Summary: Polyhedral oligomeric silsesquioxane (POSS) copolymerized with butyl acrylate (BA), methyl methacrylate (MMA), and acrylic acid (AA) resulted in a twofold increase in fracture energy and Young's modulus of cast films at 1 wt% content. The dispersion of POSS in the acrylic matrix and its intercalation within the molecular mesh contributed to the increase in entanglement density, leading to enhanced mechanical reinforcement and resistance to fracture.

Summary: The 2D few-layered Ti3C2Tx MXene nanosheets were prepared through etching and delamination of aluminium layers from the Ti3AlC2 MAX phase. The electroactive polyamide (EPA)/Ti3C2Tx MXene nanocomposites (NCs) containing various amounts of MXene were synthesized via in-situ oxidative coupling polymerization. The NCs showed improved physical properties such as electrical conductivity, thermal stability, and adhesion strength due to the close interaction between EPA and MXene. The addition of Ti3C2Tx MXene did not affect the surface roughness and water contact angle of the EPA matrix. The NCs coated samples exhibited improved tribological properties, and the corrosion study demonstrated excellent corrosion protection ability of EPA/Ti3C2Tx MXene NCs containing 1.2 wt% MXene.

Summary: A comprehensive thermal degradation analysis was conducted on pure bio-polymer and dimer fatty acid-based polyamides-polyhedral oligomeric silsesquioxane (BP-POSS) nanocomposite to evaluate their thermal degradation through kinetics. BP-POSS nanocomposites were prepared using biodegradable biopolymer and 12.5 wt% of POSS nanomaterial. The physical coordination between the polymer and POSS nanomaterial in the prepared nanocomposites was analyzed. Dielectric properties and activation energies were measured for both pure-BP and BP-POSS nanocomposites. The remarkable thermal stability of BP-POSS 12.5 wt% nanocomposite was observed due to the reinforcement of POSS molecules. A nth order reaction kinetic model was proposed for the degradation process of pure BP and its POSS nanocomposites, and the model was validated by correlating experimental and simulated conversion thermogram.

Summary: In this study, a difunctionalized cyanate ester double-decker silsesquioxane (DDSQ-OCN) cage was prepared to improve the thermal behavior of epoxy resin. The covalently bonded network structure formed by the copolymerization of epoxy and OCN units, as well as the hydrogen bonding between the OH groups of epoxy and the SiOSi moieties of DDSQ units, enhanced the physical properties of the material. The addition of Cu(II)-acac accelerated the thermal polymerization process but decreased the thermal stability.

Summary: This study focuses on the potential use of recycled PETG as a matrix material in continuous fiber additive manufacturing of composites. By comparing the characteristics of rPETG with non-recycled PETG and conducting tests on the printed composites, it was found that rPETG-based composites have lower tensile properties but similar flexural properties compared to PET-based composites. The research also showed that the adhesion between rPETG and CC was higher than that of PETG and CC, indicating the potential of recycled plastics to be converted into circular products of high added value.

Summary: The production of petroleum-based polymers poses a threat to the ecosystem and oil reserves, leading researchers to explore the use of biodegradable polymers as an alternative. However, poly(lactic acid) (PLA), considered the most suitable substitute, has limitations such as slow crystallization rate, low thermal stability, high brittleness, and low toughness. To overcome these deficiencies, researchers have developed techniques like blending with other polymers or using nanofillers, with polyhedral oligomeric silsesquioxanes (POSS) being the most promising nanofiller. This article reviews investigations on incorporating POSS into PLA or PLA blends, comparing the improved composites with neat PLA in terms of mechanical, morphological, and physical properties.

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.

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.
