Experimental investigation of high strain-rate behaviour of fabric composites

Mechanical properties and energy absorption capability of woven fabric composites under ±45° off-axis tension

“…The results show an increase in tensile strength with increasing strain rate. In [15] the quasi-static and high-rate dynamic ±45°off-axis tensile behaviour of carbon/epoxy plain weave, 2/2 twill weave and 1/8 satin weave fabric composites using a tensile version of SHPB is investigated. It can be observed, that the maximum stress and initial undamaged shear modulus increase with higher strain rates, whereas the failure strain reaches higher values under the quasistatic loading.…”

Experimental study of the impactor mass effect on the low velocity impact of carbon/epoxy woven laminates

“…In this work for a 40 J impact test, the strain rate associated to tensile strength varies from $ 30 s 1 (for the heaviest mass) to $ 60 s 1 (for the lightest mass). This variation has negligi ble influence in the strength properties as Foroutan et al [37] shows. They analysed experimentally the strain rate sensitivity of carbon/epoxy woven laminates under tension, showing a variation of 10% in the tensile strength properties between an static test and a dynamic test at 320 s 1 .…”

“…When intralaminar damage (particularly fibre failure) appears, no influence of impactor mass has been found, even if tensile strength, which is the mechanical property that governs the fibre failure is rate sensitive in woven laminates [37]. In order to explain these differences let's analyse the value of the strain rate in this type of impacts.…”

“…The strain rate effect was found to be not negligible for woven laminates [33,37]. It is possible to find some works [37 40] in which the strain rate sensitivity has been studied, obtaining sensi ble variations in the strength properties.…”

Mechanical and wet tribological properties of carbon fabric/phenolic composites with different weave filaments counts

“…Triki et al [15] found that the mechanical properties of plain weave/chopped strand mat weave are better than that of 4-hardness satin weave/chopped strand mat weave for the thick E-glass/polyester woven fabric composites laminates. Foroutan et al [16] investigated the shear and tensile behaviors of carbon/epoxy composites and Carbon/BMI composites with plain weave, 2 × 2 twill weave and 8-harness satin weave, and then discovered that the shear behaviors are more rate-dependent than their tensile behaviors. Abu Bakar et al [17] explored the elastic properties of woven fabric composites with different weave patterns by finite element method and presented that the geometric characteristics have a significant effect on the elastic properties.…”
