Abstract

Little attention has been paid to joining unidirectionally reinforced high strength natural fibre composites. Therefore the main objective of the paper is to investigate the influence of joint geometry on the strength of joints. Epoxy bonded single lap shear joints (SLJs) between henequen and sisal fibre composite elements have been manufactured and tested to assess the strength of the structural bonds. The joints have been successfully modelled using finite element analysis and experimental measurements have been verified theoretically. A second phase of the research concerned the performance of integrated joints, termed "intermingled fibre joints" (IFJs) and "laminated fibre joints" (LFJs). These joints are manufactured by intimately combining fibre bundles (IFJs) or laminating layers of fibre bundles (LFJs). These joint configurations possess much higher lap shear strengths than the single lap shear joints and the failure modes of the three joint configurations are compared.
