Device for determining the tensile strength of the polymer composite reinforcement

摘要

The invention relates to a device for determining the mechanical properties of materials, particularly - a device for determining the tensile strength of the composite polymer valves used in construction. The apparatus comprises a frame, nagruzhatel, fixed and movable rod attachment points is provided with a rotary side scene linking frame with nagruzhatelem, the mobile node attachment is mounted on the wings, and each of the attachment is designed as a profiled lodgements with U-shaped grooves, the length of which are mounted clamping lining. The entrance angle of the reinforcing bar in the U-shaped channel is 0 ° to the axis of the working portion, and then increased every 10-20 diameters at 5-10 °. EFFECT: improved accuracy, and increase technological efficiency test tensile polymer composite reinforcement. 3 yl.
