Heat Shielding of Automotive Components: Chemical Vapor Deposition Aluminized Fabrics Versus Laminated Aluminum Foil Fabrics

Compound materials, consisting of temperature proof glass fiber fabrics and a laminated aluminum layer, are compared in relation to material thickness in the range of up to 200°C to investigate their ΔT behavior under convection heat transmission and radiant heat. Two different technologies for production of 300°C materials are presented, and their advantages and disadvantages are explained. Supported by measurements, this article describes the dependence of the material tensile strength on temperature and temperature cycling.
