International audienceBraided composites tubes have been reported to have a great potential in crash energy absorption applications. However, previous works were limited to thermoset braided composite tubes. In this study, we are interest in the crash energy absorption performance of 2.5D braided thermoplastic composite tubes. The sensitivity to materials, fiber orientation and geometry was investigated. Three crushing modes have observed. The splaying and progressive folding were reported for glass/polypropylene tubes and fragmentation mode was observed carbon/polyamide tubes. The last mode has the highest specific energy absorption of 61 kJ/kg. The progressive folding mode has higher specific energy absorption (36 kJ/kg) than the splaying mode. Moreover, the specific energy absorption increases with increasing braiding angle and decreasing length-to-diameter ratio, for glass/polypropylene tubes. On the opposite, the specific energy absorption deceases with braiding angle for carbon/polyamide tubes

Recent work on multifunctional materials has demonstrated that high-strength composites could be integrated with active Li-ion battery material to create high strength and high energy density storage structures that could meet the transportation requirements on mobility and energy storage density. However, the performance and the design of the multifunctional materials require fundamental understanding of the mechanical behavior of the integrated Multifunctional Energy Storage (MES) Composites systems under various loading conditions. Characterization of this new class of multifunctional materials would become very challenging without an adequate simulation model to guide the tests and validate the results. Therefore, this work presents the mechanical simulation and design of the MES Composites system that consists of multiple thin battery layers, polymer reinforcements, and carbon fiber composites, which results significant challenges in simulation and modeling. To tackle these issues, homogenization techniques were adopted to characterize the multi-layer properties of battery material with physics-based constitutive equations combined with non-linear deformation theories to handle the interface between the battery layers. Second, both mechanical and electrical damage and failure modes among battery materials, polymer reinforcements and carbon fiberpolymer interfaces were characterized through appropriate models and experiments. The model of MES Composite has been implemented in a commercial finite element code. A comparison of structural response and failure modes from numerical simulations and experimental tests will be presented in the paper. The simulated strain distribution and its application to Structural Health Monitoring (SHM) on MES Composites will also be discussed. The results of the study showed that the predictions of elastic and damage responses of MES Composites at various loading condition agreed with the test data. With appropriate material parameters determined from experiments, this multi-physics model can be used as a necessary tool to characterize a failure envelop that governs the design of MES Composites under specified electrical and mechanical loads.

“…Beard successfully simulated the quasi-static crushing of plug-initiated triaxially braided circular and square tubes using a micromechanical model incorporated into ABAQUS/Implicit [8][9][10]. The model was later incorporated into ABAQUS/Explicit and used to model dynamic crushing processes by Flesher [11][12][13]. Castejon [14] made effort to model the crush behavior of chamfered braided composite tubes.…”

Braided composite tubular structures are of interest as viable energy absorbing components to improve vehicle passive safety. Unfortunately, there are many difficulties in predicting the crash response of braided composite tubes. In this study, a progressive failure model for braided composite materials, which had been implemented as a user material model in ABAQUS/Explicit, was used to simulate the axial crash response of braided composite tubes. It was shown that the model adequately captured the failure characteristics (such as matrix cracking, fiber fracturing and delamination) and energy absorption of braided composite tubes under axial compression. In addition, the simulation results show that braided composites have higher energy absorption performance compared to traditional metals.
