摘　　要：The effect of vinyltrimethoxysilane(VTMS)graft and SiO_(2) on the structure and mechanical properties of silane-grafted-polyethylene/SiO_(2)(VTMS-g-PE/SiO_(2))nanocomposite fibers and ropes was studied.Scanning electron microscopy(SEM),Fourier transfer infrared(FT-IR),differential scanning calorimetry analysis(DSC)and tensile mechanical tests were performed to characterize the morphology,thermal and mechanical properties of nanocomposite fibers and ropes.The results revealed that the SiO_(2) nanoparticles were well dispersed throughout the polymeric matrix.With increasing SiO_(2) content,T_(m),the melt peak width and X_(c),degree of crystallinity,of VTMS-g-PE/SiO_(2) nanocomposite fibers increased.The breaking load and breaking strength of the nanocomposite fiber ropes were remarkably improved compared to pure PE fiber ropes and elongation at break was also decreased.
