Influence of the anisotropy of sisal fibers on the mechanical properties of high performance unidirectional biocomposite lamina and micromechanical models

Risultato della ricerca: Articlepeer review


High performance biocomposites reinforced by sisal fibers, are between the most promising materials that couldbe used in various fields, from automotive to civil constructions, thanks to their good mechanical performance, aswell as to the low cost and the great availability of the fiber. Nevertheless, at present their practical use isprevented by the limited knowledge of their mechanical performance. The results of the present study haveshown that the intimate fibrillar structure of the sisal fiber is associated with a high anisotropy involving not onlythe elastic parameters, but also the damage processes with typical fiber splitting phenomena, that influencenoticeably the biocomposite strength under transversal tensile/compressive, longitudinal compressive and shearloading. Also, they have permitted to implement new micromechanical models that can be used at the designstage, in all practical structural applications where low cost green biocomposites reinforced by sisal long fibercould be advantageously used.
