Role of Aluminum (Al) Thin Film in the Improvement of Anti-Permeation Behavior of Fabricated Composites in Corrosive Environment

Abstract

Though composites, particularly those consisting of organic materials, have replaced the role of traditional metallic materials in various engineering applications due to their relatively high mechanical strength, low density, flexibility and low cost, their disadvantages caused by relatively high porosity ratio and low crystallinity inherently make this kind of materials the less favorable choices when low permeation property is a major criterion. Here pure aluminum (Al) thin film, which has excellent anti-corrosion property, is introduced into the structure of fabricated composites to improve the composite’s anti-permeation behavior in corrosive environment while the advantageous points of organic composites are exploited at the same time by applying the optimized thermo-mechanical processing techniques in fabrication. Thus greater potentials for organic polymeric composites may be achieved in the future.
