Embodiment Construction
[0033] Embodiments of the present invention provide a graphene rubber strain testing device and a rock strain measuring method, such as Figure 1-6 As shown, it is used to measure the radial strain and axial strain of the rock test block 1, including a graphene rubber strain gauge 2, a data collector 3, and a display 4 connected in sequence.
[0034] The graphene rubber strain gauge 2 includes a graphene rubber strip 21, and the graphene rubber strip 21 is formed by mixing graphene and elastic rubber. Graphene is mixed into rubber with good elasticity, and the rubber is natural rubber, so that when the graphene rubber strip 21 is deformed, the graphene content on the cross section of the graphene rubber strip 21 changes, and the amount of current passing through also changes, and the change of its resistance is measured rate, to achieve the purpose of measuring the strain of the object conveniently and quickly.
[0035] like image 3 As shown, the two ends of the graphene ru...
