Influences of weaving architectures on the impact resistance of multi-layer fabrics

Impact Resistance of Plain and Twill Fabric in GFRP Measured by Active Thermography

“…They are mostly created in order to obtain a composite with resistance to various types of loads [7].Versatility of composites of UD fabrics translates into the increased vulnerability to fracture toughness and inter-laminar delamination at low-energy impact in relation to woven fabrics [8]. Composites made with woven fabrics produced by means of textile weaving differ from one another by tensile modulus, tensile strength, flexural strength, flexural modulus and interlaminar shear strength, as well as the smoothness of fabric [9,10].Plain or twillweave fabrics are most commonly used in industrial condition [11].Plain weave fabric, i.e. cloth fabric, is produced when weft fibre strands are interwoven between warp fibre stands.…”

Three-dimensional Voronoi model of a nacre-mimetic composite structure under impulsive loading

“…Consequently, the demand for lightweight high-performance materials has increased significantly in protective structural engineering. Biological structures, meta-materials, woven fabrics, nano-polymers, composite sandwich panels and many others have recently been investigated by structural research engineers because of their unique mechanical characteristics, which make them suitable under a range of extreme applications, namely blast, ballistics, fire and so on [3][4][5][6][7][8][9][10]. In particular, the two-layer armour system (Fig.…”

A method for inter-yarn friction coefficient calculation for plain wave of aramid fibers

“…E 1 was obtained by uniaxial traction test and E 2 , E 3 , G 12 , G 13 and G 23 were calibrated taking suggestions from the model by Rao et al [9] and Yang et al [15]. It has been proved that Poisson's ratios ( 12 , 13 , 23 ) should be zero and the transverse Young's modulus (E 2 , E 3 ) and shear modulus (G 12 , G 13 , G 23 ) should be very small with respect to the longitudinal Young's modulus E 1 to reproduce a thread behavior for the yarn [16].…”
