| Summary: | 碩士 === 朝陽科技大學 === 應用化學系 === 105 === In this study, woven jute fiber cloth (Jf) was used to reinforce polypropylene (PP), and a commercially available flame retardant was added to increase the application PP. Maleic anhydride grafted polypropylene (MAPP) was added as a compatibilizer. Moreover, Jf was chemically treated and modified by 3-Aminopropyltriethoxysilane to enhance the properties of the composites. The results showed that the absorption peaks of C-Br and Sb2O3 were found in the FTIR spectrum of flame retardant. And the Jf is composed of jute yarn, PE fiber and PP/PE blending fiber. TGA analysis revealed that the decomposition temperatures (Td5 and Td20) of the composites were increased by improving the compatibility of the composites, and char yield was also increased. The results of tensile and impact tests showed that PP/MA/BJf exhibited the best tensile and impact strengths. The results of UL-94 test showed that the flame retardancy of the flame retardant containing composite materials can achieve the highest level (V-0). SEM analysis can be observed that the compatibility between Jf and PP was improved by the chemical treatment of Jf. Based on the above results, Jf reinforced PP composite materials can reinforce PP with low cost, and increase the applications of PP.
