The eco‐friendly characteristics of green composites not only make them economically and technically viable but also contribute to the reduction of pollution. Green composites are developed by combining degradable fibers (primarily cellulosic materials) with natural resins. A disadvantage of green composites is their lower mechanical strength. To address this issue, 3D woven reinforcement along with fillers can be used to enhance the mechanical properties of green composites. In the current study, three different types of novel 3D woven hybrid structures, that is, hybrid through the thickness (HB‐1 (TT), novel woven layer‐to‐layer structure (HB‐2 (LL)), and layer‐to‐layer structure with double warp yarn (HB‐3 (LL)) were developed. Composites were fabricated using the compression molding technique. Three different concentrations (2%, 5%, and 8%) of nano clay (nanoparticles) were used as fillers and mixed in the green epoxy resin. Pendulum (Charpy) and drop weight impact tests of the composites were performed. The results showed that by the addition of nano particles the impact properties were increased. Nanoparticles showed a significant effect on impact strength. Charpy impact test results showed that the HB‐3 (LL) composite sample with 8% nanofillers showed the highest impact performance, while the HB‐1 (TT) composite sample with 8% nanofillers showed the highest impact performance during the drop weight impact test. By comparing the impact strength of the present work with that of similar research previously published, it is evident that our study achieved a remarkable improvement of 19.17%. This increase is due to the novel structures and nano fillers in the composite.Highlights Eco‐friendly green composites: economically feasible, minimizes pollution. Adding 3D woven structures to green composites improves their mechanical properties. Composite materials with nano clay fillers have increased impact resistance. The highest impact performance is shown by HB‐3 (LL) composites with 8% nanofillers.

Numerical analysis based on micromechanics is an effective method to study the mechanical properties of three-dimensional (3D) braided composites, in which the establishment of micromechanics model is the basis of mechanical analysis. The direction cosine of fiber yarns and the characterization of geometric parameters of microstructure are two key issues in the modeling of microstructure. Focusing on these two key issues, the three-cell model of 3D four-directional braided composites are studied to comprehensively analyze various spatial directions of fiber yarns in the 45°division and horizontal division of unit cell, so as to obtain the detailed fiber yarn direction cosine. Aiming at the cross sections of three types of fiber yarns, the complex relationship between the braiding process parameters and the geometric parameters of the unit cell is analyzed and deduced. The unitcell structure is quantitatively characterized by using the braiding process parameters as the initial parameters, and the calculation methods of the volume fraction of fiber yarns and yarn filling coefficient are obtained. Finally, the predicted elastic constants by stiffness-volume averaging method are compared with experimental results, demonstrating the analysis results of fiber yarns directions. This paper can provide a theoretical reference for the microstructure modeling of 3D multi-directional braided composites, and has certain practical value in engineering.
