  Abstract

To obtain an alternative material with a flammability performance for automotive and building applications, the addition of diammonium phosphate (DAP) and titanium dioxide nanoparticles (TiO2) to polypropylene (PP) composites reinforced with short pineapple leaf fibers (PALF) from agro-waste pineapple leaves was accomplished. The results of thermogravimetric analysis showed that the presence of DAP and TiO2 achieved the formation of char residues and more compact char layers during the pyrolysis condition, thus improving the thermal stability of composites. According to the UL- 94 horizontal burn test, after introducing DAP and TiO2 into the systems, better anti-dripping phenomenon, slower-burning rate, and longer-lasting protection with the higher quality char formation were remarkably evident during the burning process. The water adsorption capacity was reduced significantly by the addition of TiO2 alone and mixed with DAP into the composites. The decline in the flexural strength of composites was due to the non-uniform dispersion of TiO2 in the polymer matrix. Moreover, the investment of the production of PP/PALF composite containing DAP and TiO2 is economically feasible because the net present value (NPV) is 4,589,130 Baht, the Internal Rate of Return (IRR) is 18.69 %, and the payback period is 4 years and 11 months. In summary, PP/PALF composites modified with 5 wt% DAP and 5 wt% TiO2 constituted an effective system with enhanced thermal and flammability performance.
