A study on interfacial properties of jute-PP composites

In this work jute fiber has been treated with Maleic Anhydride grafted PP (MAgPP) and also Vinyl trimethoxy silane (VTMO) at various concentration levels and the tensile, interfacial, and moisture regain properties of the composites are studied in detail. Tensile and flexural tests are carried out to characterize the mechanical properties and fiber pull out test is carried out to characterize the interfacial properties. It has been found that both MAgPP and VTMO treatments improve the tensile properties of the resultant composites. MAgPP treatment yields higher increase in composite tensile properties. Fiber pull out tests also indicate better interfacial strength for MAgPP treated fibers. The influence of fiber volume fraction on tensile and flexural properties is carried out for composites with MAgPP treated jute fibers.
