Summary: A theoretical energy-based model was developed to capture the ballistic response of sandwich structures made of composite material peels and a crushable foam core. The model was based on wave propagation theory and divided into six stages with corresponding energy-absorption mechanisms, showing the general trends in terms of their relative importance at velocities below, near and above the ballistic limit. The model was validated against experimental results, demonstrating good agreement in terms of impact-residual velocity curve.

Summary: This paper investigates the preparation of high-impact polyurethane composite material with excellent mechanical strength and good adsorbability by compounding different size of polyester and nylon nonwovens with melamine-bentonite composite PU foam. The mechanical properties and cellular structure of PU foam are influenced by the composition of the two different fabrics. The addition of fabric improves the mechanical property of composites and enhances the adsorption of Pb2+ effectively.

Summary: In the past two decades, there have been significant developments in aircraft crashworthiness, thanks to modern computing systems and commercial finite element codes. However, the design of the fuselage section with an onboard auxiliary fuel tank has presented challenges in installing an efficient energy absorber. To address this issue, a PVC composite foam and aluminum plate were introduced beneath the fuel tank to enhance the crashworthiness metrics of the fuselage. Experimental results showed that reinforcing the foam and plate improves the kinetic energy absorption by 3.54% and contributes 20% to the total internal energy dissipation. Numerical outcomes also indicated a 41% reduction in maximum stress on the cabin floor surface and a decrease in maximum peak acceleration responses of the cabin floor at different locations by 6% to 36%.

Summary: A novel all-composite sandwich panel with channel core was proposed to enhance compressive strength and energy absorption characteristics. Experimental and numerical analysis results showed that the proposed structure exhibited better compressive strength and specific energy absorption compared to the traditional corrugated core sandwich panel. Further optimization of the structural efficiency through foam filling significantly increased the compressive strength and energy absorption.

Summary: Due to the rapid growth of electronic equipment technology, efficient electromagnetic shielding materials are needed for equipment and human protection. In this study, Fe3O4@Polyvinyl alcohol (Fe3O4@PVA) and graphene oxide@silver (GO@Ag) were added to the polyurethane (PU) matrix to construct composite foam with improved electromagnetic shielding effectiveness (EMI SE) and mechanical properties. The results demonstrated that the absorption mechanism played a primary role in the electromagnetic shielding, making the constructed materials promising for applications in aerospace, portable electronic devices, and lightweight wearable devices.

Summary: An amorphous sheet-raspberry sandwich-like ZnCo2S4@MnCo2S4/CP composite material was synthesized as a counter electrode for dye-sensitized solar cells (DSSCs) using a three-step hydrothermal method. The amorphous composites exhibited lower charge transfer resistance, improved fill factor, and short-circuit current density, attributed to the unique structure, smooth ion transport interface, and dual catalytic performance of the Zn, Co, and Mn composites. When used as the counter electrode, the composite material achieved a high photoelectric conversion efficiency of 11.68%. This study provides a design idea for amorphous materials in terms of catalytic performance and an alternative to Pt electrodes.

Summary: This paper investigates the crushing performance of a hybrid system consisting of carbon fibre-reinforced plastic (CFRP), polyurethane (PU) foam, and aluminium alloy (Al). The study finds that increasing the diameter or wall thickness of the outer CFRP tube can enhance the energy absorption of the composite structure. Additionally, the ply orientation also affects the energy absorption characteristics.

Summary: Fiber reinforced plastics filled with polyurethane foam are widely used as energy absorbers for safety enhancement. The study found that using PU foam inside CFRP composite tubes increases peak load and energy absorption, while internal CFRP reinforcements do not significantly improve energy absorption but do improve peak load.

Summary: This article introduces a novel strategy of using sustainable renewable polymer foam as a lightweight porous skeleton for microwave absorption. The researchers prepared renewable microwave-absorbing foams by using a specific type of polyurethane foam and Fe3O4 nanoparticles. Through systematic characterization and analysis, it was found that the foam displayed a porous hierarchical structure and was multi-interfacial, which contributed to its excellent microwave absorption performance. The lightweight nature and broadband absorption of the foam make it a prospective material in the field of lightweight stealth materials.
