“…The strain rate dependency of matrix-dominated properties of unidirectional carbon-epoxy composites has also been studied (Daniel et al, 2011), and it has been found that the change of the transverse and in-plane shear modulus , transverse tensile and compressive strength and in-plane shear strength could be considered linear with the logarithmic of the strain rate. The influence the strain rate in the transverse modulus of unidirectional carbon-epoxy composites with high fiber content, 65%, was also investigated by (G. Melin & E. Asp, 1999)and the authors found that the average transverse modulus remains constant with the strain rate and the initial transverse modulus decreases slightly with the increment of the strain rate, contradicting the results obtained by (Daniel et al, 2011), who obtained an important increment with the strain rate of the transverse modulus and the strength of samples manufactured by autoclave process.…”

“…They concluded that the extension of the damaged region further away from the fracture surface is larger as the strain rate is higher and that the fiber-matrix debonding tends to be more pronounced when the strain rate is higher. The failure of undirectional carbon-epoxy specimens loaded in the transverse direction was studied by (G. Melin & E. Asp, 1999), concluding that the damage is always initiated by small transverse cracks, independently of the strain rate value. Recently, (Woo & Kim, 2014)used the acoustic emission technique (AE) to study the characteristics of the failure progress in Kevlar-Woven composites, obtaining that the increment of the strain rate causes an increament of the peak stress and toughness, whereas the strain at the peak stress decreases.…”

High performance composites are exposed to severe loading and environmental conditions. In this work, mechanical properties of Fiberglass Reinforced Polyester (FRP) manufactured by resin transfer molding were evaluated. The effect of the strain rate on mechanical properties under three quasi-static testing conditions, four fiber contents and several orientations was studied using instrumented tensile tests. A model was fitted to predict Tensile strength, Young's modulus and shear modulus and the failed samples were analyzed to understand the failure mechanisms. The results showed that the fitted model is reliable enough to conclude about the effect of the fiber volume fraction and the strain rate on the mechanical properties. Young's modulus and tensile strength increased when the strain rate is higher. Tensile strength also increased with fiber content (Vf) up to 41%. The predominant failure mechanism is fiber rupture for the main directions and for the off-axis directions, the failure mechanisms are fiber pullout and delamination.

Abstract. 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 reduction at both strain rate regimes. For the high rate tests, the strain rate in loading direction was adjusted to reach approximately the same strain rate value in the fracture plane for each specimen. The measured axial strengths were transformed from the global coordinate system into the combined transverse tension-shear stress space of the material coordinate system and compared with the Puck Mode A criterion for inter-fibre failure. A good correlation between the experimental data and the predicted failure envelopes was found for both investigated strain rate regimes.

This paper deals with the effect of temperature (room and low temperatures) on the tensile properties at high strain rates of CFRP laminates. Dynamic tests were performed on different carbon/epoxy laminates configurations: unidirectional, [0] 10 and [90] 10 , and quasi isotropic [±45/0/90] S . All these tests were carried out at two temperatures: 20 and 60°C. Validation of Hop kinson bar theory using one dimensional wave propagation theory was performed by analysing the effect of low temperature on elastic wave propagation along the bars of the experimental device, and the subsequent wave dispersion phenomena. The value of the strain on the specimen derived from the signals recorded at the bar gauges was compared with that obtained from a gauge glued on the specimen. All the experimental results of the response of CFRPs at high strain rates and low temperature are analysed and discussed.
