[0051] The tensile characteristic evaluation according to one embodiment of the present invention may be performed by fixing the lower tensile module (200) to the ground or the fixed surface and then applying force to the upper tensile module (100) connected to the device providing tensile force from the outside, or by connecting the upper tensile module (100) and the lower tensile module (200) to the device providing tensile force from the outside and then applying force.

[0052] The device for providing a tensile force from the outside according to one embodiment of the present invention can evaluate the tensile characteristics of the FRCM composite (1) by providing a tensile force to either the upper tensile module (100) or the lower tensile module (200), or by providing a tensile force to the upper tensile module (100) and the lower tensile module (200). The device for providing a tensile force from the outside may include a tensile tester that provides a tensile force using an electric motor, a hydraulic pump, or the like, and the tensile tester included in the device for providing a tensile force from the outside is not limited thereto.

[0053] According to another embodiment of the present invention, a jig (10) for evaluating the tensile properties of the FRCM composite can measure the influence due to the eccentricity of the FRCM composite (1) by asymmetrically applying the same force to the upper tensile module (100) and the lower tensile module (200) with respect to the center of the FRCM composite (1) when evaluating the tensile properties of the FRCM composite (1), thereby adding an eccentric load to the FRCM composite (1).

[0055] According to another embodiment of the present invention, a jig (10) for evaluating the tensile properties of the FRCM composite can apply an eccentric load to the FRCM composite (1) by changing the installation positions of the first fastening portion (140) and the second fastening portion (240) by differently increasing or decreasing the lengths of both sides of the first tensile force transmitting portion (120) and the second tensile force transmitting portion (220) to change the inclination of the first support portion (130) and the second support portion (230).

[0056] For example, when the lengths of the first tensile force transmission unit (120) and the second tensile force transmission unit (220) located close to the first fastening unit (140) and the second fastening unit (240) increase, the lengths of the first tensile force transmission unit (120) and the second tensile force transmission unit (220) located in the opposite direction decrease, and accordingly, the first support unit (130) and the second support unit (230) may tilt in the direction in which the lengths of the first tensile force transmission unit (120) and the second tensile force transmission unit (220) decrease. At this time, the tilts of the first fastening unit (140) and the second fastening unit (240) connected to the device that provides the tensile force from the outside do not change.

According to another embodiment of the present invention for this purpose, the first tilt adjustment member (131) and the second tilt adjustment member (231) may include a connecting member such as a torque hinge, and the connecting member included in the first tilt adjustment member (131) and the second tilt adjustment member (231) is not limited thereto.

[0058] According to another embodiment of the present invention, a jig (10) for evaluating the tensile properties of the FRCM composite may further include a displacement measuring unit (not shown) for measuring displacement resulting from the evaluation of the tensile properties of the FRCM composite (1).

[0059] According to another embodiment of the present invention, the displacement measuring unit is installed at the center of the FRCM complex (1), and when the FRCM complex (1) is deformed by receiving the tensile force, the displacement of the FRCM complex (1) can be measured by measuring the changed resistance of the displacement measuring unit. For this purpose, the displacement measuring unit may include a displacement sensor such as a strain gauge, and the type of the displacement sensor included in the displacement measuring unit is not limited thereto.

[0060] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will readily appreciate that the present invention can be readily modified into other specific forms without altering the technical spirit or essential characteristics of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single entity may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined manner.
