Abstract

The invention relates to the field of fiber enhanced resin base functional composite materials, in particular to a nickel plating glass fiber fabric and a method for preparing an epoxy resin electromagnetic shielding composite material with the nickel plating glass fiber fabric as a functional material. Firstly, the glass fiber fabric is subjected to surface pretreatment, so that the surface of the glass fiber fabric has certain catalytic activity. The specific pretreatment technology comprises the steps of oil removing, roughening, sensitization and excitation. Then, the surface of the glass fiber fabric is plated with metal nickel through a chemical plating method. The prepared nickel plating glass fabric is immersed in an epoxy resin base body, and the electromagnetic shielding composite material is prepared through a laminating forming method. Or, the prepared nickel plating glass fiber fabric is laid in the die, and then the epoxy resin electromagnetic shielding composite material is prepared through the RTM forming technology. The volume resistivity of the prepared electromagnetic shielding composite material is 10<-3>omega.cm, the shielding effectiveness can reach 60dB or above within the frequency range of 2-18 GHz, and good mechanical performance is achieved.

Description

technical field [0001] The invention relates to the field of fiber-reinforced resin-based functional composite materials, in particular to a method for preparing a nickel-plated glass fiber fabric / epoxy resin electromagnetic shielding composite material. Background technique [0002] Nickel-plated glass fiber fabric has multiple properties of metal nickel and glass fiber fabric, such as low density, high conductivity, flexibility, corrosion resistance and high mechanical properties, so it not only plays a huge role in the traditional shielding field, And it also has a very broad application prospect in the field of conductive materials. Conductive composite materials and electromagnetic shielding composite materials prepared with metals as conductive fillers cannot be widely used due to the disadvantages of high cost and high density. Therefore, the properties of different materials are organically combined to prepare low-cost, low-density high-conductivity composite materia...
