Summary: By studying the rheological properties of UF-WFPE under continuous deformation, a modified plug flow model was proposed to explain the rheological behavior of UF-WFPE melt. The study found that specimens with 70 wt%, 75 wt%, and 80 wt% WF displayed a stable rheological behavior period during compression, while those with 90 wt% WF entered a continuous fracture stage, lacking a stable rheological behavior period.

Summary: A facile strategy for effectively constructing in-plane and through-plane thermal conduction paths in polyimide (PI) and its flexible copper clad laminates (FCCLs) was reported by incorporation of hexagonal boron nitride (h-BN) in a controlled manner. The specific sea-island architecture allowed the preparation of highly thermally conductive flexible PI film and its FCCLs at relatively lower total boron nitride loading. The results of the current work may open a new avenue for promoting the practical application of thermally conductive PI based FCCLs.

Summary: This study investigates the rheological properties of wood polymer composites (WPC) with a polypropylene matrix. The influence of fillers on additional pressure losses caused by entrance effects is analyzed. Tests are conducted using a capillary rheometer and a rheological head, with apparent shear rates up to 101 860 s-1. The study determines the effect of Bagley corrections on the apparent viscosity curve of the tested composites. It is observed that the increase in filler content and shearing rate leads to a significant increase in pressure losses. Thus, considering pressure losses is necessary in rheological measurements of WPC using capillary rheometers.

Summary: The use of neat and recycled polypropylene matrix materials in wood-polymer composites showed different creep properties. The composites with neat polypropylene matrix exhibited superior creep resistance due to higher crystallinity and better interfacial adhesion caused by the formation of a transcrystalline layer. Compared to composites with recycled polypropylene matrix which does not form a transcrystalline layer, composites with neat polypropylene matrix had a 25% reduction in creep compliance. However, from 20 wt.% on, the creep compliance of composites with recycled polypropylene matrix was comparable or even surpassed that of unfilled neat polypropylene matrix, making it a promising way to promote sustainability.

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.
