Sin embargo, es fundamental garantizar el cumplimiento de los requisitos mecánicos.Una de las razones principales que impulsa el uso de este tipo de fibras, en lugar de las fibras sintéticas, está relacionada con algunas tendencias recientes, como la reducción de peso, que está </span><span style="text-align: center; font-size: 75%;">ligada con su menor densidad. Además, la reducción de peso también contribuye, indirectamente, a la sostenibilidad y la disminución de las emisiones de gases de efecto invernadero, ya que hace posible reducir el consumo de combustible de los transportes.Sin embargo, debido a las diferentes polaridades verificadas entre los polímeros termoplásticos apolares, como el polipropileno (PP), y las fibras naturales, como el papel kraft, se realizó un estudio del efecto de los tratamientos físicos y químicos de la superficie para verificar su influencia en las propiedades de la interfaz fibra-matriz.</span>

Estos resultados inducen un aumento de la compatibilidad de la interfaz entre la matriz y el papel kraft.</span>

−	\| rowspan='2' style="vertical-align: top;"\|<span style="text-align: center; font-size: 75%;">The transports industry has been presenting a set of solutions that integrates natural fibers and their compatibility with structural materials, like polymers. However, it is fundamental to ensure the fulfillment of mechanical requirements. One of the main reasons that is driving the use of this type of fibers, instead of synthetic fibers, is related with the some actual trends, such as weight reduction, which is linked with its lower density. Moreover, weight reduction also contributes, indirectly, to the sustainability and decrease of greenhouse gases emissions, since it makes possible to reduce the fuel consumption of transports.However, due to the different polarities verified between apolar thermoplastic polymers, such as polypropylene (PP), and natural fiber reinforcements, such as kraft paper, a study of the effect of physical and chemical surface treatments was carried out in order to verify their influence on the fiber-matrix interface properties. </span>
−
−	<span style="text-align: center; font-size: 75%;">The physical process, corona treatment, was applied in the kraft paper with different discharge dosages, while the chemical treatment was performed through the use of several alkali solutions with different concentrations of NaOH. The obtained results from the performed tests shows that the alkali solution treatments improved, up to 57%, the mechanical properties of tensile strength and Young Modulus of the composite material, comparatively with the effect </span><span style="text-align: center; font-size: 75%;">of corona treatment on its surface. These results induce an increase of interface compatibility between the matrix and kraft paper.</span>
