摘要：

The relationship between the glass fiber length and flame retardant of LGF/PBT/RP composites was studied. According to the analysis of optical microscope, combustion properties test, scanning electron microscope (SEM), dynamic thermomechanical analysis (DMA) and mechanical properties, it was found that with the initial length of glass fiber increasing, the effective fiber length distribution of LGF/PBT/RP composites firstly moved toward the longer region of glass fiber, then moved toward the shorter area of glass fiber.Moreover, the dispersion of glass fibers of LGF/PBT/RP composites turned from homogeneous to uneven. With increase of the length of glass fiber, the burning time of vertical burning test (UL-94), average heat release rate (Av-HRR), total smoke release (TSR), total heat release (THR), average effective heat of combustion(Av-EHC) and fire growth rate(FIGRA)of LGF/PBT/RP composite firstly decreased and then increased. The change trend of limiting oxygen index(LOI) was opposite. This behavior indicated that with the effective length of glass fiber increasing, the flame retardant performance of LGF/PBT/RP compo-site was improved, namely, the glass fiber length had an effect on flame retardant performance of LGF/PBT/RP composite. © 2017, Materials Review Magazine.
