“…These fiber bundles are held together by interfaces composed of pectin, hemicellulose, and lignin. Consequently, the presence of waxy layers and protrusions on the surface is clearly evident [ 46 , 47 , 48 ]. In Figure 3 b, the image depicts CSFs that have been treated with stearic acid, resulting in a stearic acid coating on the surface of the fibers.…”

“…Figure 5 c1,c2 depict the impact fracture surfaces of alkali-treated cotton stalk fiber composites (N-CSF), revealing a rough surface with numerous mechanical anchor points on the CSFs. The effect of fiber plucking caused by impact is evident from the presence of rough impact surfaces and significant deformation surfaces [ 38 , 41 , 46 , 47 , 48 ]. The microstructure of impact fracture surfaces of cotton stalk fiber composite (S-CSF) treated with a silane coupling agent is depicted in Figure 5 d1,d2.…”

“…On the other hand, the presence of a silicon film on the surface of silicon-treated CSFs, due to its unique O-Si-C structure, imparts greater stability compared with the C-C structure alone. As a result, it significantly improves the material’s thermal stability [ 44 , 48 , 49 , 60 ]. The cotton stalk fiber composite treated with alkali/silane (SN-CSF) undergoes an initial alkali treatment, which effectively removes the easily decomposable unstable hemicellulose and pectin components, thereby enhancing the surface roughness.…”

Different chemical treatment methods were employed to modify the surface of cotton stalk fibers, which were then utilized as fillers in composite materials. These treated fibers were incorporated into polylactic acid/polypropylene melt blends using the melt blending technique. Results indicated that increasing the surface roughness of cotton stalk fibers could enhance the overall mechanical properties of the composite materials, albeit potentially leading to poor fiber–matrix compatibility. Conversely, a smooth fiber surface was found to improve compatibility with polylactic acid, while Si-O-C silane coating increased fiber regularity and interfacial interaction with the matrix, thereby enhancing heat resistance. The mechanical properties and thermal stability of the composite materials made from alkali/silane-treated fibers exhibited the most significant improvement. Furthermore, better dispersion of fibers in the matrix and more regular fiber orientation were conducive to increasing the overall crystallinity of the composite materials. However, such fiber distribution was not favorable for enhancing impact resistance, although this drawback could be mitigated by increasing the surface roughness of the reinforcing fibers.

Resource depletion and environmental degradation have become important issues affecting the human development process. Plant fiber‐reinforced composites (PFRCs) are characterized by high natural availability, good mechanical properties, low density, recyclability, and eco‐friendliness. Expanding human applications of plant fibers is an important measure to combat resource and environmental problems. The injection molding process has the characteristics of strong product size adaptability, high molding precision, and high production efficiency. It is suitable for large‐scale production in the industry and is one of the main molding methods of PFRCs. Currently, there are still challenges and opportunities for high‐performance manufacturing of PFRCs based on the injection molding process. This article reviews the complete process of manufacturing‐service life‐remanufacturing of PFRCs based on the injection molding process. Emphasis is placed on the pretreatment technology and selection strategy of multi‐phase blended raw materials, the molding process conditions, functional applications, and simulation analysis, the aging and degradation characteristics during service, and the remanufacturing characteristics of the composites. Finally, the future research focus is summarized and prospected. The research in this paper will help promote the continuous progress of key technologies in the production process of PFRCs and help the industry to truly realize high‐performance green manufacturing in the future.Highlights Plant fibers exhibit variability in morphology and properties. The link between the structure and performance of PFRCs is unclear. The degradability and durability of PFRCs are contradictory. The functionality and mechanical properties of PFRCs are contradictory. PFRCs have good characteristics for remanufacturing.
