Abstract: In recent times, there is considerable interest in the elaboration and use of bio-composites. Agricultural residues are preferred as reinforcements in these composites due to their abundant availability and need to find alternatives to the burning or burying of the residues which are one of the major causes of pollution. Sisal fiber is a widely available natural fiber which possesses excellent moisture and heat resistant properties. Attempts have been made earlier to study the properties of it reinforced with various reinforcements separately and as a hybrid with other fibers. In this study, it is been reinforced with polypropylene and the tensile, flexural and morphological properties have been analyzed. Furthermore, the flame resistance of the prepared composite was also determined. Tensile strength ranging from 22-52 MPa and flexural strength in the range of 57-120 MPa was obtained. The Young’s modulus varied between 1651-5420 MPa whereas the flexural modulus lied in 3064-5462 MPa range. The composites possessed a Rockwell Hardness Number of 58-92 depending on the ratios of reinforcement. Compression molding technique made the work simple and cost-effective to fabricate composites with good mechanical properties. Using the residues in their native form provides an opportunity to add substantial value addition and decrease waste. Simultaneously, a possible substitute for non-biodegradable products can be developed.
