Carbon Fiber Composite

This work presents numerical simulation methods to model the mechanical behavior of the multifunctional energy storage composites (MESCs), which consist of a stack of multiple thin battery layers reinforced with through-the-hole polymer rivets and embedded inside carbon fiber composite laminates. MESC has been demonstrated through earlier experiments on its exceptional behavior as a structural element as well as a battery. However, the inherent complex infrastructure of the MESC design has created significant challenges in simulation and modeling. A novel homogenization technique was adopted to characterize the multi-layer properties of battery material using physics-based constitutive equations combined with nonlinear deformation theories to handle the interface between the battery layers. Second, mechanical damage and failure modes among battery materials, polymer reinforcements, and carbon fiber-polymer interfaces were characterized through appropriate models and experiments. The model of MESCs has been implemented in a commercial finite element code in ABAQUS. A comparison of structural response and failure modes from numerical simulations and experimental tests are presented. The results of the study showed that the predictions of elastic and damage responses of MESCs at various loading conditions agreed well with the experimental data. © 2021

Different Levels

In this study, carbon fibers (CF) were braided with polypropylene (PP) fibers on a 16-spindle braid machine, forming the PP/ CF composite braids. The composite braids with different levels of strength could be obtained by changing the speed of the yarn turntable and volume gauze. The composite braids with optimum tensile strength then received the thermal treatment, which melted the PP fibers to wrap the CF more tightly, stabilizing the structure of the composite braids. According to CNS 11623 (Tensile Properties of Geogrids by the Single), the composite braids were thermal-treated at 170 °C, 180 °C and 190 °C for1 min, 2 min and 3 min, determing the influence of thermal temperature and duration on the tensile strength of PP/ CF composite braids.
