“…In the failure analysis process, the failure state of the interface is evaluated by the failure of fiber and matrix that is adjacent to the interface. Similar modeling methods are explained in reference [7]. Henceforth, the term "composite tows" is refers straight fiber tows impregnated with resin.…”

“…For the mechanical analysis of NCF composite structures, the basic mechanical properties of the semi-laminar composites should be known. To obtain the mechanical properties of each lamina of quadriaxial non-crimp fabric (QNCF) composites (the material is supplied with a layer stacking sequence (45 • /90 • /−45 • /0 • )) through experiment, four kinds of UD specimens need to be produced (one for each fiber direction, including the through-thickness yarn) [7]. This process is very complicated and costly, for it is not very easy to adjust the warp-knitting machine for a small batch production of these UD specimens.…”

Quadriaxial non-crimp fabric (QNCF) composites are increasingly being used as primary structural materials in aircraft and automotive applications. Predicting the mechanical properties of QNCF lamina is more complicated compared with that of unidirectional (UD) composites, because of the knitting connection of different plies. In this study, to analyze the stiffness and strength of the QNCF composites, a novel modeling strategy for the meso-scale features is presented based on the semi-laminar assumption. Following the view of the mechanical properties of single composite lamina, the complex QNCF layer is decomposed into individual plies. Three different representative unit cells along fiber direction are selected to predict the mechanical performance of QNCF, including in-plane stiffness, damage initiation, and stiffness degradation. To validate the developed modeling strategy, the predictions are compared with existing experimental results, where a good agreement is presented on the prediction of in-plane stiffness and strength. Furthermore, the effect of in-plane fiber distortion, induced by the stitching yarn on the mechanical properties, is studied.

“…Woven-fabric composite laminates offer a number of attractive properties compared to their unidirectional-tape counterparts such as lower production costs, better drapability, good resistance to fracture and transverse rupture due to weaving resistance, and high impact strength [1,2]. These properties have attracted the sports industry to incorporate woven CFRP laminates in the design of sporting goods.…”

Carbon fibre-reinforced polymer (CFRP) composites are widely used in aerospace, automotive and construction structures thanks to their high specific strength and stiffness. They can also be used in various products in sports industry. Such products can be exposed to different in-service conditions such as large bending deformation and multiple impacts. In contrast to more traditional homogeneous structural materials like metals and alloys, composites demonstrate multiple modes of damage and fracture due to their heterogeneity and microstructure.

Carbon fibre-reinforced polymer (CFRP) and glass fibre-reinforced polymer (GFRP) woven composites are widely used in aerospace, automotive and construction components and structures thanks to their lower production costs, higher delamination and impact strengths. They can also be used in various products in sports industry. These products are exposed to different in-service conditions such as large tensile and bending deformations. Composite materials, especially ±45° symmetric laminates subjected to tensile loads, exhibit significant material as well as geometric non-linearity before damage initiation, particularly with respect to shear deformations. Such a nonlinear response needs adequate means of analysis and investigation, the major tools being experimental tests and numerical simulations. This research deals with modelling the nonlinear deformation behaviour of CFRP and GFRP woven laminates subjected to in-plane tensile loads. The mechanical behaviour of woven laminates is modelled using nonlinear elasto-plastic as well as material models for fabrics in commercial finite-element code Abaqus. A series of tensile tests is carried out to obtain an in-plane full-field strain response of [+45/-45]2s CFRP and GFRP laminates using digital image correlation technique according to ASTM D3518/D3518M-94. The obtained results of simulations are in good agreement with experimental data.
