“…The flattening ratio then represents the weight of the tow flattening phenomena in the total force required to compact the fabric. Results of [8] were used to calculate the flattening ratio for fabrics B and C. However, there was no existing characterization for fabric A, so the exact same experimental method was used to calculate the flattening ratio. It was possible to directly apply the model of Vernet and Trochu for this fabric as it is very close to those studied (same fibers, sizing, manufacturer, number of fibers per tow, pattern and number of interlock layers), with the same values of l t and F Ã g (see Eqs.…”

“…Therefore, a physical approach was used in this study by defining the flattening ratio. It is calculated for each fabric based on the model of Vernet and Trochu [8], described in the following equations. This model allows calculating the contribution of tow flattening force ðF flattening Þ and tow bending force ðF bending Þ in the total compaction force of the fabric ðF tot Þ engaged at peak in a relaxation test at a V f of 58%.…”

“…For the multilayer case, the sliding between layers (nesting) appeared as the third component dominating compaction behavior [14,17]. This approach of compaction analysis was extended to 3D interlock fabrics by Vernet and Trochu [8]. They considered that compaction behavior is mainly governed by tow flattening and bending and developed a model to estimate the total compaction force of a fabric depending on weaving parameters.…”

“…Based on this principle, he developed an elastic model to predict the transverse compaction force of the bundle. This model has been improved by other authors to model the compaction of woven fabrics [8,14,15]. For the single layer case, authors identified tow flattening and tow bending as the components of the total compaction force [15,16].…”

“…Consequently, warp tows present a certain out-ofplane waviness that is called through-thickness crimp. The compaction behavior of 3D woven fabrics has been recently studied [6][7][8] but not as widely as for 2D fabrics.…”

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 reinforced fibers of three-dimensional (3D) composites are interwoven in space and have better inter-laminar properties than two-dimensional (2D) laminates, and have great application prospects in high-tech fields.Flexible-oriented 3D woven technology is an emerging technology for weaving 3D composite preforms, especially suitable for manufacturing large-thickness and complex preform architectures, and the compaction behavior of preforms has an important influence on its performance. In this paper, using this technology, different types of 3D preforms were woven and subjected to systematic compaction experiments, to explore the effects of different fiber hybrid modes and process parameters on the compaction behavior. It is found that, increasing the number of cycles, wetting and sizing the fibers are all beneficial to improve the compaction ability, but reduce the stress relaxation and recovery ratios. The stress relaxation of the hybrid fiber preform is mainly affected by the carbon fiber. Reducing the dispersion of different fiber bundles is beneficial to decrease the recovery ratio. The research results provide experimental and theoretical reference for the rapid and efficient weaving of hybrid fiber composite preforms in the future.
