The Composites Branch of the Air Force Research Laboratorys Materials and Manufacturing Directorate AFRLRXCC has observed anomalies in Q800 Dynamic Mechanical Analyzer DMA testing of fiber-reinforced polymer matrix composites related to both temperature dependence of the storage and loss moduli and to dependency of these data on specimen thickness using the dual-cantilever beam DCB clamp. Two factors are examined in detail shear area factors used in the DCB stiffness calculations and coefficient of thermal expansion mismatch between the test specimen and the test frame. It is hoped this document will foster technical discussion with original equipment manufacturers of DMA instruments.
