Note (General): This paper describes application of the Moire method to strain analysis of polymers. The mechanical properties of polymers are normally dependent on time and temperature. Especially, the stiffnesses of such materials are greatly effected by temperature. In the range above the“glass transition temperature”, polymers show viscoelastic behavior, become soft and greatly deformed. In the range below the temperature, however, the materials become as hard and brittle as glass. Employing the Moire method, however, makes it possible to measure the large displacement of soft materials without the influence of temperature change or the reinforcing effect. Moreover, strain is easily analysed by differentation of displacement. Therefore, the method can be applied to the displacement or strain analysis of polymers in higher temperature ranges. As an example, the Moire method was applied to the analysis of creep strain, thermal strain and residual strain of epoxy resins. The experimental results indicate that the thermo-mechanical property of epoxy resins in each temperature range can be determined by the Moire fringe patterns, along with the strains obtained by the fringe patterns. The validity of the results were verified by comparison with strains analysed by other methods. Moreover, various applications, limitations and improved techniques of the Moire method are also discussed.
