right block, respectively, and a reinforcing fiber winding jig in which the yarn is wound is seated in the right block, and a seating portion is formed to guide the wound yarn to come to the center of the forming area. According to the present invention, it is possible to effectively evaluate the physical properties of a composite material even with a single tow, thereby improving the efficiency and speed of research and development, and It can be used very advantageously for the evaluation of properties for quality control of the produced reinforcing fiber or resin system.
