Abstract

Abstract: The use of long natural fibres (LNF) as reinforcement in composite systems for structural applications has been steadily growing in the automotive and construction industries as these materials offer sustainability benefits combined with high specific strength and stiffness. However, the performance of natural fibres has been questioned by a high variability in their mechanical properties and design data for structural reliability analysis of LNF composites are not yet available. Here, we present a statistical study of the elastic modulus, strength and failure strain of a comprehensive set of LNF composite systems. We have found that the variability of LNF laminate properties is similar to that of carbon fibre laminates. We provide recommendations to apply the statistical parameters determined here to the design of natural fibre composite structures. Our findings provide a deeper understanding of LNF composites reliability and are important for the further acceptance of these materials by the industry.
