• Abstract:Phenolic resin/carbon fiber (PF/CF) composites have good tribological properties; however, their extensive applications are limited because of the poor thermal conductivity of the phenolic resins. In this work, core‑shell particles of polyaniline‐coated (3‐aminopropyl) triethoxysilane‐modified β‐Si3N4 (m‐SiN@PANI) were used to enhance the tribological, electrical, and thermal conductivity properties of a PF/CF composite. A core‑shell particle, consisting of m‐SiN@PANI, was characterized by Fourier Transform Infrared Spectrometry, X‐Ray Diffraction, Scanning Electron Microscope, and Transmission Electron Microscope. The friction, thermal, and electrical properties of the composites were characterized by multifunctional vertical friction testing, wear measurement testing, thermogravimetric analysis, thermal constant analysis, and electrical conductivity testing. Remarkably, the test results showed that compared with the wear surface of the PF/CF composite, that of the phenolic resin/(2.0 wt % m‐SiN@PANI)/carbon fiber composite exhibited a smoother morphology. The results indicated that the addition of m‐SiN@PANI effectively improved the thermal conductivity, electrical conductivity, friction coefficient, and wear rate of the composites, which were 3.164 Wm−1 K−1, 5.33 × 10−6 S/m, 0.1681 and 1.13 × 10−8 mm3/Nm, respectively.
