“…Under ultra-low temperatures, researchers conducted static mechanical experiments on the CFRP laminates, such as tensile, compression, and three-point bending [ 6 , 7 , 8 , 9 ]. They found that the interface between the fibers and matrix is strengthened at low temperatures, which improves the static mechanical properties of the laminates.…”

This study uses experimental methods, theoretical research, and numerical prediction to study the dynamic mechanical properties and damage evolution of CFRP laminates at ultra-low temperatures. Based on the Split Hopkinson Pressure Bar (SHPB) device, we set up an ultra-low temperature dynamic experimental platform with a synchronous observation function; the dynamic mechanical properties of laminates were tested, and the damage evolution process was observed. The experimental results are as follows: The compression strength and modulus increase linearly with the increase in strain rate and show a quadratic function trend of increasing and then decreasing with the decrease in temperature. The damage degree of the dynamic bending sample increases obviously with the impact velocity and decreases first and then increases with the decrease in temperature. Based on the low-temperature dynamic damage constitutive, failure criterion, and interlayer interface damage constitutive of the laminates, a numerical model was established to predict the dynamic mechanical properties and damage evolution process of CFRP laminates at ultra-low temperatures, and the finite element analysis (FEA) results are consistent with the experimental results. The results of this paper strongly support the application and safety evaluation of CFRP composites in extreme environments, such as deep space exploration.

“…Overall, the measured TT elastic modulus (E z ) compares reasonably well with published data for polymeric composites with glass and carbon fiber reinforcements in various architectures (woven, unidirectional, bidirectional, 2-D random, and 3-D random) and stacking sequences (8.1-17.0 GPa). 13,19,26,27 This is because, being a matrix/interface dominated property, the fiber properties and fiber architecture are of less importance (unless of course they are z-reinforced or three-dimensional woven).…”

Digital image correlation (DIC) and finite element analysis (FEA) are used to assess the cylindrical spool‐shaped ASTM D7291 and I‐beam‐shaped specimens for through‐thickness (TT) mechanical characterization of thick (~25 mm) fiber reinforced polymer matrix composites. The composites are made of E‐glass woven fabrics reinforcing a vinyl ester matrix. DIC full‐field measurements and FEA showed a rather uniform strain distribution within the gage section of the ASTM D7291 specimen. However, strain concentrations are revealed at the bondlines between the end‐tabs and the test specimen, in addition to strain gradients at the curved section of the specimen. DIC‐measured and FEA‐predicted strain fields of the I‐beam specimens exhibited a region of uniform strain distribution within the gage section larger than that of the ASTM D7291 specimen. Nevertheless, high stress concentrations at the fillet (curved flange‐to‐web transition) regions and some amount of web bending occur in the I‐beam specimen. Beyond providing the TT mechanical properties of the E‐glass woven/vinyl ester composites, the current work discusses advantages and caveats of both promising specimens, providing quantifications of stress concentration factors and length of zones were strains and stresses may be considered uniform.Highlights Stress/strain distributions of through‐thickness tensile specimens are evaluated. The main drawback of the spool‐shaped specimen is adhesive failure. The modified I‐beam specimen shows acceptable stress concentration factors. The modified I‐beam is adequate for strength and Poisson ratio characterization. I‐beam specimens are easier to manufacture and do not require adhesive joints.
