“…Typically, carbon fiber structural composite materials are manufactured using layers of a woven fabric containing a few thousand reinforcing fibers stacked in different angular orientations (Barile and Casavola, 2019). In our case, randomly oriented woven non-woven PLA electrospun fiber mats are used in a three-layer stack of Nu/ePLA/Nu or Su/ePLA/Su.…”

Taking advance of the fiber-reinforced polymer process, commonly used in the fabrication of polymer composites, in this work we used electrospun microfibers to reinforce self-healing ionomeric polymers producing sandwich-type composites. In particular, three-layer stack with poly(lactic acid), PLA, electrospun fibers in between two layers of commercial smart polymers has been obtained based on poly(ethylene-co-methacrylic acid) (EMAA) copolymers, well-know with the tradename of Nucrel ® and Surlyn ® , both of them manufactured by Dupont TM Company. Surlyn ® is the corresponding ionomer of Nucrel ® in which the MAA groups are partially neutralized with sodium ions. In general, one of the main problems of thermoplastic composites, that provoke a lower impregnation of the fiber, is the high viscosity of the molten matrix. Therefore, in this work, we used electrospun microfibers in order to solve impregnation problem, thus considering that electrospinning process is an accessible, versatile and low-cost technique for fibers formation in the range of micron and nanometers. In order to create the sandwich-type structure, firstly, the optimization of the processing window has achieved in order to maintain the randomly oriented fiber structure on the final composites. In particular, the creation of sandwich-type structure with Surlyn ® reinforced with woven non-woven electrospun fibers based on PLA with enhanced mechanical as well as hardness and wear resistance can be used for future active packaging solutions.

The present work describes the mechanical characterization combined with the thermal degradation kinetics of Carbon Fiber Reinforced Polymers (CFRP). The thermal degradation kinetics of CFRP have never been studied in the past. In that regard, the present work focuses on studying the thermal degradation kinetics of CFRP tested mechanically at different environmental conditions. Tensile tests were performed on the specimens with different lay-ups at room temperature, elevated temperature (71 °C), and cryogenic conditions (−54 °C), and the same specimens were used for thermal degradation kinetic studies. Mechanical tests show different responses respect to the different environmental conditions and different fibers orientation. On the other hand, the thermogravimetric results, mass loss, and derivative mass loss, show no significant difference in the degradation of CFRP tested at different temperatures. However, the thermal degradation kinetics shows more insight into the degradation pattern of the materials. The activation energy of degradation shows that the degradation of materials subjected to elevated conditions increases rapidly in the later stages of degradation, suggesting the formation of high char yield. The varying activation energy has been related to different degradation mechanisms. Lastly, the morphology of the materials was studied under SEM to understand the structural change in the material after tested in different weather conditions.

“…Compared with traditional metals, carbon fiber and other composite materials have the characteristics of light weight, high strength, and corrosion resistance. [5][6][7] They are not only applied in automobile covering parts, but also gradually applied as structural parts in automobile energy absorbing and buffering components. [8][9] However, the structure of composite materials is often subject to brittle failure, mainly manifested as fiber fracture, stratification and debonding, [10,11] which cannot be directly applied to replace metal structures.…”

To take into account the lightweight and collision safety of the energy absorber, metal-composite hybrid thin-walled tubes have been widely studied, which combine the low-cost metal and high-strength composites. Therefore, the deformation mechanism and the characteristics of the carbon fiber reinforced plastic wound thin-walled aluminum tube (Al-CFRP) were investigated under radial compression condition. Firstly, aluminum tubes, CFRP tubes, and four winding angles of Al-CFRP hybrid tubes (27 , 45 , 74 , 90) are experimentally analyzed. The contrastive results show that the stability and energy absorption of the Al-CFRP hybrid tube are improved and the winding angle is one of the important factors that affects the radial compression performance of the hybrid tube. And then based on the hybrid model, some theoretical relations are derived to forecast the initial collapse force and energy absorption quickly. The theoretical analysis shows that the radial force on the hybrid tube during the compression is also dependent on the thickness ratio of Al-CFRP layers complicatedly except the winding angle. Therefore, the effects of the winding angle (0-90) and thickness ratio of Al-CFRP layers (0.25-3.5) on the radial compression performance are investigated. The theoretical predication results show that the hybrid with the winding angle of 90 and thickness ratio of Al-CFRP layers of 0.25 performs over six times of the initial collapse force than the Al tube. Finally, the simulated model based on ANSYS and LS-DYNA is established to explain the reason for the better radial compression performance (A5C10S90) and the deformation mechanism of the hybrid tube, through the stress analysis of inner Al tube, inner CFRP layer, and outer CFRP layer, respectively. It is found that the Al-CFRP hybrid tube (especially 90) under radial compression shows better bearing capacity which represents the higher initial collapse force, total energy absorption and specific energy absorption, due to the supporting of the inner Al tube and the protection of the outer CFRP tube.
