“…Based on the architecture of reinforcement, the influence on the mechanical properties were studied. 3D crimps fabrics [46], shallow-straight and shallow-bend woven fabrics [47], fabrics with or without binder yarns [14], were proposed to study the effects on the mechanical properties of corresponding composites. Further on, novel 3D woven fabrics, such as bidirectional angle interlock fabrics [48] and fabrics based on group P 4mm [49], were developed to improvement the performance and meet application requirement.…”

3D woven fiber/epoxy composites as structural components have attracted great attention in the industrial and civil fields due to high resistance to debonding or delamination. Structural components are often subjected to the conditions of cyclic loading, which detrimentally affect the service-life and damage tolerance. In this research, the fatigue properties of 3D woven fiber/epoxy structural composites were discussed, where 3D woven fabrics were embedded in epoxy matrix to enhance their mechanical properties. 3D woven fabrics were classified by the geometrical structures of repeat vertical and inclined units. Based on the testing method, the fatigue properties of corresponding composites have been reviewed. The influence of the internal and external parameters on the fatigue properties were investigated by using various observation methods, and the failure modes were also analyzed. The theorical prediction models were reviewed according to testing method, and future trends and challenges were discussed. The critical review can provide valuable ideas and guidance for future fatigue studies in 3D woven composites.

“…To simplify the calculation and simulation process, as shown in Figure 2, the cross-sectional shapes of these three groups fiber tows are supposed to be rectangle. 28 Fiber volume fraction refers to the volume of reinforcing fiber tows per unit volume of composites. The fiber volume of the orthogonal unit can be calculated by formula (2)…”

Three-dimensional textile fabrics are used as the reinforcing phase of the textile structural composites, and their geometry affect the physical and mechanical properties of composites. Based on the curvature and directions of the fiber tows in three-dimensional textile fabrics, four representative geometric units are proposed, namely, the orthogonal geometric unit, the curved geometric unit, the skew geometric unit, and the uniform distribution unit, respectively. Other units are the combinations or derivations of these representative geometric units. The relationship and performance characteristics of these representative geometric units are discussed in section “The relationship of RGUs.” The structural features of three-dimensional textile fabrics are illustrated on the mesoscopic scale, and the models are established to predict the geometric properties. The concepts of fabrics with stable structure, flexible structure, elastoplastic structure, and uniform structure are proposed. The fiber volume fractions and elastic characteristics of different structural fabrics are discussed. The classification of three-dimensional textile fabrics is conducive to investigate the relationship between geometry and property, forming a technical system and providing a theoretical basis for the selection of three-dimensional structural textile composites with different performance.

“…The yarn topology in the 3D braided preform decides yarn orientation and fibre volume fraction of the preform [3]. The yarn topology changes with braiding method adopted such as surface-core braiding [14], multilayer braiding [10], multilayer interlock braiding [15], and orthogonal braiding [16]. The yarn topology also changes with the interlacement pattern, i.e.…”

The present research reports the geometric model of four-directional 3D (4D3D) braided preform developed on four-step 3D braiding machine which consists of even and an equal number of yarn carriers in the rows and columns, respectively, on machine bed. The yarn path within the unit cell of the preform was analyzed to establish the correlation between surface braiding angle and interior braiding angle. A single unit cell model approach was used to predict the fibre volume fraction of the preform. It has been observed that the number of yarn carriers in the rows and columns is a critical parameter to decide the geometry of 4D3D braided preform. The fibre volume fraction predicted by the present model was compared with the three-unit cell model, multi-unit cell model and experimental results. A good agreement was observed between model computed results and experimental results.
