“…Pre-treatment methods like treating with standard chemicals and heat treatment are done to improve the suitability of a natural fibre in a composite and also to improve its strengths. 8 -10 On the other hand, minerals taken from the earth are also used by many researchers as reinforcements in composites and other materials.…”

The present research has been made to investigate the characteristics of a new composite material made up of limestone as particle reinforcement. New composites are made by taking limestone particles in five different sizes and jute as woven reinforcement in polypropylene matrix. Mechanical characteristics of the composites that include strengths against tension, compression, flexural, impact and hardness are evaluated and a comparative investigation is made among the composites. The effect of particle size on the properties is analysed and found that the composite with medium particle size bears the highest strength in all aspects. In addition, microscopic image analysis is carried out to investigate the distribution of particles, bonding capacity and other morphologies. The results showed that limestone will be apt particle reinforcement and its presence enhances all the characteristics of the composite.

“…In another study, 10% peroxide, 10% benzoyl chloride and 5% alkali were used to treat Vetiveria zizanioides. It was seen from the results that benzoyl chloride treatment increased the mechanical properties by removing the unwanted constituents to enhance surface roughness of the fibers leading to better interfacial fiber and matrix bonding [8]. The benzoyl chloride treated and untreated Impomea pes-caprae fibers were characterized for chemical analysis, thermal stability, crystallinity index and the so developed composites were analyzed for mechanical properties namely tensile, flexural and impact as per ASTM.…”

Natural fibers are widely used in the various lightweight and medium load applications due to their vital advantages. Cyperus pangorei is abundantly found on the river banks. The current study deals with the usage of Cyperus pangorei fibers that were retted using a manual retting process in the brake pad formulation. The fibers retted were treated with benzoyl chloride to enhance adhesion characteristics. The benzoyl chloride treated and untreated Cyperus pangorei fibers were used in the development of brake pads with other ingredients constant as per industrial practice. The developed brake pads were analyzed for its physical, chemical, thermal and mechanical properties as per industrial standards. The tribological performance of the brake pads was analyzed using a pin-on-disc tribometer as per ASTM G-99-05. It was proved that benzoyl chloride treated Cyperus pangorei fibers based brake pads showed excellent performance characteristics compared to untreated one due to better bonding with matrix causing good contact plateaus formations as confirmed from Scanning Electron Microscopy.

“…[1][2][3][4] Before using a natural fibre, it must be properly synthesized to improve its characteristics. [5][6][7] Experimentations have showed that the green fibres are sometimes on par with the man-made fibres and some are better than that of the man-made fibers. [8][9][10] A clear understanding has been given in all these researches that even though natural reinforcements are used in polymeric composites, the nature of degradability of composites could be achieved only to certain extent.…”

The research on polymeric composites is always in the stage of enhancing the properties. Several researches have been explored in recent decades to investigate the behaviour of both man-made fibre and bio-fibre-reinforced composites. In all these works, an artificial polymeric resin has been utilized as the matrix and it has been revealed that though they provide competent properties, the composites are partially degradable. To enhance the degradability to the fullest extent, both the reinforcements and the matrix must be biodegradable and this could be achieved only if both are derived from natural sources. During the synthesis of a bio-resin, a series of treatments must be followed to make it in to a usable form. The present work addresses a comprehensive survey about various bio-resins, their applications, various synthesis methods followed and the challenges faced during incorporation of reinforcement during composite formulation. The work also gives a clear picture on the challenges faced during characterization of green resin-based composites.
