Production of long metal fibers using a combined method of microsaw turning and pulling

The performance of metal fibers, such as the roughness of their appearance, the length, the strength and the diameter are very important when they are used as filling and intensifying material of composites. How to control the performance of metal fibers in a simple and economical way when producing metal fibers has attracted attention for decades. In this paper, a new method which combines microcutting and pulling is put forward and has found application in producing long metal fibers. The main technical parameters which affect the characteristic of long metal fibers are discussed and the proper values to achieve good performance of the metal fibers are obtained with low carbon steel as the raw materials.
