A dynamic test methodology for analyzing the strain-rate effect on the longitudinal compressive behavior of fiber-reinforced composites

This paper presents an experimental study of the strain-rate effect on the longitudinal compressive strength of UD carbon-epoxy IM7/8552 and UD carbon-fiber-reinforced polyamide-6. A test setup for dynamic measurements using a split-Hopkinson pressure bar was developed to achieve valid compressive failure in the specimen’s free gauge section. The setup presented improves on the dynamic compression fixture developed in an earlier study [Koerber...
