This article describes the use of a dynamic mechanical analysis technique as a monitor for curing behavior in polymeric materials which utilize radiation to initiate curing reactions. This technique is applicable to radiation such as electron beams, ultraviolet light or visible light. In the figure, the sample apparatus includes an oscillator 2 for providing motion of a particular characteristic, such as sinusoidal, to a plaque 3 of radiation-penetrable material. A second plaque 4 is provided and with plaque 3 sandwiches the curable material 6. This composite structure is located in the path of radiation from source 8. Force transducer 10 is connected to bottom plaque 4. In this configuration only one plaque needs to be radiation-penetrable.
