“…The mechanical properties of the lled polymer composites are of great signicance in practical applications, but are generally deteriorated due to serious agglomeration under high lling content. 45,46 The tensile test of the PI lm and PI composite lms was conducted to investigate the tensile strength of different composite lms, and evaluated the exibility of the Al 2 O 3 @BN&BN/PI composite lm. As shown in Fig.…”

Under vacuum Al-Mg alloy, liquids were successfully infiltrated into carbon/carbon (C/C) composites at high temperatures. Then, the mechanical properties, the metallographics, the scanning electron microscope images, the transmission electron microscope images, the X-ray diffraction images, and the energy dispersive spectroscopy results of C/C-Al-Mg composites were analyzed. The result showed that the bending property of C/C-Al-Mg composites reached 183 MPa whereas that of C/C composites totaled 165 MPa. The compressive strength of C/C-Al-Mg measured 206 MPa whereas that of C/C composites amounted to 142 MPa. The flexural strength and compressive strengths of the steeped metal sliders measured 121 and 104 MPa, respectively. The alloy liquid infiltrated into the matrix by forming a "network conduction" structure which reduced the resistivity and improved the conductivity of the composites. The resistivity of C/C-Al-Mg totaled 1.63 µΩm whereas that of C/C was 3.56 µΩm. During infiltration, an excellent wettability was observed between Al and the carbon matrix due to the existence of Al 4 C 3 . The friction coefficients of C/C, the steeped metal slide, and C/Al-Mg were 0.152, 0.068, and 0.189, respectively. The properties of C/C-Al-Mg composites meet the performance requirements of locomotive pantograph sliders.

Increasing the interfacial adhesion with compatibilizer has been proved to be an effective method to enhance the mechanical properties of composites. In this paper, sodium methacrylate (NaMAA) was introduced to enhance the interfacial adhesion between polypropylene (PP) and ethylene propylene diene monomer (EPDM) via the peroxide‐induced dynamic vulcanization. NaMAA‐induced compatibilization enhanced the phase interface efficaciously and reduced the diameter of EPDM particles from ~8 to ~4 μm. Silica (SiO2) was used in the matrix to improve the mechanical properties of the thermoplastic vulcanizates (TPVs). It was found that SiO2 had little influence on the compatibility between EPDM and PP; however, it improved the tensile strength and stiffness of the TPVs without a severe reduction in the elasticity. The interfacial compatibility of modified EPDM/PP TPVs was verified by Fourier transform infrared, rubber process analyzer, and scanning electron microscope. With 3 wt% of NaMAA and 12 wt% of SiO2, the tensile strength improved from 8.5 to 12.7 MPa and the elongation at break was ranged from 320% to 410%.
