Product Details：

Introduction:

A rectangular coated fabric sample is sewn into a cylindrical shape, and the coated fabric cylinder is placed between two disks and fixed in position. One of them oscillates at 90° on the shaft, which causes Coated fabric cylinder samples to cause twisting. At the same time, the other disc reciprocates along its axis, compressing the cylindrical specimen along its length. This twisting and compression of the cylindrical specimen continues until the predetermined number of cycles of the specimen is significantly damaged.
