Abstract:

Conductive composites consisting of various thermoplastics filled with conductive chopped fibers have been studied. The thermoplastics chosen were polyphenylene sulfide PPS, polyetherimide PEI, polyphenylene oxide PPO, polyamide Nylon, polycarbonate PC, and liquid crystalline polyester LCP. The chopped fibers included graphite Gr, stainless steel SS, aluminum flake Al Fl, and nickel coated graphite NiGr. Drop weight impact and tensile properties were determined. The effect of fiber loading and type on specific mechanical properties was determined. Photomicroscopy and scanning electron microscopy were performed on several composites noting fiber distribution, orientation and fracture morphology. A laser diffraction technique was used to determine the degree of orientation. Electrical conductivities DC Resistance Method were obtained for various samples. Physical properties such as water absorption, water vapor transmission, and chemical resistance have also been determined.
