A comprehensive performance test platform for axial tension, bending, torsion, and vibration of a composite material, comprising a tension unit, a bending unit, a torsion unit, and a vibration unit. A fixed end (100) of a clamping device is fixed on a workbench (10); a movable end (200) of the clamping device is fixed on the torsion unit; bending loading of a test sample is realized by the bending unit; vibration of the vibration unit is caused by eccentric rotation of a workpiece caused by the bending unit. The performance test platform integrates static tests of three single-load loading and multi-load composite loading of tension, bending and torsion, and can realize rotating motion in any combination of tension, bending and torsion, provides an effective test platform for researching the influence of multiple loads on the performance of a material and a change rule of other performance parameters, and solves the problems in the prior art of complex operation, poor compatibility and the like.
