Equipment Overview:

       Microcomputer-controlled composite testing machine is mainly used for tensile, bending, compression, shear, crack propagation and other mechanical properties of composite materials。With three closed-loop control methods of stress, strain and displacement, the maximum load, tensile strength, bending strength, compressive strength, shear strength, elastic modulus, elongation at break, Poisson ratio and other parameters can be calculated。Test and provide data according to national standards and ISO, JIS, ASTM, DIN and other international standards。

特点：

• The main machine is a floor door structure, and the middle beam is guided by a high-precision guide bar, which has high rigidity and good linear motion characteristics.

• The equipment is equipped with high and low temperature environment box, full temperature stretching fixture, video extension meter, which can complete the full-field strain test under high and low temperature environment of -70-350C;

• The coaxiality adjustment device can provide good coaxiality accurately and effectively;

• Using circular arc silent synchronous belt and imported AC servo motor, with well-designed transmission mechanism, high efficiency, low voice;

• Automatic switching control mode: In the case of stress rate control, it can be automatically switched to the displacement rate control mode according to the test requirements of the material;

• With overload, overcurrent, overvoltage, limit and other safety protection modes;

• With calibration and linear correction function, load and displacement can be automatically calibrated。
