Polymer composites reinforced with natural fibers have been developed in recent years, showing significant potential for various engineering applications due to their inherent sustainability, low cost, light weight and comparable mechanical strength. Sisal is a natural fiber extracted from leaves of Agave Sisalana plants and substituted for natural glass fiber. Six different combinations of specimens were prepared with sisal, sisal-glass and glass fibers with epoxy as matrix at two different fiber orientation of 0-90° and ±45°. Mechanical characterization such as tensile, flexural and impact testing were done to analyze their mechanical strength. It is found that the hybrid composite sisal-glass-epoxy has better and comparable mechanical properties with conventional glass-epoxy composite and thus provides a viable, sustainable alternate polymer composite.

Average Shear

In this study, the effects of using aligned multi-walled carbon nanotube (MWCNT) nanofoam films as adhesive reinforcements to enhance the shear strength of composite joints are examined. The MWCNT reinforced adhesive nanofoam films are used to bond carbon/epoxy composite adherends. Mechanical characterization of the samples is performed using single lap joint samples to measure average shear strengths experimentally. Shear strength and other multifunctional properties of such nano-adhesives are discussed employing the results obtained in this work.

Use of natural fibres as reinforcement in polymeric composites has been increased during last few decades. They are potential alternatives to synthetic fibres due to their excellent properties like light in weight, biodegradable, abundant, satisfactory strength etc. Various parts of automobiles are being made by natural fibres that improved fuel efficiency and reduced emissions. The present study focuses on developing new polymer composites by reinforcing walnut shell particulate on the basis of different weight fractions. Mechanical characterization was done for the developed composites which include evaluation of tensile strength, impact strength and hardness. Different weight fractions of walnut shell particulate were used including 0%, 10%, 15% and 20%. Maximum tensile strength was achieved in case of 10% walnut shell reinforced composites. Maximum impact strength and hardness were achieved in case of 20% and 15% reinforcement respectively.
