A rapid and flexible material characterization system ispresented. With this computerized testing module, thermally expansionaland monotonic tests have been conducted to determine the elasticbehavior of thin epoxy FR-4/ E-Glass woven laminates under differenttemperature levels. In this research the electrical resistance straingauge technique is used to evaluate the test methods for differentmaterial properties. This includes two main steps for each temperaturelevel. First is to test thermal expansions under stress-free conditionsand then to test linear elastic constants in two dimensional cases. Thethin laminates are assumed to be linear and orthogonal. Thetemperature-dependent properties of interest are coefficients of thermalexpansion (CTEs), Young's moduli, shear moduli, and Poisson's ratio. Thetemperature levels ranged between 23° C and 150° C, which ishigher than the glass transition temperature (Tg), 125° C,of the tested material. The setup, the features and the capabilities ofthe automated material testing system are also discussed
