Comparativa de propiedades de tracción, compresión, cortadura en el plano de materiales compuestos con fibras naturales

Developing a sustainable industry based on respectable materials with the environment, through optimal processes with low impact is a fundamental aim, but it remains a considerable challenge to achieve. Despite the large amount of research on composite materials in natural fibers, the limitations in the results have been obtained, being usual to find mechanical results with a wide coefficient of variation and values ​​much lower than expected. The industry of products with bamboo fiber has increased in decorative applications because it is one of the lowest cost raw materials. However, there are limited structural applications, due to the low mechanical properties. A study of the methodology and the extraction area has been carried out in order to maximize the Young's modulus, doubling the value with respect to the E-type and epoxy glass material. Once, continuous networks such as linen, sisal, silk and cotton have been reduced, to develop a unidirectional tape semi-impregnated by a winding process, which allows the fabrication of structures with curvature, with comparable shear values ​​in the plane with the reference material. Finally, in addition to the extensive campaign of mechanical tests, three demonstrators have been manufactured with their respective respect to show the capacity of use and the limitations of the materials. Environmental terms, industrial sectors such as wind or automotive.
