In this study, physical, mechanical, and flammability properties of coconut fiber reinforced polypropylene (PP) composite panels were evaluated. Four levels of the coir fiber content (40, 50, 60, and 70 % based on the composition by weight) were mixed with the PP powder and a coupling agent, 3 wt % maleic anhydride grafted PP (MAPP) powder. The water resistance and the internal bond strength of...

In the context of sustainable development which is a balancing act between the fulfilment of human needs and the protection of the natural environment, the use of natural fibers such as coir in geotechnical applications is desirable. Reinforcing the soil with coir fibers/coir geotextiles is a cost effective solution to the ground/soil improvement problems. The effects of fiber parameters on the...

Abstract In this research, the hybrid natural fiber composite specimens were fabricated with a 64 wt% epoxy resin matrix, 20 coir fiber, and 16 of various fibers by hand-layup method. The influences (Coir, Jute, Flax, Cotton, Human Hair, Sisal, Kenaf, Calotropis) on mechanical characteristics (tensile, flexural, impact strengths) drilling properties (delamination factor ovality) Coir-fiber base...

Abstract-Since highways are widely used modes, it is necessary that it should be maintained properly. Subgrade being the support for the whole pavement, it needs the utmost care in its construction. Many suggestions have been put forward by various scientists to improve the subgrade. The usually adopted methods are stabilization methods. This paper deals with the improvement of properties of ka...

In present investigation the wear behavior of treated and untreated coir dust filled epoxy resin matrix composites were studied. The effect of treated and un treated coir dust concentration (10%, 20% and 30%), varying loads (10, 20 and 30N) and varying velocities (300, 400 and 500) on the abrasive wear rate of composite has been analyzed. The abrasive wear property of the composite is examined ...

BACKGROUND Coir is a commercially important natural fiber obtained from the coconut husk. Coir can be woven into strong twine or rope, and is used for padding mattresses, upholstery, etc. Coir industry provides a major share of occupation to the natives of Alappuzha district of Kerala State. It has been noticed earlier that there is increased incidence of nasobronchial allergy among the populat...

Reinforced polymer composites have played an ascendant role in a variety of applications for their high meticulous strength and modulus the fiber may be synthetic or natural used to serves as reinforcement in reinforced composites. Glass and other synthetic fiber reinforced composites consists high meticulous strength but their fields of applications are restrained because of their high cost of...

Coir fibers received three treatments, namely washing with water, alkali treatment (mercerization) and bleaching. Treated fibers were incorporated in starch/ethylene vinyl alcohol copolymers (EVOH) blends. Mechanical and thermal properties of starch/EVOH/coir biocomposites were evaluated. Fiber morphology and the fiber/matrix interface were further characterized by scanning electron microscopy ...

Mechanical properties of the fibers extracted from the areca are determined and compared with the other known natural fiber coir. Further these Areca fibers were chemically treated and the effect of this treatment on fiber strength is studied. Areca fiber composite laminates were prepared with randomly distributed fibers in Maize stalk fine fiber and Phenol Formaldehyde. Composite laminates wer...

Coir pith, a by-product of industry, renewable sourceis dark brown in color, fibrous in condition. The physical properties and anatomical studies of various ages of coir pith were done to determine the efficiency of formation of primary and secondary cell wall in fresh and old coir pith.The cell wall structure, lignin composition and the anatomical view in the collected coir pith were examined ...
