Abstract
In this paper, electroless Ni–P plating on polyethylene terephthalatefabrics (PET) with different weight percentage gains was fabricated in the laboratory. The effects of weight percentage gain on the properties of air permeability, electromagnetic shielding performance, sound absorption, thermal stability and tensile were investigated. The results showed that the exponential relationship between air permeability and weight percentage gain could be obtained. Similarly, the linear relationship between fabric thickness and weight percentage gain could be obtained. As the weight percentage gain increased, the shielding effectiveness increased, whereas the surface resistance decreased at first, and then reached to a certain level. When the distance of air gap behind fabric and the frequency of sound wave were given, the sound absorption coefficient increased with increasing weight percentage gain at first, reached a maximum value at the weight percentage gain of 90% and then decreased beyond 90%. The tensile properties of the electroless Ni–P plated polyethylene terephthalate fabric were greatly influenced by the thickness of the coated metal. The linear relationship between tensile strain and Young’s modulus existed.
