“…This is made feasible by the use of a complex HYTT preform made partly of near net‐shaped 3D fabrics whose fibers are adapted to the respective loading paths (e.g., those to which the wheelhouses are subjected) . Furthermore, the integration of near net‐shaped shell stringer fabrics ensures the fulfilment of structural criteria while also minimizing weight as described in Mountasir et al Extensive research into the dimensioning of HYTT structures was therefore carried out, thus facilitating the use of novel damage models for HYTT composites to describe complex, non‐linear structural behavior under static and dynamic loading . Those models also made it possible to validate the structural resistance of components such as the bodywork and the adaptive leaf spring.…”

Future mobility applications are characterized by a high level of resource efficiency due to the application of novel lightweight materials and function-integrating, multi-material design concepts. Textile thermoplastic composites in particular pave the way for lightweight components characterized by highly specific mechanical properties and efficient production processes. This essay presents the strategy pursued by the Collaborative Research Centre SFB 639 "Textile-reinforced composite components for function-integrating multi-material design in complex lightweight applications", a concept for the holistic analysis of complex process chains for hybrid yarn textile thermoplastic (HYTT) composites and the idea behind the innovative FiF electric mobility technology demonstrator vehicle.

“…Besides, the weaving process of 3D woven composites allows for various types of yarns and different woven parameters (such as spacing between yarns, number of layers and so on), which enriches the design flexibility for satisfying specific performance requirements [6]. Furthermore, the net-shape preforms of 3D woven composite structures also could be produced to reduce overall manufacturing cost [7,8].…”

This paper investigates the tensile properties of 3D orthogonal woven carbon fiber composites with tilted binder by experiment and simulation. The tensile failure strain and fracture mode of this composite show distinguished discrepancy with idealized 3D orthogonal woven composites experimentally. In order to explain this specific failure mechanism, a unit cell finite element model incorporated with damage models of constituents is established to reproduce the damage initiation and propagation of 3D orthogonal woven composites with tilted binder during tensile test. A three-dimensional failure criterion based on Hashin's criterion and Pinho's criterion is utilized to describe the progressive damage of yarns, while the non-linear behavior of the matrix is predicted by Drucker-Prager yield criterion. Besides, a traction-separation law is applied to predict the damage of yarn-matrix interface. The proposed unit cell model is correlated and validated by global stress–strain curves, DIC full-field strain distributions and modulus history curve. The damage evolution process of 3D orthogonal woven carbon fiber composites with tilted binder, including fiber tow failure, matrix cracking, and interfacial debonding, is recorded and investigated by the modulus history curve from simulation.

“…At present, fiber reinforced polymer composites (FRP) have attracted tremendous interest in terms of their excellence mechanical performance, corrosion resistance, design freedom as well as easy‐going process, which are widely applied in various industries such as automotive, electronics & electrics, wind power, and aviation . Behaving as a bridge involving the stress transfer, the interface makes great difference in the mechanical performance of FRP composite especially when the fiber loading is high in long fiber reinforced technology .…”

The interfacial crystallization at glass fiber/PP interface in the presence of multiwalled cabon nanotubes (MWCNTs) and organic nucleating agents (NAs) along fiber surface was investigated in this study. MWCNTs and NAs formed a uniform coating layer on glass fiber surface via dipping in well‐dispersed MWCNTs and NAs aqueous dispersions. Transcrystalline (TC) structure formed by the strong nucleating ability of MWCNTs/NAs coated glass fiber surface. There existed a detectable difference in TC structure induced by coated glass fiber with different surface components. We found that a more sufficient and higher density transcrystalline (TC) structure can be constructed by introducing MWCNTs in combination with sodium benzoate (SB) or TMB‐5 onto fiber surface. Interfacial adhesion was evaluated by interfacial shear strength (IFSS) and morphologies at interfacial region after microdroplet test. The result shows that the MWCNTs/NAs coated glass fiber relates to better interfacial adhesion indicating that enhanced interfacial adhesion derives from the sufficient and high density TC structure induced by MWCNTs and NAs. Our current work provides an effective pathway to construct TC structure and further enhances interfacial adhesion of glass fiber/polypropylene composites. POLYM.
