Mechanical Properties of Rice Husk Fiiled Cashew Nut Shell Liquid Resin Composites

Abstract

The need to have composite materials that are renewable has lead to materials scientists researching on natural fibres. To minimize environmental pollution research into rice husk has been on for a period of time now. In this research cashew nut resin reinforced rice husk composite was fabricated at different particle sizes and different filler loading. The present study reveals that both filler loading and particle size can affect the tensile strength, young modulus, strain at failure, flexural strength, and impact strength. As the % filler content increases all particle sizes (400µm, 600µm and 800µm) shows a quadratic relationship except % elongation at failure which tends to be linear at 400µm. As particle size increases all % filler content shows quadratic relationship which tends to be linear. As particle sizes increases impact strength for 10 and 30% shows a linear equation while 20% shows a quadratic relationship which tends to be linear. In general, RH/CNSR composite could be considered as a potential source of low cost, natural fibre for composites.

Current and future trends in food waste valorization for the production of chemicals, materials and fuels: a global perspective

“…Interrelationships between these variables appeared to be complex, even though the apparent monotonic variation of average particle size with emulsifier concentration makes the emulsifier concentration the most convenient parameter of controlling the particle sizes . In another front, composite materials from cashew nut shell and rice husk have also been prepared . The study aimed for the search of natural fibres in order to minimize environmental pollution.…”

“…The study revealed that both filler loading and particle sizes affected the tensile strength, young modulus; strain at failure, flexural strength, and impact strength of the composite. The study concluded that RH/CNSR composite could be considered as a potential source of low cost, natural fibre for composites . In general, CNSL from the cashew shells has numerous applications in various polymer based industries such as friction linings, clutch disks, paints, varnishes, laminating resins, cashew cements, polyurethane based polymers, surfactants, epoxy resins, and intermediates for the chemical industry …”

“…Examples of natural fibers that have been used to reinforce CNSL-based novalac or resole type resins include oil palm fibers, 105 sisal fibers, 108 kenaf, 109 hemp bast fibers, 109 buriti fibers, 110 jute fibers, 111 and coconut coir fibers. 112 Other renewable fillers include rice husks, 113 coffee husks, 114 and sawdust. 102 Natural fibers reinforcements are frequently pretreated with an alkali solution (i.e.…”

Optimizing the formulation of e-glass fiber and cotton shell particles hybrid composites for their mechanical behavior by mixture design analysis

“…The utilization of these natural fillers has been due to its monetary benefit during processing, high specific strength, comparatively low density and the bio-degradability, thereby reducing the environmental contamination. 5 The idea of adding particles of sub-micro-or nano-scale into polymers is one of the most fascinating subjects in the current decades. 6 One of the methods to augment the mechanical properties of fiber-reinforced polymer (FRP) composites is to progress the properties of the epoxy matrix by integrating second-phase modifiers into the resin.…”
