Abstract This paper presents the determination of the crack resistance curve of the unidirectional carbon-epoxy composite material IM7-8552 for intralaminar fiber tensile failure under dynamic loading. The methodology, proposed by Catalanotti et al. (2014) for quasi-static loading conditions, was enhanced to high rate loading in the order of about 60 s −1 . Dynamic tests were performed using a split-Hopkinson tension bar, while quasi-static reference tests were conducted on a standard electromec...

The mechanical response of IM7-8552 carbon epoxy was investigated for transverse tension and transverse tension/in-plane shear loadings at static and dynamic strain rates using transverse tension and off-axis tension specimens. The dynamic tests were carried out on a split-Hopkinson tension bar at axial strain rates from 113 to 300 $\hbox {s}^{-1} s - 1 . With the already available off-axis and transverse compression test data for IM7-8552, a comprehensive data set is available now, which can...

Abstract 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 and Camanho, Composites Part A 2011;42]. Gr...

In the presented work, an experimental investigation has been performed to characterize the strain rate dependency of unidirectional carbon fiber reinforced polyamide-6 composite for longitudinal compression loading. An end-loaded compression specimen geometry, suitable for contactless optical strain measurement via digital image correlation and dynamic loading in a split-Hopkinson pressure bar, was developed. For the dynamic experiments at a constant strain rate of 100 s −1 a modified version o...

The mechanical response of the carbon-epoxy material system HexPly IM7-8552 was investigated under transverse tension and combined transverse tension / in-plane shear loading at quasi-static and dynamic strain rates. The dynamic tests of the transverse tension and off-axis tension specimens were carried out on a split-Hopkinson tension bar system, while the quasi-static reference tests were performed on a standard electro-mechanical testing machine. Digital image correlation was used for data re...
