Fine powder produced from coconut shells (CSP) has been found to be excellent functional filler in polypropylene, significantly increasing flexural and tensile moduli, slightly increasing tensile strength, and good retention of Izod impact strength at weight percentages less than 20 %. The research presented in this paper explores the temperature processing window for coconut shell powder filled polypropylene and the change in the rheological behavior of the polypropylene due to the addition of CSP as functional filler in this processing temperature window. The reason for the simultaneous increase in flexural modulus, tensile strength, and good retention of Izod impact behavior is also investigated

The use of natural fibers in polymer matrix composites are increases because of their advantages like good stiffness, strength, environmental friendly, low cost and biodegradable. In the present investigation, hybrid fiber reinforced composites are fabricated using areca fiber and coconut shell powder (CSP) as reinforcement in epoxy resin. Unidirectional areca fiber and CSP reinforced epoxy composites were fabricated by varying the overall fiber loading (10, 20, 30, and 40 wt.%) and different weight ratios of areca fiber and CSP (1:1, 1:3, and 3:1). Effect of fiber loading and weight ratio on mechanical properties like tensile strength, tensile modulus, flexural strength, flexural modulus, interlaminar shear strength (ILSS), impact energy and surface hardness of hybrid composites were evaluate experimentally. All the hybrid composite samples fabrication and mechanical testing was done as per ASTM standards. The experimental investigation reveals that the tensile, flexural and ILSS properties show their maximum values at 30 wt.% of fiber loading with areca fiber and CSP weight ratio as 1:1. From the impact and hardness results it has been found that composites with areca fiber and CSP weight ratio as 3:1 and 1:1 respectively shows their maximum values at 40 wt.% of fiber loading. Interfacial analysis of the hybrid composites were also observed by using scanning electron microscope (SEM).

The objective of this investigation is to fabricate a natural material based composite and study its tensile strength. The water hyacinth is a plant which is considered as an unwanted wild growth which is detrimental to the water bodies. It affects the oxygen and nutrients content of the fresh and sewage water and also hampers the flow of the water, thus leading to stagnation and flooding. In this method the water hyacinth was harvested and used as a reinforcing fibre in its untreated condition [1]. Our nation having a long sea shore is blessed with coconut trees. All the parts of the coconut tree are being used for various purposes [2-4]. Based on literature 15% by weight of powdered coconut shell was used as particulate reinforcement in this study [5, 6]. Hence this experimental work is an effort to fabricate a composite using the waste water hyacinth fibres and the coconut shell powder using an epoxy resin matrix through hand layup technique and subjected to tensile loading. This test results show good ultimate tensile strength.

Coconut Shell Powder (CSP) was derived from industrial Making Anti-Mosquito can potentially be used as filler in materials composite. The investigation on the utilization of CSP as filler in a polyester matrix has been done with the purpose to obtain the best CSP fillers size in Unsaturated Polyester (UPR) composites in producing the best mechanical properties such as tensile strength, impact strength  and water absorption. In this study, UPR was mixed with CSP at the sizes 50 mesh, 70 mesh and 100 mesh with comparison of CSP: Unsaturated Polyester 20:80 (w/w) by using hand lay-up method. The result of mechanical properties showed that, at a ratio of CSP: PE (20:80), the maximum tensile strength obtained is 42.558 MPa with the size of CSP 70 mesh. The test on impact strength was found that the increasing only occured with the size of CSP 100 mesh at 6083.47 J/m2. For absorption test, the highest water absorption occured at the first day,  water absorption increased with increasing the amount of filler and the most CSP  absorbed  water at 70 mesh.

Coconut shell is one of agricultural wastes that having low commercial value. This research is objected to use coconut shell as the base material of producing surfactant. The use of coconut shell is basically due to its content of lignin, about 29,4%. The objective of this research is to obtain isolate lignin with increasing chatalis NaOH and H2SO4 with lignin identification, the effect of temperature and agitation rate of producing surfactant. The research was done in a reactor with temperature of 100 0C, 110 0C, 120 0C, 3 hours reaction time, pH 6, 80 rpm, 90 rpm, 100 rpm agitation rate, and coconut shell as the base material. Dry coconut shell is grinded and the powder is collected to be reacted. The coconut shell powder is reacted with sodium bisulfite solution with variation in ratio of 1:0,5.  The product is filtered to get filtrate and residue. The filtrate is further analyzed by using the FT-IR spectrophotometry method. From the research we get maximum purity of surfactant at sodium bisulfite with reactant ratio of 1:0,5;  Speed 100 rpm and temperature 120 0C.
