Abstract: The application of radar absorbing material focus on the range of hard materials, the flexible radar absorbing fabric made of iron fibers has important research significance in order to meet the special military demand. For the radar absorbing properties and spinning performance of iron fibers, the morphology and micro-elements type and content of the iron fibers were tested, experiments show that cross-section of the iron fiber made of copper production is irregular shaped, multiple longitudinal channels exist, its morphology and composition of the fiber have a catalytic effect on radar absorbing properties. Mechanical properties and friction properties between diameter of 10μm iron fiber and 18μm diameter stainless steel were compared, and the spinning possibility of iron fiber was predicted.

Key words: radar absorbing, iron fiber, microstructure, mechanical property, friction property
