Abstract : This report includes two projects that were funded under Center of Excellence for Materials Research. In case of Thermomechanics of Fiber-Reinforced Composites, a new apparatus to perform multiaxial thermomechanical tests on small samples has been developed. This report includes our design process, that is, the theoretical ideas and developments that motivated the overall design, the preliminary tests that verified some early hypotheses, the various design alternatives that were considered, and details on the final system that was assembled. In the second project entitled 'High Strain-Rate Behavior and Damage Measurements in Glass-Reinforced Plastics', experimental results are reported over a wide range of strain-rate and in test samples of three orientations. Elastic constants and strengths in two orientations in direction of woven fibers and one perpendicular direction, are reported along with failure mechanisms during quasi-static and impact loading of this material.
