Preparation and Characterization of Radar Wave Absorbing CB/PP Fibers
The compound fibers were melt-spun by co-extrusion of polypropylene and polypropylene/ fillers master-batches. The melt-spun fibers were characterized by DSC, SEM and MSERA. Crystallinity of compound fibers with carbon black (CB) was more than that of PP alone. SEM results showed that inorganic particles in fibers had relatively good dispersibility. The electrical resistance of fibers containing CB particles reached minimum at the 10 Wt% CB content. Fibers with CB showed the good radar absorption effects and the absorption property was improved with the increase in CB content.
