Abstract:

The limiting value of thermal porosity for Al-coated fabrics appears to be about 25. Any subsequent improvement would come from using a metallizing process where the substrate would not be exposed at a normal angle to metal vapors, but where it would be exposed in such a way that the vapors would coat all of the surface of the yarn uniformly. All substrates show a marked decrease in the breaking strength of the fabric after cleaning, an operation which removes oils and plasticizer films as a prerequisite to metallizing. Abrasion tests indicate that wear does not materially decrease the efficiency of metallized fabric as a barrier to thermal radiation, since most effective abrasion takes place at the contact points only. Metallizing both sides of a substrate decreases the thermal porosity of the substrate significantly. The thermal porosity of a fabric decreases more than 5 when Au or Ag metallizing is substituted for Al.
