Summary: This research aimed to develop laminated hybrid-composites using aramid woven fabric and curaua non-woven mat for military ballistic helmets. The study found that composites with one layer of curaua and 15 layers of aramid achieved the highest level of ballistic protection. The positioning of the curaua non-woven mat behind the aramid woven fabric, as well as the lower total number of layers, reduced the ballistic resistance of the hybrid composites.

Summary: This study investigates the use of a hybrid material consisting of synthetic aramid and natural lignocellulosic fiber for ballistic helmets. The replacement of aramid with curaua in the laminate composite materials results in a decrease in tensile strength and toughness, but improves rupture deformation. Reduction Maps analysis shows that the hybridization is advantageous when replacing nine or more aramid layers.

Summary: Driven by environmental concerns and sustainability issues, researchers have developed novel composite structures in various industries. This study focuses on designing and manufacturing aramid and basalt fiber reinforced polymer hybrid composites as an alternative to carbon fiber reinforced polymer (CFRP) composites. Different fiber ratios and stacking sequences were used to examine their effect on mechanical characteristics. Test results showed that tensile strength was dependent on fiber ratio and sequence, with CFRPs having the highest tensile strength. Impact test results revealed that basalt/aramid fiber hybrid composites had higher energy absorption capability compared to CFRPs. Additionally, increasing basalt fiber ratio increased water absorption capacity, while using aramid fiber in the upper layer decreased ignition loss and increased hardness values. Scanning electron microscopy analysis showed weaker fiber-matrix bonding in hybrid samples compared to CFRPs.

Summary: Separator is a crucial component in lithium-ion batteries (LIBs) as it significantly affects the electrochemical performance of the battery. However, the poor electrochemical performance of commercial LIB separators limits their use in electric vehicles and energy storage systems. This issue can be addressed by using different types of polymer separators and fabrication technologies. Electrospinning technology has gained attention for its ability to design new separator materials with high porosity, surface area, electrolyte uptake, and ionic conductivity. Among various polymeric separators, polyvinylidene fluoride (PVDF) and its copolymers are extensively used due to their desirable properties. This review discusses the impact of different PVDF-based electrospun separators on battery performance and highlights recent developments in improving electrochemical performance.

Summary: The search for sustainable plastics is driven by the environmental pollution issues associated with petrochemical-derived plastics. Bioplastics, such as poly(lactic acid) (PLA), are increasingly being used in packaging due to limited fuel resources. However, poor ductility and gas barrier characteristics limit the use of PLA as food packaging material. This study aims to overcome these limitations by fabricating PLA/polyethylenimine-modified mesoporous silica (PEI-MS) composites. The influence of PEI content in MS and wt % loadings of optimized PEI content in MS on the properties of PLA is investigated in detail. The results show that PEI-MS modification improves the thermal stability and mechanical properties of PLA.

Summary: In this research, the hybrid reinforcements of silica with either graphite or graphene oxide in natural rubber were studied. The addition of GO/SiO2 with a 3:1 ratio showed a synergistic reinforcement effect, significantly improving both strength and modulus while maintaining decent strain at break levels. The experimental data correlated well with the Guth Gold model, suggesting that filler/matrix interactions primarily govern the mechanical properties. The calometric response of the nanocomposites at the glass transition was analyzed, and the 3:1 GO/SiO2 composition showed the highest glass transition temperature and the most efficient filler intercalation.
