AbstractThe role of nanoclays on the performance improvement of structural composites made from flax fibers was investigated. The nanoclays were at first dispersed in the polymer matrix before the impregnation the flax fibers. The results obtained for the epoxy based composites demonstrate that specific treatment of the fiber surface can bring up the performance of composites such as the tensile strength, tensile modulus and the interfacial strength of the composites. However, the level of improvement on the properties of the composites is much better in the presence of dispersed nanoclays. In principle, the composite strength and modulus are mainly controlled by the fibers if the fiber-matrix interface is optimized. Thus the observed improvements in composite strength and modulus can be interpreted by the nanoclays role in the improvement of the load transfer from the matrix to the fiber and hence enhancement of the interfacial properties. This study confirmed that nanoclays can be used to upgrade the mechanical performance of natural fiber composite and also can reduce the gas diffusion through the material resulting in the enhancement of the fire resistance.
