Summary: The computational framework utilizes novel differential effective medium approximation and mean-field homogenization to design high-performance filler-laden polymer thermal interface materials. The design strategy allows for handling non-dilute filler concentration and tailoring effective thermal conductivity by varying filler attributes within the constraints of the shear modulus. Potential polymers and fillers are considered, and high-density polyethylene and thermoplastic polyurethane with ceramic fillers exhibit high thermal conductivity without compromising compliance. The model validates that manipulating filler alignment and aspect ratio contributes significantly to heat-conducting networks in composites for ultra-high thermal conductivity.

Summary: Recent advances in additive manufacturing have allowed for the design and fabrication of auxetic materials with programmable geometries and tailorable properties. This study explores the integration of these materials into composite design by embedding them in cementitious units. The mechanical properties and compressive behavior of the resulting lattice-reinforced cementitious composite (LRCC) units are characterized and compared with those of traditional materials. The results demonstrate that despite weaker 3D-printed materials, the LRCC units exhibit comparable strength and higher energy-absorbing capabilities.

Summary: A thermal conductivity computation model was proposed for carbon fiber reinforced polymer/aramid fiber reinforced polymer bi-material composites. The model validated by thermal response test with a relative error less than 7.5%. The effect of aramid fiber layer thickness and heating temperature on thermal response was discussed, and it was applied to analyze the thermal response under the deep-sea oil-lifting condition. It was found that specimens with more than two layers of aramid fibers showed better thermal insulation, and the higher the heating temperature, the better the thermal insulation effect, especially for specimens with multi-layer aramid fibers.

Summary: The proposed numerical-analytical approach addresses the stress-strain state of bimaterial structures with interphase ribbon-like deformable inhomogeneities under combined force and dislocation loading. It considers the possibility of delamination along the inclusion-matrix interface with dry friction and constructs a structurally modular method of jump functions to handle nonlinear properties of thin inclusions. The system of equations and iterative algorithm developed aim to determine friction-slip zones and investigate the influence of loading parameters and friction coefficient.

Summary: Optically transparent glass fiber-reinforced polymers were successfully produced using a thermoset matrix and E-glass fabric. Through optimization, high mechanical strength and transparency were achieved in the composite, even with a high number of glass fabric layers. Utilizing an L-RTM setup, a remarkable infiltration degree was achieved, maintaining high transmittance levels.

Summary: This study examines the feasibility of recycling glass fiber reinforced polymer (GFRP) and carbon fiber reinforced polymer (CFRP) waste in pervious concrete (PC) and quantifies their environmental impacts through a lifecycle assessment (LCA) framework. Results show that the inclusion of GFRP and CFRP can improve the flexural strength of PC, and the environmental impacts of recycling CW in PC pavement systems are relatively small compared to the production of raw materials.

Summary: Reinforced composite materials have great potential in radiation shielding due to their lightweight, low cost, high resilience, good mechanical tenacity, and interesting electrical properties. Recent literature has criticized the continued use of lead for radiation shielding due to its drawbacks such as high toxicity, poisoning, lack of stability, heaviness, and hazardous afterlife handling.

Summary: The aim of this study was to compare the physical and mechanical properties of a newly developed nano-sized hydroxyapatite fiber-reinforced composite with other composites. The results showed that fiber-reinforced composites had higher hardness and flexural strength, while particle-filled composites had lower volumetric polymerization shrinkage. Additionally, there was a correlation between the content of inorganic filler and hardness as well as volumetric polymerization shrinkage.
