“…Therefore, investigation of carbon fiber under cryogenic condition is very critical to reveal the mechanism of tensile behavior of CFRP in extreme low temperature. 13 Among carbon fibers produced by different precursors, polyacrylonitrile (PAN)-based carbon fibers are the most widely used ones due to their excellent mechanical properties and cost effective quality. [14][15][16] PAN precursor fiber is mainly manufactured by two relatively mature processes: dry-jet wet spun and wet spun.…”

For carbon fiber-reinforced polymer composites applied in aerospace industry, the mechanical performance of carbon fiber in extreme temperature environment is of great importance. In this study, carbon fiber produced by dry-jet wet spinning and wet spinning approaches were cryogenically conditioned at different cooling rates. After cryogenically conditioned at sharp cooling rate, both fibers have around 10% decreases in tensile strength due to the huge hoop stress induced by the quenching process. However, after cryogenically conditioned at slow cooling rate, the interfacial shear strength between the two kinds of carbon fibers and epoxy resin was significantly enhanced. Furthermore, scanning electron microscopy, atomic force microscopy, and the Raman spectroscopy were conducted to detect the microstructures and surface morphologies of the cryogenically conditioned carbon fibers. This study provided fundamental data for the material design and application of the carbon fiber at extreme temperature environments such as aerospace or other industrial fields.

“…The longitudinal strength values of fibre yarn show a larger discrepancy between the theory and numerical analysis, since the equations for strength prediction are empirical and depend heavily on the mathematical model of fibre arrangement [42]. The disparity can be justified employing our previous experimental study [27]: the tensile strength value of yarn, ranges from 2.6 to 3.81 GPa, depending strongly on the chosen gauge length. The average value of the experimental results is approximately 3.29 GPa.…”

“…In this study, a micro-scale model was first built with hexagonal arrays of fibres to obtain effective elastic constants and strengths of yarns under different loading conditions. The input data for the micro-scale model were experimentally measured in our previous work [27,28]. The results of micro-scale modelling were used as input for material properties of the meso-scale model.…”

“…For the purpose of modelling the failure strength, we assume that the magnitude of 3 E for all materials is equal to the modulus in the compacted state, and approaches the transverse modulus of the fibre (i.e. 10 GPa for PAN-based carbon fibre, as reported by Ji et al (2015)), see Table 2. Numerical experimentation, as well as a consideration of the analytical model, shows that f p is insensitive to the magnitude of the moduli of the plies and of the inter-layers.…”

The effect of matrix shear strength on the out-of-plane compressive strength of CFRP cross-ply laminates

The failure mechanism of 'indirect tension' is explored for cross-ply IM7/8552 carbon fibre/epoxy laminates subjected to quasi-static, out-of-plane compressive loading. The sensitivity of compressive response to strain rate and to the state of cure is measured, motivated by the hypothesis that the out-of-plane compressive strength is sensitive to the matrix shear strength. A pressure-sensitive film is placed between specimen and loading platen, and reveals that a shear lag zone of reduced compressive traction exists at the periphery of the specimen, giving rise to a size effect in compressive strength. The width of the shear lag zone reduces with increasing shear strength of the matrix. The laminates fail by the indirect tension mechanism: out-of-plane compressive loading generates tension in the fibre direction for each ply and ultimately induces fibre tensile failure. Finite element (FE) simulations and an analytical model are developed to account for the effect of matrix shear strength, specimen geometry, and strain rate on the out-of-plane compressive strength. Both the FE simulations and the analytical model suggest a recipe for increasing the through-thickness compressive strength.
