Role of weave design on the mechanical properties of 3D woven fabrics as reinforcements for structural composites

Self Cite

In advanced engineering applications, machining of composite material is a must to perform necessary assembly operations. This work deals with the investigation of fabrication potential of Glass/epoxy composites reinforced with different textile structures in the form of E-glass based chopped fiber, unidirectional (UD) tow, bidirectional (2D) plain woven, four different 3D woven orthogonal solid structures with varying binder percentage and one 3D woven angle interlock structure. The Influence of reinforcement architecture on tensile strength, drilling damage, bearing response, specific energy absorption (bending), and spring stiffness of composites structure was investigated. Damage analysis due to drilling was primarily assessed in terms of delamination whereas bearing strength, bearing strain and common bearing failure were examined from the bearing strength test. Different bearing failure was observed for different composite structures; UD composite was noticed with complete shear out failure while chopped failed due to tearing and 2D structure reinforced composite predominantly failed due to tearing and delamination failure. 3D orthogonal composite failed due to tearing in the warp direction and shear out in weft direction whereas 3D interlock failed due to tearing in both warp and weft direction. 3D orthogonal based composite structure exhibited the highest specific energy absorption (SEA) along with improved spring stiffness and therefor it could be a potential material for automotive leaf spring application.

“…A computer program was developed to predict the various geometrical parameters for the unit cell as shown in Figure 13.C# was used to develop the interface to view the results for the Mathematical Code written in Python. The equations (1) to (12) stated above have been integrated into the algorithm and then implemented into the Python console. This algorithm is responsible for computation.…”

Prediction of internal geometry and tensile behavior of 3D woven solid structures by mathematical coding

The internal geometry of composite material is one of the most important factors that influence its performance and service life. A new approach is proposed for the prediction of internal geometry and tensile behavior of the 3 D (three dimensional) woven fabrics by creating the unit cell using mathematical coding. In many technical applications, textile materials are subjected to rates of loading or straining that may be much greater in magnitude than the regular household applications of these materials. The main aim of this study is to provide a generalized method for all the structures. By mathematical coding, unit cells of 3 D woven orthogonal, warp interlock and angle interlock structures have been created. The study then focuses on developing code to analyze the geometrical parameters of the fabric like fabric thickness, areal density, and fiber volume fraction. Then, the tensile behavior of the coded 3 D structures is studied in Ansys platform and the results are compared with experimental values for authentication of geometrical parameters as well as for tensile behavior. The results show that the mathematical coding approach is a more efficient modeling technique with an acceptable error percentage.

A review on the mechanical performance of three-dimensional warp interlock woven fabrics as reinforcement in composites

et al. 2020

In recent years, the research interest on three-dimensional warp interlock woven fabrics (3DWIFs) as reinforcement in composites is warranted and obtained popularity due to their advantages over two-dimensional laminated fabrics. The current literature tends to address the aspects of mechanical properties of 3DWIFs by experimental and numerical approaches. This review aims at providing an overview and comprehensive understanding of dry 3DWIFs. The filaments/yarns used, the common structures, and categories of 3DWIFs are reviewed. Recent characterizations of the mechanical performance of dry 3DWIFs are discussed. Theoretical and numerical models for predicting the mechanical properties of dry 3DWIFs are also delineated. The critical review can provide valuable ideas and guidance for future studies.
