  • Method of evaluating materials using curvature
    Patent number: 7694578
    Abstract: A method of evaluating material properties of polymeric materials includes making one or more material samples or slabs, with each of the samples or slabs having a pair of material layers in contact with one another. The layers are layers of organic matrix polymer material that have different characteristics from each other, for example having a difference in composition and/or cure characteristics. Characteristics of the test slabs and the interface between the layers can be determined by examining curvatures of the test slabs. A number of samples may be made up having the same material in a first layer, and range of different materials in the respective second layers. The range may cover a range of various material compositions and/or cure characteristics.
