Highlights In this work, silicone polymer (PSOL)/glass fiber (GF)/epoxy (EP) composites were prepared by employing PSOL as interfacial modifier into GF/EP composites. The mechanical and dynamic mechanical properties of the composites were investigated to determine the optimal PSOL content. The effect of PSOL on the wettability of EP on GF was investigated. The micromorphology of the GF/EP composites was also examined by scanning electron microscope. The results demonstrate that the interfacial bonding between GF and epoxy resin was improved significantly by the addition of PSOL. Specifically, the interlaminar shear strength, tensile strength, elongation at break, and blending strength of the PSOL/GF/EP composites increased by 9.28%, 13.61%, 12.66%, and 19.22%, respectively. Moreover, the original thermal stability of the composites was improved by the incorporation of PSOL. This study highlights the effectiveness of PSOL as an interfacial modifier, enhancing the overall performance of GF/EP composites while improving their thermal stability. Silicone polymer (PSOL)/glass fiber (GF)/epoxy (EP) composite material is made of glass fiber and epoxy resin by hand paste molding. Silicon polymers as interface modifiers can improve the interface between glass fiber and epoxy resin. PSOL/GF/EP composites have good mechanical properties. The glass transition temperature of GF/EP composites was increased by silicon polymer. [ABSTRACT FROM AUTHOR]

In this work, carbon nitride (C3N4) powder was oxidized by the Hummers oxidation method, and oxidized carbon nitride (O‐C3N4) was obtained. Epoxy (EP) was modified with O‐C3N4, and then carbon fiber fabric/epoxy (CF/EP) composites were prepared by hand‐pasting molding. The O‐C3N4 greatly improves the wettability of EP resin, enhances the interface properties of CF/EP composites, and makes the composites have better mechanical properties. The interlaminar shear strength (ILSS) is increased from 51.75 to 59.68 MPa, the tensile strength is increased from 564.54 to 635.39 MPa, the bending strength is increased from 809.64 to 938.81 MPa, and the impact strength is increased from 73.48 to 84.84 kJ/m2. Meanwhile, the dynamic mechanical properties of composites are also significantly improved. The energy storage modulus is increased from 14.9 to 21.4 GPa, with an increase of 43.6%. Highlights: Developing carbon fiber composites is conducive to industrial applications.O‐C3N4 effectively improves the mechanical properties of the composite.O‐C3N4 has the advantages of simple synthesis, low costs, and light color.O‐C3N4 is rich in oxygen‐containing functional groups.

Interleukin (IL)‐17A is pro‐inflammatory cytokine which has been identified as a noninvasive marker of the pathogenesis of non‐alcoholic steatohepatitis (NASH). However, the underlying role of IL‐17A in NASH progression remains unclear. This study was designed to investigate the biological function and molecular mechanism of IL‐17A in the induction of NASH. The results showed that IL‐17A was highly expressed in high‐fat diet (HFD)‐induced NASH mouse model. Intravenous injection of IL‐17A exacerbated steatohepatitis process via promoting hepatocyte apoptosis. Furthermore, IL‐17A‐induced apoptosis was mediated by ERK1/2/p65 signaling pathway. In conclusion, we demonstrated that IL‐17A‐mediated ERK1/2/p65 signaling pathway was a promising target for the treatment of NASH. © 2018 IUBMB Life, 71(3):302–309, 2019 [ABSTRACT FROM AUTHOR]
