Special Issue Information

Dear Colleagues,

In the realm of cutting-edge engineering, the imperative to develop advanced materials with superior properties has reached a paramount status. Fibrous composites, highly esteemed for their low specific gravity, enhanced strength, increased stiffness, heightened corrosion resistance, extended life cycle, and, notably, their lightweight structure, emerge as pivotal in this pursuit. Beyond these intrinsic advantages, the captivating attributes of design flexibility, consolidation feasibility, and multifunctionality solidify the prominence of these materials in advanced engineering. Consequently, the exploration of fabricating and evaluating the performance of fiber-reinforced composites assumes multifaceted significance. This endeavor not only contributes to the optimization of these composites but also underscores their indispensable role in addressing industry-specific requirements through a nuanced understanding of fabrication techniques.

The primary objective of this Special Issue is to bring together cutting-edge research on the fabrication and performance evaluation of fiber-reinforced composites. We seek to explore the diverse aspects of this field and highlight its significance in addressing contemporary challenges.

Original research articles and reviews are eagerly welcomed for this Special Issue. Submissions may delve into a range of research areas, including but not limited to:

(i) Novel fabrication techniques for fiber-reinforced composites.
(ii) Performance evaluation methodologies and testing protocols.
(iii) Innovations in composite material design and optimization.

We look forward to receiving your valuable contributions, which will undoubtedly enrich the discourse surrounding the fabrication and performance evaluation of fiber-reinforced composites.

Loess is widely distributed in the northwest and other regions, and its unique structural forms such as large pores and strong water sensitivity lead to its collapsibility and collapse, which can easily induce slope instability. Guar gum and basalt fiber are natural green materials. For these reasons, this study investigated the solidification of loess by combining guar gum and basalt fiber and analyzed the impact of the guar gum content, fiber length, and fiber content on the soil shearing strength. Using scanning electron microscopy (SEM), the microstructure of loess was examined, revealing the synergistic solidification mechanism of guar gum and basalt fibers. On this basis, a shear strength model was established through regression analysis with fiber length, guar gum content, and fiber content. The results indicate that adding guar gum and basalt fiber increases soil cohesion, as do fiber length, guar gum content, and fiber content. When the fiber length was 12 mm, the fiber content was 1.00%, and the guar gum content was equal to 0.50%, 0.75%, or 1.00%, the peak strength of the solidified loess increased by 82.80%, 85.90%, and 90.40%, respectively. According to the shear strength model, the predicted and test data of the shear strength of solidified loess are evenly distributed on both sides of parallel lines, indicating a good fit. These findings are theoretically significant and provide practical guidance for loess solidification engineering. Full article

The application of alginate fibers is limited by relatively low mechanical properties. Herein, a self-reinforcing strategy inspired by nature is proposed to fabricate alginate fibers with minimal changes in the wet-spinning process. By adapting a coagulation bath composing of CaCl2 and ethanol, the secondary structure of sodium alginate (SA) was regulated during the fibrous formation. Ethanol mainly increased the content of β-sheet in SA. Rheological analysis revealed a reinforcing mechanism of stiff β-sheet for enhanced modulus and strength. In combination with Ca2+ crosslinking, the self-reinforced alginate fibers exhibited an increment of 39.0% in tensile strength and 71.9% in toughness. This work provides fundamental understanding for β-sheet structures in polysaccharides and a subsequent self-reinforcing mechanism. It is significant for synthesizing strong and tough materials. The self-reinforcing strategy involved no extra additives and preserved the degradability of the alginate. The reinforced alginate fibers exhibited promising potentials for biological applications.
