Summary: Single-layered, double-layered, and three-layered woven lattice sandwich-ply (WLS) composites were designed and manufactured in this research. Bending experiments were conducted on clamped and simply-supported WLS panels to investigate the effects of multi-layered construction and boundary constraints on flexural behaviors. The results revealed typical damage modes for panels with four constrained ends including core fracture, face shear fracture, and bending fracture, while panels with two constrained ends showed core shear, compression fracture, and face fracture. The study demonstrated that multi-layered construction significantly improved strength, stiffness, and energy absorption, and the influence of boundary constraint on deformation characteristics decreased with increasing core shear stiffness.

Summary: Raman spectroscopy is a crucial technique for analyzing carbon-based materials, providing unique insights into their microstructure. It allows for characterization of aspects such as orientation, layers, defects, and doping, enabling standardization and quality control. The application of Raman spectroscopy in studying graphene has aided in the analysis of carbon nanotubes and fibers. The technique can also be used to track deformation in carbon-based materials and study interfacial micromechanics in composites.

Summary: This research investigates the behavior of bolted joints in composite laminates that combine thin-plies and conventional thick-plies. The study found that inserting the thin-plies into the laminate can improve bearing strength. The analysis of fractures showed that damage mostly occurred in the normal plies rather than the thin-plies. For samples with a block of thin-plies in the middle, all delaminations were forced to the surface layers with a larger size.

Summary: Hybrid composites made of bio-based thin-ply carbon fiber prepreg and flame-retardant mats were studied for their fire protection performance and mechanical properties. The addition of flame-retardant mats improved the fire protection properties by reducing ignition time and heat release rate, but led to a reduction in tensile and bending strength of the laminates.

Summary: Textile-reinforced carbon/carbon composites exhibit excellent thermophysical properties and are commonly used for thermal safety. This study developed multiscale representative volume element (RVE) models to investigate the coefficient of thermal expansion (CTE) of spread tow woven pierced carbon/carbon composites (STWPs) at high temperature. The accuracy and effectiveness of the models were confirmed through comparisons with experimental findings, demonstrating good agreement. Furthermore, the effects of pore positions, configurations, and areal density of the ST woven fabric on the CTE of STWPs were analyzed.

Summary: Three-dimensional (3D) tow reinforced hybrid molding combines continuous fiber composite tow with injection overmolding to improve mechanical performance of molded components. However, the conventional modeling processes cannot accurately capture the tensile performance due to the waviness of the fibers when wrapped around load introduction points. The Hsaio and Daniel model was used to predict the elastic properties of the wavy fiber composite and showed that neglecting or modeling the waviness leads to significant differences in the predicted stiffness and strength.

Summary: Textile reinforced composites, specifically spread tow woven pierced composites (STWPs), are commonly used in thermal protection engineering due to their exceptional mechanical and physical properties. This study focused on analyzing the thermal conductivities of STWPs and proposed numerical models to accurately predict their thermal performances. The results showed that the fiber volume fraction, porosity, and interphase thermal conductance significantly affect the thermal conductivities of STWPs.

Summary: Two types of hybrid composite specimens with glass/carbon fiber-epoxy interlayer were studied, one with continuous carbon layer and the other with discontinuous carbon layer. The tensile and interlaminar properties of the hybrid composites were tested at different temperatures and under different conditions to investigate their temperature dependency and moisture sensitivity. The results showed that the tensile response of the continuous specimens was not influenced by temperature, while the discontinuous specimens delaminated at the glass/carbon interface. Increasing the test temperature led to a significant decrease in the mode II fracture toughness of the glass/carbon hybrid composites. The presence of moisture changed the behavior of both types of hybrid composites, causing unstable delamination and glass fiber failure due to the decreased strength of the S-glass/epoxy layers.

Summary: The study explored the use of jute fibers as substitutes for carbon fibers in composite materials, demonstrating that carbon/jute hybrids exhibit superior dynamic mechanical properties. Placing carbon fibers in the inner layers and jute fibers in the outer layers resulted in reduced performance compared to hybrids with jute in the inner layers. Hybridization with jute fibers increased the damping factor at higher temperatures.

Summary: This research investigates the damping response of hollow tubular structures using a novel acrylic liquid thermoplastic Elium resin and different carbon fiber reinforcement materials. The results show that the use of the new materials increases the damping of the structure, with carbon fiber reinforcement having a greater effect on damping enhancement. Additionally, the thickness of the tube has a positive effect on damping, while an increase in fiber volume fraction has a negative effect.

Summary: This research focuses on the optimization of ultrasonic welding of carbon/epoxy composite and carbon/ Elium(R) composite using a PMMA coupling interlayer. The results show that the welding strength can be significantly improved by creating a PMMA coupling layer on the epoxy composite adherend. The welding time can be reduced to 2s compared to the 10 min required for adhesive bonding. The investigation also reveals the characteristics of the fracture surface for the configuration with maximum lap shear strength. This research presents a way to join Elium(R) with epoxy composites and has potential applications in sporting goods and consumer products.

Summary: The study aims to investigate the impact of green logistics on the adoption of Circular Economy (CE) in the era of Industry 4.0 (I4.0). By implementing green initiatives, the logistics sector shows its strong concern for environmental issues and promotes sustainable logistics and circular practices to address critical issues such as waste generation, resource scarcity, renewable resource use, and climate change. The study examines the relationships between green logistics practices, I4.0 technologies, and CE adoption while also considering the moderating effects of institutional pressure and supply chain flexibility. The findings suggest that firms can enhance CE adoption driven by I4.0 technologies with green logistics practices as a mediator, and the moderating effect of supply chain flexibility is significant while the moderating effect of institutional pressure is insignificant. The study provides valuable insights for managers and contributes to the theoretical understanding of green logistics and CE adoption.

Summary: Social media has become a major source of information for young users, but it has a severe impact on mental state due to information overload, which is still a concern for researchers. The addiction of Generation Z users to mobile phones/gadgets is increasing with the rise of social media, leading to a complete transformation in their behavioral outcomes. Behavioral issues such as stress, fatigue, fear of missing out, phubbing, and anxiety are on the rise, but the relationship between these issues and information overload has not been sufficiently examined. The study finds that social media platforms need to understand users' compulsive usage, which results in fatigue and anxiety, and government information support plays a positive role in reducing fatigue and anxiety.
