The techniques used to measure, design, and test Radar Absorbing Materials (RAM) are described. Absorbing additives are added to polymer materials at a range of concentrations in the laboratory, and then tested over the frequency range of interest to determine the material’s permittivity and permeability. The techniques and algorithms used to extract these values are dependent upon the material under test and the type of information required.
The techniques used to measure, design, and test Radar Absorbing Materials (RAM) are described. Absorbing additives are added to polymer materials at a range of concentrations in the laboratory, and then tested over the frequency range of interest to determine the material’s permittivity and permeability. The techniques and algorithms used to extract these values are dependent upon the material under test and the type of information required. Once accurately determined, these values are used in a computer optimization code designed to find the best additive concentration and thickness for each layer of a multilayered material to give the highest absorption levels over the user-specified frequency range. The calculated performance from the multilayered material is displayed in real time and has been found to be in excellent agreement with the measured values. Using the techniques described in this report, radar-absorbing materials can be tailor made to suit a wide range of applications, providing Defense with an indigenous capability for high performance RAM products.
The Department of National Defence (DND) in Canada has implemented a revised maintenance program for aircraft weapon systems whose goal is to ensure that essential maintenance is accomplished and to assure the continued airworthiness of aeronautical products during in-service operation. The program especially affects legacy aircraft. A case study is being presented where an adhesion failure was detected during a scheduled inspection.

Protective coating systems provide the primary corrosion protection for assets in sea water. Protective coating systems are defined as a specific combination of surface preparation and coating material applied under specified conditions to a specific structure. Over the past many years, the paint industry has focused considerable resources toward the formulation, performance testing and fine tuning of coatings materials.
