In this study, the combustibility of five types of plastic plates, fiber reinforced plastic (FRP), polystyrene (PS), polycarbonate (PC), polypropylene (PP), and polyvinyl chloride (PVC), were tested using a cone calorimeter (ISO 5660). The PVC plate showed a 44.65 kW/m lower peak heat release rate (HRR) and a 30.97 kW/m lower maximum average rate of heat emission than the other four types of plastics, whereas the PS plate showed a 773.44 kW/m higher peak HRR and 399.14 kW/m higher maximum average rate of heat emission. The PC plate and PS plate showed the highest HRR by a maximum of 3.88 times in COmean yields, while the PS pate and PP plate showed the highest HRR by a maximum 4.88 times in CO2mean yields. In addition, the smoke performance index (SPI) of the PS plate decreased by 74.81%∼ 95.99%; the smoke growth index (SGI) increased to 76%∼300%; the smoke intensity (SI) also increased to 917.73% ∼ 9607.57%, and the danger of smoke increased. The PS plate was found to have the highest risk of life damage due to smoke on the thermal and smoke sides.
