Different kinds of flame retardant and toughened glass fiber (GF)-reinforced polycarbonate composites were fabricated through melt extrusion blending and injection molding. Methacrylate-butadiene-styrene (MBS), styrene-maleic anhydride (SMA), ethylene methylacrylate (EMA), and silicon acrylate rubber (SiR) were used as toughness modifiers. Two kinds of aryl phosphorus, namely, triphenyl phosphate (TPP) and resorcinol bis(diphenyl phosphate) (RDP), and oligomeric siloxane-containing potassium dodecyl diphenylsulfone sulfonate (SiKSS) were adopted as flame retardants (FRs). The V-notched Izod impact test revealed that SiR could significantly improve the toughness of GF-reinforced polycarbonate composites. The flame retardancy of FR PC/GF/SiR composites was investigated by the UL-94 vertical burning test. The FR PC/GF/SiR composites showed good flame retardancy with a V0 rating when 9 wt% TPP, 6 wt% TPP/RDP, or 0.2 wt% SiKSS was added. The effect of the FRs on the mechanical properties, rheological properties and heat deflection temperature of PC/GF/SiR composites was also investigated.
