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.

“…Though there are multiple homogenization methods 45 for the property evaluation of materials, many of those models are developed for applications at a microstructure level, which is not a good representation of the variable microstructures found on larger structures or parts. As porous materials can be compared with composites, some of the constitutive models used to evaluate the mechanical response of porous materials adapt to the mean-field Eshelby-based homogenization method.…”

This research significantly enhances the applicability of thermoplastic olefins (TPOs) in the automotive industry using supercritical N2 as a physical foaming agent, effectively addressing the limitations of traditional chemical agents. It merges experimental results with simulations to establish detailed material‐process‐microstructure‐performance (MP2) relationships, targeting 5–20% weight reductions. This innovative approach labeled digital lifecycle (DLC) helps accurately predict tensile, flexural, and impact properties based on the foam microstructure, along with experimentally demonstrating improved paintability. The study combines process simulations with finite element models to develop a comprehensive digital model for accurately predicting mechanical properties. Our findings demonstrate a strong correlation between simulated and experimental data, with about a 5% error across various weight reduction targets, marking significant improvements over existing analytical models. This research highlights the efficacy of physical foaming agents in TPO enhancement and emphasizes the importance of integrating experimental and simulation methods to capture the underlying foaming mechanism to establish material‐process‐microstructure‐performance (MP2) relationships.Highlights Establishes a material‐process‐microstructure‐performance (MP2) for TPO foams Sustainably produces TPO foams using supercritical (ScF) N2 with 20% lightweighting Shows enhanced paintability for TPO foam improved surface aesthetics Digital lifecycle (DLC) that predicts both foam microstructure and properties DLC maps process effects & microstructure onto FEA mesh for precise prediction

“…They extracted three parameters of the skin-core structure model from the injection molding simulation results and established the relationship between microstructure parameters and mechanical properties using proxy modeling technology. Zhao [30] et al utilized industrial CT to acquire the fiber orientation distribution in a skin-core structure sample. They subsequently separated the sample into five layers and developed a numerical modeling calculation method for the RVE with a particular fiber orientation, based on the lamination structure.…”

The extrusion procedure used to manufacture Short Fiber Reinforced Composites (SFRCs) results in significant anisotropy in the components due to the skin-core structure. While there are existing accurate stiffness prediction methods available, there is still a need in engineering for an efficient and cost-effective prediction method. This work proposes an efficient, low-cost and effective stiffness prediction method for skin-core structure using the orientation averaging method and series-parallel model. Initially, the sample underwent analysis using industrial CT and metallographic microscopy to ascertain the fiber characteristics and skin-core dimensions. Furthermore, it is presumed that the skin and core are distinct materials, and their stiffness is determined using the orientation averaging method. Finally, the stiffness of the sample was determined by employing a series-parallel model for analyzing stress-strain transmission, which involved merging the skin and core components. Experimental and finite element results confirm the method's accuracy, boasting a calculation time of 31.36 seconds and a maximum stiffness error below 10%. This method is expected to be applied to automotive, construction, and other engineering fields to meet the demand for fast, cost-efficient, and effective stiffness prediction of SFRCs.
