This work presents an investigation of the mechanical properties of a composite structure manufactured frompolypropylene matrix reinforced with jute waste fibres collected from textile industry with extrusion followed by injectiontechniques. Mechanical tests under uniaxial strain shows that this lightweight vegetal fibre significantly enhanced themechanical performances of the whole composite with a very slight quantity of compatibilizer which positively influencesthe final price of the composite. The fracture surfaces showed highly tethered as well as weakly anchored fibres to thematrix. Moreover, in order to have a deep insight on that anchoring behaviour, uniaxial tensile deformation was appliedunder Scanning Electron Microscopy and evidenced how the fibre/matrix interface plays a high role to strengthen thewhole structure. The fibre and matrix interface is not simply resumed to high or weak anchoring but there is acombination of sticking and slipping of reinforcement on the polymeric walls.
