TL;DR: In this article, the optimum mixing of fiber and resin is achieved by using Taguchi method, flexural rigidity and hardness of Sisal and banana (hybrid), Roselle and banana(hybrid) composite at dry and wet conditions were studied.
Abstract: In this research, natural fibers like Sisal (Agave sisalana), Banana (Musa sepientum) & Roselle (Hibiscus sabdariffa) , Sisal and banana (hybrid) , Roselle and banana (hybrid) and Roselle and sisal (hybrid) are fabricated with bio epoxy resin using molding method. In this paper the optimum mixing of fiber and resin is achieved by using Taguchi method. In this work, flexural rigidity and hardness of Sisal and banana (hybrid), Roselle and banana (hybridand Roselle and sisal (hybrid) composite at dry and wet conditions were studied. Hardness test were conducted using Brinell hardness testing machine. In this work micro structure of the specimens are scanned by the Scanning Electron Microscope.

TL;DR: In this article, a research project has been carried out at the National Technical University of Athens, Greece, to develop composite panels reinforced with cotton fibers, with special attention given to the effect of the fiber type on the structural properties of the plates.
Abstract: A research project has been carried out at the National Technical University of Athens, Greece, to develop composite panels reinforced with cotton fibers. The primary aim of the project is to examine the mechanical properties of such panels for use in secondary structural members such as wall or door systems. The use of natural fibers such as cotton, flax or sisal fibers has the primary advantage of being eco-friendly, low cost and low weight compared to glass fibers on the expense of lower structural properties. This paper presents results from experimental work on composite plates made from polyester resin reinforced with cotton fibers, with special attention given to the effect of the fiber type on the structural properties of the plates. The results from this study showed that the structural performance of cotton fiber composites is satisfactory for structural parts with low requirements, such as wall panels or doors. The present results for cotton fiber composites are also compared to testing results from previous studies on composites with flax/sisal fibers.

TL;DR: In this article, the impact performance of sisal fiber reinforced epoxy composites was analyzed by using a surface tensiometer and dynamic mechanical analyzer, and the results indicated that the chemical treatments brought about strong bonding between sisal bundles and the epoxy matrix.
Abstract: To obtain comprehensive knowledge of the interfacial effect on the impact performance of sisal fiber reinforced epoxy composites, the fiber surface was modified in different ways prior to compounding. By using a surface tensiometer and dynamic mechanical analyzer, interfacial interactions in the composites were characterized. The results indicated that the chemical treatments brought about strong bonding between sisal bundles and the epoxy matrix. The subsequent impact tests revealed that the microfailure mechanism involved is a function of interfacial adhesion and fiber length continuity (i.e., continuous or discontinuous fiber). In the case of unidirectional laminates, an optimum fiber treatment should be able to result in an increased affinity between fiber bundles and matrix and a decreased intercellular adhesion. In this way, extension and uncoiling of the spirally arranged microfibrils, a main energy consumption process of plant fibers, can impart significant toughness to the composites. For short fiber composites, the interfacial strength should be properly tailored so as to increase energy dissipation through debonding and pull-out of fiber bundles.
