Tensile properties and interfacial strength were quantified by single fiber tensile test and single fiber pull-out test. Characterization techniques including scanning electron microscope (SEM), X-ray diffraction patterns (XRD), Fourier transform infrared spectra (FTIR), gel permeation chromatography (GPC) and differential scanning calorimeter (DSC) were employed to analyze the physicochemical properties. All three fungi thrived on sisal fibers and PLA surfaces, preferring fibers, with <em>Trichoderma longibrachiatum</em> multiplying fastest while <em>Aspergillus niger</em> significantly influencing. Infected fibers underwent three stages: Surface Degradation, Structure Disintegration and Microfibril Destruction. Due to the degradation of components and abundant defect density, the fiber strength and modulus decreased by 79.2 %–86.6 % and 7.6 %–11.8 % respectively, although there was a short-term resurgence, and eventually culminated in the loss of load-bearing. The interface also experienced three stages: Microcrack Initiation, Crack Penetration and Interface Debonding. The deterioration of interface strength with a reduction of about 80.0 % stemmed from the serious fibers’ structure damage and slight matrix degradation considering the molecular weight and thermal properties. This research unlocked the crucial degradation mechanism of PFRCs in fungal environments, providing the experimental foundation for product performance and lifespan prediction.</div></div>","PeriodicalId":10533,"journal":{"name":"Composites Communications","volume":"55 ","pages":"Article 102296"},"PeriodicalIF":6.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143421585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of the relative concentration (<span><math><mrow><msub><mi>φ</mi><mrow><mi>F</mi><mn>2</mn><mi>H</mi></mrow></msub></mrow></math></span>) and the size-to-diameter ratio (SDR) of FG and HGμS on FG exfoliation and the resulting changes in thermal and electrical transport were examined. At low HGμS content, the dilution effect of HGμS on the FG network is dominant, leading to a reduction in thermal diffusivity. This effect can be mitigated by coordinated filler stacking, which suppresses the preferential FG orientation. As the HGμS content increases, FG platelets undergo in-situ exfoliation during melt compounding, leading to improved thermal diffusivity. Moreover, adding HGμS reduces the electrical percolation threshold, particularly when the SDR decreases from 1.3 to 0.6. The stacking structure of HGμS creates a 3D template that confines FG in interstitial regions while exfoliated FG wraps HGμS surfaces, forming continuous, isotropic conductive pathways that promote electron and phonon transport. Although FG exfoliation is not directly correlated with the SDR between FG and HGμS, a higher SDR increases FG concentration per conductive pathway, enhancing electrical conductivity and thermal diffusivity. However, excessive amounts of HGμS will disrupt the network connectivity, leading to decreased thermal and electrical conductivity. These findings highlight the importance of optimizing filler concentrations (per pathway) and network isotropy to enhance the overall thermal/electrical transport in polymer composites.</div></div>","PeriodicalId":10533,"journal":{"name":"Composites Communications","volume":"54 ","pages":"Article 102273"},"PeriodicalIF":6.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143135852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
