Woven composites have better integrity and anti-delamination properties than laminates, due to the interlaced yarns in the woven structures. However, these structural characteristics lead to a more complex failure mechanism, which brings great challenges to the damage evolution studies of woven composites. In this paper, the research status of damage evolution of woven composites is summarized and reviewed from the aspects of experimental techniques, damage evolution model and simulation. In terms of experimental techniques, the methods to characterize the damage evolution of woven composites are summarized emphatically, including the damage characterization based on strain, acoustic emission, infrared characteristics and computed tomography (CT). The application conditions, problems and challenges of these methods are reviewed briefly. In terms of damage evolution models and numerical simulations, the typical research methods for woven composites under quasi-static load, fatigue and impact load are summarized considering the loading characteristics. On the basis of the above summaries, the future research trends of damage evolution of woven composites are put forward, including the multi-means integrated characterization of damage mechanisms, damage related tests of macro and meso basic mechanical properties, macro and meso strength criterion and strength design, simulation models combining machine learning algorithm and finite element method or more, service performance studies based on digital twin and whole life cycle under complex circumstances, etc.

“…Fiber-reinforced composite materials are widely used in aerospace, transportation, military protection, and other fields due to their low density and high strength [ 1 , 2 , 3 ]. In the field of protection, fiber-reinforced composite materials can be directly prepared into armor for protection and can also be used as a back plate to form composite armor with a ceramic/metal panel [ 4 , 5 ].…”

Three-dimensional (3D) woven composites have attracted much attention in the lightweight research of protective armor due to their high specific strength and good impact resistance. However, there are still many gaps in terms of the performance and influencing factors of three-dimensional deep-angle-interlock (3DDAI) Kevlar/EP armor materials. Therefore, in order to prepare 3DDAI Kevlar/EP armor materials with excellent ballistic resistance and mechanical properties, this paper studies the bending performance of 3DDAI Kevlar/EP armor materials and the influence of the number of stacking layers, resin content, laying method, and weft density. Finally, we compare it with the traditional two-dimensional (2D) plain laminated Kevlar/EP armor material. The results showed that when the 3DDAI Kevlar/EP armor material was subjected to bending load, the upper and bottom layers of the material had a great influence on the initial stiffness and fracture strength of the material, respectively; when the material’s warp and weft density are quite different, the utilization rate of the yarn and the strength of the material are negatively affected; the fracture energy of the 3DDAI Kevlar/EP armor material prepared by the orthogonal laying method was about 20% higher than that of the 3DDAI Kevlar/EP armor material with the unidirectional layering method; and the bending performance of the 3DDAI Kevlar/EP armor material in the weft direction was better than that of the 2D plain laminated Kevlar/EP armor material, with the 3DDAI Kevlar/EP armor material having better delamination resistance. The research results will lay the foundation for structural optimization and engineering applications of such materials.

“…In line with the overarching goal of ICME to reduce the time and the cost in the discovery and development of novel CFRP composites structures, multi-scale computational models have been established and embraced in our previous work and those of other researchers [12][13][14][15][16][17][18][19][20][21][22][23][24]. A majority of those models deliver the concerned information embedded in equations and parameters from lower-scale simulations to higher-scale, which is termed as the bottom-up hierarchical approach [17].…”

A bottom-up multi-scale modeling approach is used to develop an Integrated Computational Materials Engineering (ICME) framework for carbon fiber reinforced polymer (CFRP) composites, which has the potential to reduce development to deployment lead time for structural applications in lightweight vehicles. In this work, we develop and integrate computational models comprising of four size scales to fully describe and characterize three types of CFRP composites. In detail, the properties of the interphase region are determined by an analytical gradient model and molecular dynamics analysis at the nano-scale, which is then incorporated into micro-scale unidirectional (UD) representative volume element (RVE) models to characterize the failure strengths and envelopes of UD CFRP composites. Then, the results are leveraged to propose an elasto-plastic-damage constitutive law for UD composites to study the fiber tows of woven composites as well as the chips of sheet molding compound (SMC) composites. Subsequently, the failure mechanisms and failure strengths of woven and SMC composites are predicted by the meso-scale RVE models. Finally, building upon the models and results from lower scales, we show that a homogenized macro-scale model can capture the mechanical performance of a hat-sectionshaped part under four-point bending. Along with the model integration, we will also demonstrate that the computational results are in good agreement with experiments conducted at different scales. The present study illustrates the potential and significance of integrated multi-scale computational modeling tools that can virtually evaluate the performance of CFRP composites and provide design guidance for CFRP composites used in structural applications.
