Give this article delves into the investigation of the crystal structure and crystalline orientation of composite polyamide 6 (PA6) nanofibers. The study aims to elucidate the impact of crystallinity and crystalline orientation on the properties of composite nanofibers, which were manufactured by the electrospinning process of Nylon 6/formic acid (HCOOH) polymer solutions at concentrations of 16%, 20% and 28%, incorporating 0.25% succinite powder with particle sizes ranging from 5 to 20 nm. The average diameters of the resulting nanofiber mats were systematically measured, revealing dimensions of 50±15 nm, 90±18 nm, and 340±78 nm, respectively. Using wide-angle X-ray diffraction (WAXD) analysis, the study provides a detailed examination of how the concentration of PA6 and the inclusion of organic succinite additives influence the crystal structure and crystalline orientation within the polymer matrix. In particular, it highlights the effects observed at smaller diameters of composite nanofibers, where enhanced macromolecular alignment is coupled with reduced crystallinity, marking the first comprehensive exploration of these phenomena in individual composite nanofibers. Research demonstrates that the relative distribution of different crystalline phases varies among samples with different average diameters. Notably, the sample with the smallest average diameter of 50 nm showcased a singular crystalline peak at 2θ=21.23°, closely aligning with the theoretically reported value for the γ phase (2θ=21.4°). On the contrary, samples with larger average diameters revealed progressively more distinct shoulders on X-ray diffraction patterns, indicative of the α phase. A notable increase of approximately 25% was observed as the diameter of the composite nanofibers decreased. Furthermore, the composite nanofibers of smaller diameter presented a narrower full width at Half Maximum (FWHM), suggesting enhanced orientation for both observed phases. This study not only contributes to understanding of the influence of nanofiber composition and structure on their physical properties but also opens new avenues for the tailored design of nanofiber based composites for advanced engineering applications.

“…It is a thermoplastic polymer that is widely used in various applications such as soil stabilisation due to its versatility, durability, and relatively low cost. Polypropylene fibres are formed when polymer polypropylene is processed into fibres (Hejazi et al, 2012;Hussain et al, 2023). The chemical and physical characteristics of polypropylene fibres are shown in Table 9.…”

Subgrade soil is an essential component in the design of road structures as it provides lateral support to the roadway. One of the main reasons for pavement failure is subgrade settlement, which leads to a loss of subgrade strength. If the mechanical properties of subsoils are lower than required, a soil stabilisation method may be an option to improve the soil properties of the weak subsoil. Soil stabilisation is one of the techniques for improving poor subsoil, which results in significant improvement in tensile strength, shear strength and bearing capacity of subsoil. Soil stabilisation can be broadly divided into four types: thermal, electrical, mechanical, and chemical. The most common method of improving the physical and mechanical properties of soils is stabilisation with binders such as cement and lime. However, soil stabilisation with conventional methods using cement and lime has become uneconomical in recent years, so an alternative such as fibres may be sought. This review provides a comprehensive comparison of the effectiveness of natural fibres and synthetic fibres in stabilising subgrade soils.

The aim of the work described in this paper is to improve the thermal stability and mechanical properties of polypropylene (PP)/styrene‐ethylene‐butylene‐styrene (SEBS)/clay nanocomposites fabricated by fused filament fabrication (FFF). The response surface method is used to investigate the effect of print speed, nozzle temperature, and nano‐clay content on the thermal stability, tensile strength, and impact resistance of the PP/SEBS/clay nanocomposite. In addition, the microstructure of the printed samples was analyzed by SEM and TEM images. Increasing the nano‐clay amount significantly enhanced the melting temperature of the nanocomposite, while increasing nozzle temperature and print speed had a slight influence on the melting temperature. Moreover, the highest tensile strength of the nanocomposite was attained at a clay content of 3 wt%, due to the good distribution of the nanoparticles in the PP matrix. The impact resistance of the nanocomposite was also enhanced with an increase in print speed, while an increase in nozzle temperature and clay content reduced the impact resistance. The optimization results indicated that the melting temperature, tensile strength, and impact resistance of the PP/SEBS/clay nanocomposite can be enhanced simultaneously by a print speed of 80 mm/s, nozzle temperature of 242°C and nano‐clay content of 3.2 wt%.Highlight Fabrication of PP/SEBS/clay nanocomposite using the FFF process.
