Abstract

The development demand for lightweight and low dielectric properties of resin based wave-transparent composite materials. This article replaces traditional glass fibers with PBO fibers with lower dielectric constant and lower density as the reinforcement material for wave transmitting composite materials. To improve the mechanical properties of PBO reinforced cyanate ester composite materials, a plasma process was used to modify the surface of PBO fiber fabric. The influence of plasma process on the surface chemical composition, microstructure, and mechanical properties of PBO fiber was analyzed. The interlayer shear strength of PBO/CE composite materials was increased by 45%, and the interlayer shear strength was 29.8 MPa. The modified fiber composite material has a dielectric constant of 3.3 and a loss tangent of 0.005 at 10GHz, exhibiting excellent dielectric properties. The tensile strength at room temperature of the composite material is 591MPa, and the bending strength is 336MPa, indicating good comprehensive mechanical properties. As a new type of transparent composite material, it has broad application prospects in fields such as aircraft, missiles, satellites, sea-based and land-based radar radomes, as well as high-performance printed circuit boards.
