Summary: This study evaluated the effect of multi-wall carbon nanotubes (MWCNT) on polycarbonate/acrylonitrile butadiene styrene/graphene-related materials (GRM) nanocomposites. The electrical behavior of the nanocomposites was found to be closely related to the lateral size, thickness, and production method of the GRM. The use of graphene nanoplatelets with the smallest lateral size and thickness, and the addition of 1.5 wt% MWCNT, achieved the required electromagnetic interference shielding effectiveness (EMI SE) for commercial applications.

Summary: This study evaluated the use of two different aspect ratios (158 and 600) of multi-wall carbon nanotubes (MWCNTs) as nanofillers to improve the electrical, electromagnetic, and mechanical properties of polycarbonate (PC) melt mixed nanocomposites. The MWCNTs with a smaller aspect ratio showed better dispersion and improved electrical and electromagnetic properties in the PC matrix. A content of 2.0 wt% was found to be the optimum for both types of MWCNTs, resulting in an AC electrical conductivity greater than 10(-4) S/cm and higher EMI SE values of 14 dB for the smaller aspect ratio MWCNT and 11 dB for the larger aspect ratio MWCNT.

Summary: There is concern about the increased by-products generated by the high demand for biodiesel. This study investigated the preparation of activated carbons from biodiesel waste (crude glycerin) using chemical activation and microwaves as the heat source. The results showed that the activation time and impregnation ratio were critical factors in determining the specific surface area and pore volume of the activated carbons. Crude glycerin was found to be a promising raw material for preparing activated carbons using microwaves.

Summary: This paper discusses the influence of multiple impacts on the compression strength of honeycomb sandwich structures with composite face sheets. It is found that the size of the impactor affects the turning point of the compression strength. Additionally, high impact energy leads to damage in the bottom face sheet and reduces the overall compression strength.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.

Summary: The vulnerability of natural fibers to heat and fire poses a significant challenge for their substitution of traditional fiber reinforcements in composite materials. Natural fiber/polymer composites (NFCs) are regarded as potential candidates for engineering applications due to their environmental friendliness and low-impact sourcing. Thus, appropriate approaches need to be implemented to enhance the fire safety of NFCs. This review summarizes and discusses the latest understanding of flammability and thermal properties of natural fibers, with a special focus on their interaction with polymer matrix in fire behavior. Additionally, the latest developments in flame-retardant approaches for NFCs are reviewed, covering both flame retardancy and fire structural integrity. Finally, future prospects and perspectives on fire safety of NFCs are proposed, providing insights into further advancements of NFCs.

Summary: Real-time monitoring of carbon fibre composites during Automated Fibre Placement (AFP) manufacturing remains a challenge for non-destructive evaluation (NDE) techniques. This study designed a directional eddy-current (EC) probe to evaluate the detectability of out-of-plane wrinkles. Experimental evaluations and finite element modeling were conducted to better understand the relationship between eddy-current density and defect detection. The findings suggest that the probe configuration with an asymmetric driver coil and differential pickup coils shows the best capability for wrinkle detection.
