“…These have the flexibility of design and superior manufacturing over other materials [11][12][13][14]. Recently, as the need for the development of new materials is increasing, high-performance multi-functional composites are being actively developed with properties such as lightweight, heat resistance, electrical conductivity, vibration damping, and dimensional stability [15][16][17][18][19].…”

In this paper, the bending properties of woven carbon/glass and carbon/aramid fabric-reinforced polymer laminates is studied using a combination of experimental analysis and fracture observation. Six types of each hybrid composite were manufactured by lamination of the carbon/aramid fabric and carbon/glass fabric using VARTM. Bending behaviors were fundamentally evaluated for the six types of monolithic composites laminated by the same fabric. The objective was to achieve a good bending strength by effective combination of composite structures using limited amounts of a raw material. It was shown that the bending property was different, depending on the type of fiber, lamination structure, and the number of layers.

“…Recently, X-ray micro-computed tomography (micro-CT) (Rinaldi et al, 2012;Djukic et al, 2013) was utilized to determine the internal structural variations, and the measured geometric information was directly implemented in a textile software such as WiseTex (Verpoest and Lomov, 2005) to create a mesoscale textile model. It has been reported previously that the damage and failure of the constituents in the mesoscale model can be captured via a stiffness degradation scheme based upon continuum damage mechanics (CDM) (Hufenbach et al, 2004;Kurashiki et al, 2007;Gorbatikh et al, 2007;Ivanov et al, 2009). Although modeling the exact textile geometry is possible using a computer-aided drawing software, the model usually encounters difficulty in the subsequent finite element analysis (FEA) if the fiber tows are interacting with each other (Pankow, 2010).…”

a b s t r a c tA mechanics based multiscale computational model is presented to predict the deformation, damage and failure response of hybrid 3D textile composites (H3DTCs) subjected to three-point bending. The geometry of the textile architecture was incorporated in a mesoscale finite element (FE) model, while the H3DTC was homogenized at the macroscale. The mesoscale model is a collection of repeat unit cells (RUCs) that are composed of different types of fiber tows embedded in a surrounding matrix. Matrix microdamage was modeled by a (pre-peak) nonlinear stress versus strain response, using a modified J 2 deformation theory of plasticity incorporating a secant-modulus approach. Fiber tow pre-peak nonlinear response was computed using a novel, two-scale model, in which the subscale micromechanical analysis was carried out in closed-form based upon a unit cell of a fiber-matrix concentric cylinder. Consequently, the influence of matrix microdamage developing at the microscale manifests as the progressive degradation of fiber tow stiffness at the mesoscale. The smeared crack approach (SCA) was employed to model the post-peak softening of the constituents due to failure, including matrix macro-cracking, tow kinking, and tow breaking. This method offers a mesh objective result by relating the post-peak softening response to a traction-separation law that is associated with each failure mechanism through a characteristic length. Thus, the total energy release rate during failure in a continuum element is related to the fracture toughness of the material.The load-deflection responses, along with the progressive damage and failure events, including fiber tow kinking and rupture, are successfully predicted through the proposed computational model. In addition, the textile architecture-dependent effect, observed in the asymmetric H3DTCs, is also captured, demonstrating the predictive capability of the proposed modeling scheme. Since all the inputs are from the constituent level, the model is useful in understanding how the macroscopic response of H3DTCs is influenced by textile architecture and constituent properties. The experimental studies are presented in Part I of this two-part sequence Zhang et al., in press.

“…Various NDT techniques and damage assessment methods are used for material model verification purposes or simply to achieve a better understanding of damage growth in composites. Crack density measurements [2,3], micrograph analysis [4,5], acoustic emission [6][7][8], thermography [9], ultrasonics [10,11] and video studies [6] are among the different used approaches. Their advantages and disadvantages are widely reported in the literature.…”
