The objective of this research is to characterize the electromagnetic (EM) properties of pultruded composites. The wide range of constituent materials utilized for the manufacture of polymeric composite materials allows these materials to be "engineered" to possess desired EM signatures while maintaining other desired properties such as high strength-to-weight ratio, excellent environmental durability, and good fatigue lifetimes. Pultruded composites that incorporate EM signature materials were manufactured using commercial pultrusion equipment at the University of Mississippi (UM); the bulk permittivity and reflection characteristics of these materials were measured at UM using an HP 85070E Dielectric Probe for rapid measurement of material permittivity in conjunction with an HP8510C Vector Network Analyzer (VNA). Results of this research will be used to fabricate pultruded composites with desired EM signatures.
