The composites of biodegradable Polypropylene (PP) reinforced with short jute fiber were prepared by melt mixing followed by hot press molding. The composites were prepared with the aim to develop new biodegradable materials for different applications. Jute fiber is well known for its biodegradable properties but PP is not biodegradable material. The combination of the two materials will lead to the biodegradable properties in some extent as well as higher mechanical properties. The mechanical properties, thermal properties, micro structural analysis and morphologies of the composites were studied via UTM (Universal Testing Machine), Thermo gravimetric analysis (TGA) and Scanning electron microscopy (SEM) respectively. The mechanical properties like tensile strength (TS), tensile modulus (TM), flexural strengths (FS) and flexural modulus (FM) were measured for both treated and untreated specimens and compared. The results show that alkali treated jute reinforced composites have much better properties than the untreated one. The TS, TM, FS and FMwere decreased with increasing of untreated fiber and increased with the increasing of treated fiber in PP-Jute composites (PPJC). The changes in the mechanical properties were broadly related to the accompanying modifications and interfacial bonding of PPJC. Scanning Electron Microscopic image observations indicated good interfacial contact between the short jute fiber and PP matrix. Thermal analysis (TG /DTG) revealed that the introduction of short jute fiber led to a slightly improved thermo oxidative stability of PP-Jute composites.
