“…Moreover, relative humidity has a great influence on the tow-tow COF with sizing, but not without sizing. Sizing has also been shown to have an influence on the creep compaction behaviour of dry fabric when the temperature varies (25 and 160°C), while the behaviour of unsized fabric does not change [23].…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. A B S T R A C TCarbon fibres are sized for use in the reinforcement of composite materials. The purposes for sizing include improving yarn cohesion, which is necessary for the weaving process, and increasing the adhesion between the fibres and the matrix. Nevertheless, during weaving, some fibrillation can occur, and that has detrimental effects on the weaving productivity and on the composite's properties. The purposes of this research were: (a) to determine whether abrasive wear between sliding fibres would modify the sizing and (b) to study the influence of sizing on the friction between fibres. The same type of carbon fibre was subjected to different desizing processes. The coefficient of friction between single fibres was obtained before and after desizing. The effects of sizing and sliding distance on frictional behaviour were investigated, and are related to the observed the wear of sizing layer. In fact, it increased with sliding distance and induced a decrease in the coefficient of friction. Moreover, an efficient desizing process induced a decrease of the coefficient of friction.

“…As illustrated in Figure 1(B), (C), two widely used categories of loading modes including compression–relaxation (CR) and compression–creep (CC) in the compaction process were reported [ 11, 15 ] and were performed here. Similarly, in the CR process, the fabric was initially compressed by the compression fixture with a constant speed of s = 1.0 mm/min until the stress reached to 0.25 MPa in the compression stage.…”

The strain response and influence of elevated temperature on the viscoelastic behavior of fabric in the compaction process cannot be described and predicted by current viscoelastic models. Here, a viscoelastic model, verified by compaction experiments, is originally proposed to depict the stress and strain responses in different stages of the compaction, especially considering the effects of added binder and elevated temperature. The model effectively captures that with the rising temperature, the interaction among fibers is enhanced due to the fiber volume expansion. Accordingly, the elastic modulus is enlarged in the compression stage. In the relaxation stage, the interaction suppresses the fiber realignment, leading to the reduction of stress relaxation. In the creep stage, the elevated temperature increases the deformation stiffness, indicating the strain is declined. In the relaxation stage, the adhesive effect of added binder facilitates the stress relaxation, and then the increasing stress relaxation promotes the increment of strain in the creep stage.

“…The compaction behavior of 3D woven fabrics has been a topic of recent researches. 18,[33][34][35] Several studies have considered mechanical properties, such as stiffness and strength of 3D woven fabrics from an experimental, analytical, and numerical standpoint, for example, Tan et al 36 and Tan et al 37 Cox and Dadkhah et al 38 showed that yarn nesting plays a significant role in failure under tensile loading, generating a significant drop in elastic modulus in both weft and warp directions. Leong et al 39 studied the effect of binder yarn on the tensile properties, and failure of woven composites.…”

In liquid composite molding processes, the compaction characterization of fibrous reinforcements plays a key role in determining the thickness, fiber volume content, and part shape. This study presents detailed experimental and modeling work to study the viscoelastic compaction response of three different types of 3D woven carbon fiber reinforcements, namely, orthogonal, angle interlock, and layer-to-layer, each having a different weave style and z-binder yarn pattern. For all reinforcements, single-step, multistep and cyclic compaction experiments were conducted. A nonlinear viscoelastic model is presented that accounts for large deformations and viscous effects, to capture the response of the material under various loading histories. Model verification is also presented to capture each response with separate sets of material parameters. Parametric studies are also performed to analyze the role of model parameters on the response of different types of loadings. X-ray computed tomography analysis showed significant permanent deformation of z-binder yarns through the thickness of the reinforcements. The comparison of modeling results with the experimental data show that the model is able to capture the stress decay after multiple compaction cycles, yet needs further investigations to predict complete cyclic hysteresis. However, model results agree reasonably well with the single and multistep compaction loading.
