Abstract
There have been numerous endeavors to replace synthetic fibers with natural fibers in fiber reinforced composites, due to increasing environmental alertness and diminution of oil assets. The information that natural fibers are existing inexpensively and in plenty, being biodegradable and low density, have driven many scientists throughout the world to reconnoiter their application potential in several industrial segments. Nevertheless, natural fibers also require some confines such as high moisture absorption and subsequent swelling and degradation, poor chemical and fire resistance, high dispersion of mechanical properties, poor interfacial interactions with polymeric matrices. Consequently, there is an enormous concern to modify the surface of natural fibers through many techniques, in order to overcome their intrinsic downsides and to effectively utilize these materials in different applications. The chemical treatment of fiber is intended at improving the adhesion between the fiber surface and the matrix. Modification in fiber surface results with increase in fiber strength. This study compares the result of different types of surface treatments of natural fibrous materials, chiefly Calotropis procera and Sisal fibers, on the mechanical properties of fiber composites. The application of surface treatments on fibrous materials can improve the compatibility with composite materials.
Highlights
The growing ecological and environmental consciousness has driven efforts for development of new innovative materials for various end-use applications
The proposed new composites provide high flexural strength which clearly shown that this natural fiber can be used instead of other natural fibers which is having low strength
Despite the fact this study produces a new natural fiber into the research but has some limitations, this study considered the weight proportion ratio of fiber upto composite by 60% each, in future this can be extended with various proportions to find the optimum proportion ratio for effective results
Summary
The growing ecological and environmental consciousness has driven efforts for development of new innovative materials for various end-use applications. Environmental and economic alarms are motivating research in the expansion of novel materials for buildings, furniture, packaging and automotive productions. Attractive are the new materials derived from natural renewable resources which prevent further stress on the environment such as that caused by the depletion of already dwindling wood resources from forests. The potential of use of natural fibers, especially as composite reinforcement, depends largely on the increasing of regulation and its commercial characteristics, namely by creating standards for their production and post-treatment. The scientific community has a crucial role in relation to the releasing of accurate and fully characterized studies allowing a robust increase in fundamental knowledge about natural fibers
