Here, a series of novel carboxylated waterborne PI sizing agents with different aliphatic ratios were designed to construct a rigid-flexible gradient interphase for the purpose of promoting interfacial adhesion between CF and PEEK. It was observed that the mechanical properties of the composites were optimal when the molar ratio of rigid diamine monomer to flexible diamine monomer reached 7:3. Significant augmentation was observed in various mechanical and interfacial properties, including tensile modulus (25.6 %), tensile strength (19.8 %), flexural modulus (28.5 %), flexural strength (15.8 %), impact strength (24.3 %), and IFSS (57.8 %). Furthermore, the tensile strength of the composites exhibited a greater increase (27.2 %) at elevated temperatures, thus indicating that the role of the interfacial layer was more pronounced at high temperatures. The interphase was analyzed by peak force quantitative nanomechanical imaging (PF-QNM) mode of atomic force microscopy (AFM), the results indicated the formation of a modulus transition zone between the CF and PEEK. This zone exhibited a gradient change of modulus, enabling the composite to transfer and distribute applied loads more effectively when subjected to external forces. Consequently, the findings of this study demonstrated the potential of waterborne PI sizing agents for application on CF, offering a promising avenue for surface modification of high-performance CF/PEEK composites.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"298 ","pages":"Article 112388"},"PeriodicalIF":12.7,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these, fiber-reinforced plastics are widely utilized owing to their excellent mechanical properties. Resin transfer molding—a method for manufacturing thermoset composites—is susceptible to dry spots, which degrade the mechanical properties. Accurately identifying and predicting the flow front can enhance process robustness, ensuring defect-free composites. This study presents a novel approach for identifying flow fronts in real time and predicting flow-front scenarios using a tree model and a generative adversarial network (GAN). First, the changes in electrical resistance during infusion were investigated by examining the electromechanical behavior. Subsequently, by leveraging the electrical resistance data, linear equations were formulated to identify the locations of flow fronts between the electrodes. Finally, possible flow-front configurations were identified across three sections, encompassing 17 scenarios, using the developed identification model. Flow-front prediction was conducted using the tree model, which evaluated all 17 scenarios and tracked the most relevant scenarios according to probability. Additionally, the GAN generated more realistic flow-front configurations, enhancing both the identification and prediction of the flow. This model can reflect the racetracking effect without considering the permeability of the fiber preform, significantly reducing the computational cost compared with numerical simulations. Moreover, the flow-front prediction model effectively mirrored the experimental results, outperforming numerical simulations in both adaptability and speed. By utilizing this model, operators can identify defects such as dry spots in real time and predict their locations using the predicted flow-front configuration.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"298 ","pages":"Article 112382"},"PeriodicalIF":12.7,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyzed one commercial grade with 30 wt% carbon fiber and two lab-compounded grades with lower carbon fiber contents (5 and 15 wt%) using X-ray Micro Computed Tomography (μCT) and calorimetry technologies. μCT analyzed the volume fractions of PEEK resin, carbon fibers, and voids formed during processing. The carbon fiber content was also determined based on the volumetric fraction of each component. Using differential scanning calorimetry (DSC) and fast scanning calorimetry (FSC), the overall crystallization kinetics were extracted for neat PEEK and its carbon fiber composites over a wide range of crystallization temperatures from 160 °C to 330 °C. All kinetics data were fitted well using the Hoffman-Lauritzen model to extract values for <em>U^∗</em>, <em>K</em>_<em>0</em>, and <em>K</em>_<em>G</em>. The results indicate that the energy barriers associated with chain segment mobility <em>U^∗</em> and nucleation <em>K</em>_<em>G</em> do not significantly change with the presence of carbon fiber. However, <em>K</em>_<em>0</em>, associated with the nucleation constant, decreases linearly with increasing non-resin volume fraction. Morphological investigations using scanning electron microscopy (SEM) and Fast Scanning Calorimetry - Atomic Force Microscopy (FSC-AFM) demonstrate the presence of weak surface nucleation and impingement effects from carbon fiber on PEEK resin crystallization.

This research uses a novel approach for reusing post-consumer polyethylene terephthalate (PET) by developing recycled composites from post-consumer PET carpet (cPET) and recycled PET (rPET) resin sourced from bottle discards via compression molding. Incorporating whole carpets in the process significantly reduces preprocessing costs and time. A design of experiments approach was employed with variables such as temperature, pressure, dwell time, and composition to optimize mechanical properties. A two-level fractional factorial design for screening followed by a three-level full factorial design was performed to identify suitable processing parameters to achieve better mechanical properties. The optimal molding processing conditions for rPET/cPET (30/70) composites were identified as 270 °C for 250 s under 1 MPa, which yielded a flexural strength of 54.6 ± 6.0 MPa and a flexural modulus of 3180 ± 110 MPa, as verified through reproducibility testing on 10 samples (2 samples each from 5 molding experiments). These enhanced mechanical properties showcase the potential of rPET/cPET composites for structural applications.
