摘要：
Char sulfonic acid and ammonium polyphosphate were used to improve the flame retardancy of composites. A synergistic effect between char sulfonic acid and ammonium polyphosphate on the flame retardancy of epoxy resin and polyamide composites was proposed. The results showed that the optimal synergistic effects were achieved when the weight ratio of char sulfonic acid:ammonium polyphosphate was 1:3. Thermogravimetric analysis indicated that the flame retardants improved the amount of residue. The char sulfonic acid and ammonium polyphosphate additives greatly decreased the peak heat release rat...
