Injection moldable thermoplastics filled with various hybrid conductive reinforcements have been investigated for their physical/mechanical properties. The thermoplastics studied include polyphenylene sulfide (PPS), polyether-etherketone (PEEK), and liquid crystal polymers (LCP's). The reinforcements included various combinations and concentrations of graphite (Gr) fibers, stainless steel (SS) fibers, nickel flakes (NiFlk) and nickel plated graphite (NiGr) fibers. Tensile, flexural and drop weight impact tests were performed. Fracture morphology of tensile specimens was investigated using scanning electron microscopy (SEM). The distribution of fibers and flakes was observed using photomicroscopy. Electromagnetic interference (EMI) shielding effectiveness was determined in the range of 15 MHz to 1 GHz. Water absorption, density and electrical resistivity properties were also determined. Differential scanning calorimetry (DSC) was used to determine thermal properties. 6 references.
