摘要：

In order to improve the conductivity of poly (p-phenylene terepahmide) (PPTA) filament yarn, conductive PPTA/polyaniline (PANI) composite yarn was manufactured by an in-situ polymerization-based continuous yarn conductive treatment process. Conductive PPTA yarn reinforced bi-axial, tri-axial and tetra-axial composite materials were prepared by using the conductive PPTA/PANI composite yarn as reinforcement and unsaturated polyester resin as matrix, and then the electromagnetic shielding effectiveness of the composite materials were measured. The results indicate that the surface of PPTA fiber is covered with conductive PANI layer after conductive treatment, the electrical conductivity can reach 1.4-1.9 S/cm, and the mechanical properties of the PPTA filament yarn declines slightly after treatment. The shielding effectiveness value of the multi-axial conductive PPTA yarn reinforced composite materials increases with the axial direction and density of conductive PPTA yarn, when the fabric density is 70/(5 cm), the average shielding effectiveness value of the tetra-axial conductive PPTA yarn reinforced composite material reaches 22 dB in the frequency range from 0.1 GHz to 1.5 GHz.
