​Coconut Shell Powder Reinforced Epoxy Composites: A Review

Abstract

Fibers are of two type’s natural fiber and synthetic fiber. Natural fibers include those made from plant and animal sources. The natural fiber composites can be very cost effective material and have turned out to be an alternative solution to the ever depleting petroleum sources and have reduced the nuisance of pollution. The production of complete natural fiber based materials as a substitute for petroleum-based products would not be an economical solution. A more viable solution would be to combine petroleum and bio-based resources to develop a cost-effective product with diverse applications. The application of natural fiber-reinforced composites has been extended to almost all fields such as building and construction industry, storage devices (post-boxes, grain storage silos, bio-gas containers etc.), furniture and electrical devices. Coconut shell is a lignocellulosic agro waste which is burnt or left to decay in environment. These can be a very interesting material as filler in biodegradable polymer composites, due to its good thermal stability compared to other agricultural waste. In context to this, review was carried out to assess the coconut shell powder reinforced epoxy composites and their mechanical, structural and thermal properties.

Mechanical and Wear Properties of Developed Cellulosic Fiber-Particles Hybrid Reinforced Epoxy- Based Composites for Automotive Application

“…This result is actually in correlation with Figure 7 because according to Oladele et al [30] high density enhances high material hardness. Asokan et al [48] reported a variation in natural fibre density of 1.2 -1.6 g/cm 3 . From the results presented in Figure 9, it can be observed that the reinforced composite fell below this range, except for the composite reinforced with 9wt% sisal fiberpaper particles, which was in close proximity.…”

“…The versatility of these materials is notable because they can be fashioned into an array of shapes and sizes [2]. Furthermore, they offer exceptional strength and stiffness, coupled with resistance against the corrosive effects of the environment [3]. Among the various categories of polymeric composites, one notable type is epoxy.…”

“…The sisal fiber was extracted employing soil retting method, subjected to surface treatment, and combined with paper particles. Following preparation of the reinforcements, predetermined compositions (3,6,9,12 and 15 wt %) were mixed with epoxy resin before being poured into the moulds using hand layup process and were allow to cure. The study focused on the mechanical, wear, and water absorption properties, as well as the surface morphologies of the developed composites.…”

Experimental and simulation study on active vibration control of rotating machines using coconut-husk fiber composite

“…The effect of Coconut shell powder on the mechanical properties of coconut fiber reinforced epoxy composites has been extensively studied [8][9][10]. Coconut shell powder (filler) at different contents and various proportions of coconut fiber (reinforcement) had been used to prepare the epoxy composites.…”
