“…The CFRP material in this study consisted of TPU matrix apart from carbon T300 fibres with a fibre volume fraction of 45%. Nicoletto and Riva [21] tested under tension 2/2 twill woven 8-ply 2.4 mm-thick CFRP laminates made of T300 carbon fibres having a fibre volume fraction of 42%. They reported tensile strength of 800 MPa with 1.4% elongation at ultimate load.…”

Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document.Changes In this paper, flexural loading of woven carbon fabric-reinforced polymer laminates is studied using a combination of experimental material characterisation, microscopic damage analysis and numerical simulations. Mechanical behaviour of these materials was quantified by carrying out tensile and largedeflection bending tests. A substantial difference was found between the materials' tensile and flexural properties due to a size effect and stress stiffening of thin laminates. A digital image-correlation technique capable of full-field strain-measurement was used to determine in-plane shear properties of the studied materials. Optical microscopy and micro-computed tomography were employed to investigate deformation and damage mechanisms in the specimens fractured in bending. Various damage modes such as matrix cracking, delaminations, tow debonding and fibre fracture were observed in these microstructural studies. A two-dimensional finite-element (FE) model was developed to analyse the onset and propagation of inter-ply delamination and intra-ply fabric fracture as well as their coupling in the fractured specimen. The developed FE model provided a correct prediction of the material's flexural response and successfully simulated the sequence and interaction of damage modes observed experimentally.

“…Initial cracking was found to occur at approximately 0.4% strain. The overall damage behaviour of non-crimp fabric composites studied by Edgren et al [5] to that of woven fabric composites in which tremendous transverse cracks together with bundle delamination and longitudinal splitting were well observed [8][9][10].…”

“…By using the classical laminate theory, this analytical model takes into account the strand undulations in the two directions and also integrates the geometrical and mechanical parameters of each constituent (matrix, warp and weft yarns). Nicoletto and Riva [15] used the FE method to investigate the mechanical response of twill weave laminates under tensile loading. A microscopic assessment of the failure mechanisms was then conducted.…”

Predicting the Failure Behavior of Textile Composite Laminates by Using a Multi-Scale Correlating Approach

This paper investigates the elastic and failure behavior of textile composite laminates by using an analytical multi-scale correlating approach. The analyses are performed under the four scale levels, i.e. the laminate scale, representative unit cell (RUC) scale, tow architecture scale and fiber/matrix scale levels. The correlation between different scales is derived based on the continuum mechanics and homogenization method from which the stress and strain fields in multiple scales can be obtained concurrently. Effective modulus and ultimate failure strengths of different textile composite (plain weave, twill weave and satin weave) laminates are predicted solely from the corresponding constituent properties, braid geometrical parameters and lay-up. The damage and failure mechanisms at the constituent level are also determined by the micromechanical failure criteria. All the predicted results compare favorably with available experimental data. Parametric studies are also performed to examine the effect of various mechanical and geometrical parameters on the resulting mechanical properties.
