“…The intricate geometry of the weave combined with geometrical and material irregularity poses a formidable problem in the modeling and analysis of woven composites. Kollegal and Sridharan examined the behavior of a plain weave lamina subjected to compression (15) . Chapman and Whitecomb studied progressive damage due to cool-down for plain-and stainweave carbon-carbon woven composite (16) .…”

We discuss the cryogenic damage and fracture behaviors of G-11 woven glass-epoxy laminates. In conjunction with the cryogenic fracture toughness test, a finite element analysis was conducted to predict the fracture and deformation for models of the compact tension (CT) specimens. Effective elastic moduli were determined under the assumption of uniform strain inside the representative volume element. Hoffman's criterion was selected as the criterion for fiber-dominated failure, and matrix cracking was detected by the maximum strain criterion. The virtual crack extension method was adopted to calculate strain energy release rate which leads to determination of stress intensity factor. In order to verify the model, correlations between experimental and analytical results were made, in terms of the load-displacement response and the extent of damage growth. Reasonable agreements between the calculations and the experimental data were achieved.

“…At the same time, the undulated areas in this structure create matrix rich areas, and therefore, limit the tensile and compression performance of a laminate. [19,20] Park et al [21] filled theses undulations in a composite laminate based on PVC and a glass fabric with glass fibers in varying length and amount. For low fiber length and concentration of the additional fibers, they were able to demonstrate a slight increase in tensile strength, flexural strength, and inter-laminar shear strength.…”

Woven fabric composites with thermoplastic matrices enable superior mechanical properties with low weight for applications in the field of sports, electronics, aviation, and automotive. In this study, the matrix rich areas of glass fabrics which provide an interlaminar free spacing were modified via in situ melt impregnation of Polyamide 6 (PA6) with varying contents of short glass fibers (sGF). The aim is to effectively use the interlaminar free spacing in a fabric to increase stiffness by filling the matrix rich free spacing with short glass fibers of tailored length distribution. It is shown that 2.6 vol% sGF located in the undulations of the fabric are able to increase the tensile modulus in orientation of the short fibers (sF) by 9% and create an even more pronounced anisotropic enhancement of 14% in compression modulus for both 4.1 and 5.7 vol% sGF and 40% in shear modulus for 2.6 vol% sGF.

“…Zako gave a brief review of the damage analysis for woven composite materials 11 : the modelling work in 12 has considered the geometrical non-linearity without the stiffness degradation, or the whole stiffness was reduced to zero (isotropic damage) 13 ; the anisotropic damage, correspondent to its damage mode, has been applied in [14][15][16][17][18] , but the reduced components and the reduced value are still questionable, as the knowledge was experimentally based. Zako and coworkers 11 proposed to use a theoretical anisotropic damage constitutive equation, the Murakami damage tensor 19 , to represent the damage mechanics, which was implemented on the Gaussian point scale of a meso-FE model.…”

SUMMARYA meso-scale finite element model for static damage in textile composites was established. The impregnated yarn is taken as homogeneous and transverse isotropic material, whose mechanical properties are calculated using Chamis' equations. The damage modes are determined by using the Tsai-Wu criterion and additional criteria. The Murakami damage tensor is used to calculate the post-damage stiffness matrix. The model has been validated using plain weave and twill weave carbon-epoxy composites. The initiation of inter-fibre matrix crack and fibre rupture was analyzed using this meso-FE model.
