The objectives and novelty of this paper are to create a hybrid-natural fibre composite by the Response SurfaceMethodology RMS technique, and then compared this hybrid composite with the individual fibre reinforced composites inthe bending test. The first aim of this study is devoted to analyse, modelize and optimise the various independent variablessuch as the type of fibres (X1), the types of chemical treatment (X2), the volume fraction of fibre (X3) and the treatmentduration (X4) used on the output parameters which are the mechanical characteristics namely, ultimate flexural stress andflexural modulus in the bending test using a Box-Behnken experimental design. Mathematical models for ultimate flexuralstrength and flexural modulus were developed using the response surface methodology (RSM). These models would behelpful in selecting independent variables in order to maximize the flexural mechanical properties. Statistical analysis of theresults showed that selected variables had a significant effect on the flexural properties, except the treatment time that has avery weak significance effect on the flexural properties. In the second section, the impact behaviors of the natural hybridcomposites found by the RMS method were confirmed experimentally. Finally, the experimental results indicate that theflexural properties of the natural hybrid composites increase with an increase in the composition of jute fibres.
